Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 1st of May 2025 After the previous week's geomagnetic disturbances, as described in last week's GB2RS, the last seven days have been relatively quiet. The Kp index has mostly been in the ones and twos, however the rise to a Kp value of four on Thursday the 1st of May could herald a return to unsettled conditions. The solar flux index peaked at 170 on the 24th of April, before declining to 148 at the end of the month. HF conditions have been acceptable rather than outstanding and many stations struggled to work DX at times during International Marconi Day on the 26th of April. Nevertheless, there is DX about including ZS8W Marion Island, TX9A Austral Islands and HD8G Galapagos Islands. A look at the Proppy propagation prediction tool will help you work out the best times for making a contact with each station and on each band. You can find it by going to rsgb.org/propagation-tools Looking ahead, a large sunspot has rotated into view. Now designated 4079, this region has returned and was previously sunspot region 4055. It has already emitted an M-class solar flare, and we may expect greater activity as it becomes more Earth-centric over the next week. NOAA predicts that the solar flux index will climb again in the coming week, perhaps rising to between 160 and 165. Geomagnetic disturbances are also due to rise, with the Kp index forecast to reach five on the 5th and 6th of May. If this becomes a reality, expect lowered MUFs and poorer HF paths, especially over the poles as the Kp index rises. And finally, this week traditionally marks the start of the Sporadic-E season so keep an eye on 10m and 12m for short- and medium-range openings to Europe. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of high-pressure Tropo weather weakened a little as last week ended and we'll see the return of unsettled conditions with showery rain, perhaps even the odd thunderstorm. This is unlikely to lead to a total removal of high pressure and Tropo will still be worth looking for, especially over the western side of the UK. Some models place a new high just west of Britain during the coming week. This means that the rain prospects are not great, although probably just enough for a hint of rain scatter in any isolated heavier showers. The HF bands sounded a bit ‘watery' at times last week, which is a classic sign of potential aurora to explore on the higher bands. Look out for aurora in the coming week if the Kp index climbs above five. Meteor scatter is worth thinking about and, after last week's Lyrids, we now have the Eta Aquariids shower peaking in the early hours of the 6th of May. Remember that Sporadic-E ionisation is largely composed of long-lived meteor ions, so be on watch for Es openings. From now onwards through to mid-September, Sporadic-E will dominate the lower VHF bands, so check the clusters for signs of activity. Remember that Es starts on 10m and moves HF as an opening develops, even reaching 2m in the peak summer. Unlike Tropo, Es events are often fleeting, so the best you can do is monitor conditions as the Es intensifies and be ready when it reaches the band you want. Don't forget to check the daily Es blogs on www.propquest.co.uk which discuss the potential links between location of jet streams and Es formation. EME path losses are increasing, but apogee is still a week away. Moon declination passed maximum last Thursday so Moon windows are shortening along with reducing peak elevation. 144MHz sky noise is low all week. And that's all from the propagation team this week.
SpaceTime with Stuart Gary | Astronomy, Space & Science News
In this episode of SpaceTime, we unveil groundbreaking evidence that challenges previously held theories about the origins of Earth's water. Recent findings published in the journal Icarus indicate that rather than being delivered by asteroids and comets, Earth's water may have formed alongside the planet itself. The study utilizes a unique meteorite known as the enstatite chondrite to reveal a rich source of hydrogen essential for water formation, reshaping our understanding of how life-sustaining conditions developed on Earth.The Enigmatic Magnetic Field of MarsNext, we delve into the curious case of Mars's magnetic field, which has puzzled scientists for decades. A new study suggests that the strange magnetic signatures observed on the Red Planet could be attributed to a partially molten core predominantly covering the southern hemisphere. This research provides fresh insights into Mars's geological history and the implications for its atmospheric evolution, as the planet transitioned from a warm, wet environment to the arid desert we see today.The Lyrids Meteor ShowerAdditionally, we celebrate one of humanity's oldest known meteor showers, the Lyrids, which are currently dazzling skywatchers. First recorded over 2,700 years ago, these meteors originate from comet Thatcher and promise a beautiful celestial display. Although not as prolific as other meteor showers, the Lyrids offer a captivating spectacle for stargazers, with expectations of 10 to 15 meteors per hour during peak viewing times.00:00 Space Time Series 28 Episode 50 for broadcast on 25 April 202500:49 New evidence on the origins of Earth's water06:30 Analysis of the enstatite chondrite meteorite12:15 The mystery of Mars's magnetic field18:00 Implications of a partially molten Martian core22:45 Overview of the Lyrids meteor shower27:00 Summary of recent astronomical findings30:15 Science report: Health risks linked to food additiveswww.spacetimewithstuartgary.comwww.bitesz.com
The mild nights of spring are good times for skywatching. Only one thing is missing: a great meteor shower. The best showers are clustered in fall and winter, with the Perseids of August sometimes joining the list. Although the season doesn’t offer a great shower, a pretty good one should reach its peak tomorrow night: the Lyrids. Under a dark sky, you might see up to a couple of dozen meteors per hour between midnight and dawn. The number of meteors increases closer to dawn, as your part of Earth turns more directly into the meteor stream. Unfortunately, by then the waning Moon will be in the sky, so its light will compete with the fainter meteors. One good thing about meteors, though, is that you don’t have to wait for a shower to see them. A shower occurs when Earth passes through a stream of small bits of dust and rock shed by a comet or asteroid. There are many showers through the year, but only a few are noticeable. But bits of rocky debris are scattered throughout the solar system. So on any dark night, you can see several meteors zipping across the sky. And these “random” meteors can come from any direction and blaze across any part of the sky. So if you have a chance, look for the Lyrid meteor shower in the wee hours of Tuesday morning. If not, then take advantage of just about any clear, dark night to look for meteors flashing across the heavens. Tomorrow: a steady light far across the galaxy. Script by Damond Benningfield

Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 24th of April, the 80m Club Championship runs from 1900 to 2030UTC. Using PSK63 and RTTY, the exchange is signal report and serial number. The UK and Ireland DX CW Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. UK and Ireland stations also send their district code. The SP DX RTTY Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. SP stations also send their province code. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 17th of April 2025 Last week was characterised by increased Kp index numbers and severe geomagnetic storms, peaking at G4. These drove down maximum usable frequencies and disrupted DX contacts, especially on the higher HF bands. The solar wind speed increased from 380 kilometres per second to around 500 kilometres per second on the 15th and an increase in plasma density was noted as well. Subsequently, the Kp index peaked at 7.67 on Wednesday the 16th, causing visible aurora alerts in the UK. This was caused by a pair of CMEs that left the Sun on Sunday the 13th of April. We had a total of 22 M-class solar flares over four days, so a CME event was inevitable. Unsettled geomagnetic conditions are a feature on the declining side of a solar cycle, so we could unfortunately be in for many more. According to Propquest, MUFs over a 3,000km path fell to below 18MHz for long periods on Wednesday the 16th, before climbing to around 21MHz at the end of the day. Meanwhile, the solar flux index fell from a high of 170 on Friday the 11th of April to a low of 148 on Wednesday the 16th of April. Next week, NOAA predicts that the SFI will start the week around 145 but could increase to 165 as the week progresses. Unsettled geomagnetic conditions are forecast for the 22nd to the 24th of April, with a predicted maximum Kp index of four. As always, keep an eye on solarham.com for daily updates, but more importantly, get on the bands, which are a much more effective guide to HF propagation! And now the VHF and up propagation news from G3YLA and G4BAO The current period of unsettled weather looks likely to continue into the coming week. This does not mean rain every day, but periods of rain or showers with some intervening drier spells. These drier interludes are not really dominated by high pressure, just gaps between the wetter periods, so it's unlikely to produce much significant Tropo. In terms of propagation, there may be some rain scatter, although it won't be very reliable. However, the prospects for meteor scatter are more promising with the peak of the Lyrids due on Tuesday the 22nd of April. It is worth checking up on procedures for meteor scatter working if you've not done it before and you may find a new part of the hobby to add to your operating schedule. The prospects for aurora continue to be raised by what seems like an almost daily supply of aurora alerts. Continue to monitor the Kp index for signs of elevated values, where Kp is above five, for radio activity. Early signs such as fluttery signals on the LF and HF bands may suggest it's worth looking on the VHF bands for auroral activity. As we move towards the new season it is good to get into the habit of looking for Sporadic-E. The Propquest website www.propquest.co.uk shows several useful components for analysing the Es prospects. If you look at the position of the jet streams shown on the Es blog tab, these can produce favourable conditions geographically to give a hint of the right direction in which to listen. The opening season typically favours 10m or 6m. EME path losses are now decreasing towards perigee on Sunday the 27th of April. Last Friday, the 18th of April, saw minimum Moon declination, so Moon windows will lengthen along with peak elevation. 144MHz sky noise starts this week very high but decreases to low as the week progresses. And that's all from the propagation team this week.

The 365 Days of Astronomy, the daily podcast of the International Year of Astronomy 2009
I'm Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. April of 2025 brings us the annual Lyrid meteor shower, all the naked-eye planets, and plenty of lunar close encounters. We'll start by talking about this month's big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me. April 22nd – LYRID METEOR SHOWER – Around 10-20 meteors per hour, the Lyrids are a minor shower, but a meteor shower indeed. And this year, the Moon will rise very early in the morning, meaning we have clear skies until that point, and even then, it's not so bright. The shower is greatest on the 22nd, but you might see some on the 21st and 23rd as well. Just remember each meteor is a piece of debris left over from a comet, and we're crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. There is no real best time to see these this year, but the later, the better. You never know when you'll see something awesome. Some advice for watching: - Find a dark location and lie down in a reclining chair or something that insulates you from the ground. - Check the weather to see if the skies will be clear. - Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.

GB2RS News Sunday, the 6th of April 2025 The news headlines: Last chance to submit your question ahead of Saturday's RSGB AGM Tom Wardill, 2E0JJI has been appointed as RSGB Maker Champion Reduced exam slots over Easter weekend The RSGB 2025 AGM is taking place at 10 am next Saturday, the 12th of April. The Society is encouraging RSGB members to take the time to vote for the two resolutions that need your approval. During the AGM, Board members will be answering your questions. Whether your question is about the RSGB, the Board, any of the RSGB services or even the future of amateur radio, your contribution to the discussion is important. Priority is given to questions submitted live by Zoom or by the Society's web form, so get in touch now rather than waiting for the live chat option on the day. The Zoom question deadline is 9 am on Monday, the 7th of April, and the deadline for submitting a written question is when voting ends at 0900 on Thursday, the 10th of April. Following the formal business of the AGM, the RSGB is delighted that RSGB President John McCullagh, GI4BWM will be sharing his review of 2024. There will also be announcements of trophies and awards, the construction competition results, as well as a presentation about the Society's strategy, which will be led by Board Director Mark Jones, G0MGX. There will be contributions from Board Director Ben Lloyd, GW4BML; Spectrum Forum Chair Murray Niman, G6JYB; and Bob Beebe, GU4YOX who at that point will be the new RSGB President. Make sure you don't miss out by putting the date in your diary now. Go to rsgb.org/agm to find further information. The RSGB is pleased to announce that Tom Wardill, 2E0JJI has been appointed as the RSGB Maker Champion. In his role, Tom will assist the RSGB to take amateur radio to new audiences in the hackspace and makerspace communities. Tom will also investigate opportunities to encourage crossover in both directions, offering new areas of experimentation to more traditional license holders. If you have any ideas you'd like to discuss with Tom or would like to congratulate him on his appointment, please email him via maker.champion@rsgb.org.uk A reminder that the RSGB remote invigilation team will be taking a break over the Easter weekend. You will be able to book to take an exam on Friday, the 18th and Saturday, the 19th of April; however, no exam slots will be available on Sunday, the 20th or Monda,y the 21st of April. Exam bookings will resume as normal after that. The next webinar in the RSGB's Tonight@8 series will be live tomorrow, Monday the 7th of April. Nick Wood, M0NTV will show you how to use a regular glue stick housing in a rather novel way to form the basis of a variable tuning inductor in a homemade 40m receiver. Nick has a lifelong fascination with radio and electronics, and an insatiable curiosity to discover how things work. His passion is for designing and building his own radio equipment, particularly SSB transceivers, and he has just completed his sixth. Visit rsgb.org/webinars to find out more. Join the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of April 2025 We had a week of mixed solar conditions, but it ended with an SFI of 182 and a Kp of 3.67 on Thursday, the 3rd of April. The geomagnetic field declined to quieter levels following a prolonged period of active, Kp4 conditions earlier on Wednesday due to solar wind enhancements. This impacted propagation, with the critical frequency struggling to get much above 7 MHz on Wednesday. Compare this with the following day, when the critical frequency hit 10.4MHz by 0830 UTC. Nevertheless, there was DX to be worked on Wednesday with FT8 allowing signals from Australia, Japan, Indonesia, China, and Surinam to get into the UK on 21MHz. The solar proton flux was also high on Tuesday, the 1st of April, affecting signals passing through the polar regions, but this had declined by Thursday and was heading back to normal levels. This was due to a large CME observed off the east limb of the Sun on Frida,y the 28th of March. If it had been Earth-directed, we may have seen a massive aurora. Next week, NOAA predicts that the solar flux index will stay in the 175-185 region. A Kp of six was forecast for yesterday, Saturday the 5th of April, followed by a further period of unsettled geomagnetic conditions due to an enhanced solar wind. If this is the case, we may not get more settled conditions until the 14th to the 16th of April. Nevertheless, this remains a good time for North-South HF paths, such as the UK to South Africa, and UK to South America. And now the VHF and up propagation news from G3YLA and G4BAO The old forecasting maxim that the ‘longer a high lasts, the longer it will last' is built upon the presence of blocked upper air weather patterns. When the jet stream gets so distorted into a high-amplitude north/south wave, its lateral movement, from west to east, becomes very slow. On the upper air charts, this takes the shape of the Greek letter omega, and this is the current set-up. It means that the weather associated with it also lasts a long time. In this case, it's the high pressure and its spell of fine weather that is likely to last for the whole of the coming week. The position of the high will change, though, starting over the North Sea and ending over the UK and the nearby Atlantic. This means that Tropo will be the mode of choice for the coming period, which includes the 70cm UK Activity Contest on Tuesday and the 6m UK Activity Contest on Thursday. Rain scatter is unlikely during this extended period of dry weather. The meteor scatter options are still mainly driven by random meteors for the coming period into next week, but the next important shower, the Lyrids, peaks on the 22nd of April. The auroral alerts continue to come through, raising interest. As usual, the clue will be fluttery-sounding signals on the bands, particularly noticeable on CW, but they can also be pronounced on speech transmissions. Monitor the Kp index for values above Kp5. There have been a few trans-equatorial openings to Southern Africa on 50MHz digital modes for the fortunate few who live in the extreme south and southwest of the UK, but it did extend up to Cambridgeshire and Suffolk briefly on some days last week. The long drought of Sporadic-E will soon be over, but we're still in the realms of very isolated events for 10m and 6m, which will be short-lasting. The jet stream, which can be a good clue as to potential locations, suggests looking to Scandinavia, the Baltic and northern Europe. EME path losses are falling again, but Moon declination has been at its highest this weekend, so we have long Moon windows. 144MHz sky noise is low throughout the coming week. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 6th of March 2025 We started last week with geomagnetic disturbances that saw the Kp index rise to a maximum of 5.67 on the 28th of February and then hover around the 4.5 mark for the next couple of days. As predicted, the rest of the week went quite well, with the Kp index in the range of one to four. The solar flux index fell from a maximum of 210 on the 23rd of February to a low of 140 on the 2nd of March. It then climbed back to 160 on the 4th. Over the past week, we have had no X-class and only one M-class solar flare which was on the 5th. As we head into next week, it looks like all the sunspots in the Sun's northern hemisphere have now departed. Nevertheless, the southern hemisphere is still supplying lots of spots so don't panic just yet! HF conditions have been quite good. VK6IF and VK6IA in Western Australia were booming in on 28MHz USB on the morning of Thursday the 6th, as was VK9CU on the Cocos-Keeling Islands. Nigel, VP8TXF and Ian, VP8CIW have been operating from the Falkland Islands ahead of this weekend's Commonwealth Contest and have been worked from the UK on 20m-10m. They are there until the 10th, so get in quick. Other DX to be worked this week includes VU4AX Andaman Islands, 6Y7EI Jamaica, PJ7AA Sint Maarten Island, 4S7KKG Sri Lanka, TY5C Benin, 6W7/ON4AVT Warang Senegal, RI1ANE Antarctica and H44MS Solomon Islands. Next week, NOAA predicts that the solar flux index will start off around 150 and may then climb to 185 by the 16th. A large coronal hole became Earth-facing on the 6th, which may result in unsettled geomagnetic conditions this weekend, the 8th and the 9th. It looks like we can expect unsettled geomagnetic conditions around the 10th to the 16th, with a maximum predicted Kp index of five. And now the VHF and up propagation news from G3YLA and G4BAO The weather divides into two segments; the first, from the middle of last week through to the middle of next week, is rather changeable with low pressure nearby bringing rain or showers and potential for rain scatter on the GHz bands. Eventually, the unsettled weather ends with a cold northerly on Tuesday the 11th and this leads to a new high building from Wednesday into the weekend of the 15th and 16th March. This is good news for Tropo and could possibly be of benefit to those in the UK 70cm Activity Contest on Tuesday the 11th in the western UK, but more generally for the FT8 70cm Activity Contest on Wednesday and the 50MHz UK Activity Contest on Thursday evening. We are still between major meteor showers and therefore must rely upon random activity for now. The next shower of note is the Lyrids on the 21st and the 22nd of April, so we have a while to go yet. The solar activity has continued to produce a regular supply of auroral alerts and fluttery signals on the LF bands, but with a lot of clouds in northwestern areas and southern parts just marginally out of reach for any naked-eye auroras. A few digital camera pictures did surface on the web. Keep an eye open just in case though. Remember Kp equalling five or greater is where we need to be. Lastly, the Sporadic-E prospects are still relatively low with only the odd minor blip up to around a Sporadic-E critical frequency of 5 to 7MHz, often around the middle of the day. This contrasts with the morning and evening windows in the main season. It is enough to promote interest in the 10 or 6m bands, but almost certainly a fleeting moment. EME path losses rise all this coming week and moon declination falls with associated shortening Moon windows and reducing peak Moon elevation. The best results will therefore be early in the week. 144MHz sky noise is moderate this weekend, falling to low in the week commencing the 10th. And that's all from the propagation team this week.
Episode 208 In this episode of the Observers Notebook podcast, host Tim Robertson talks to the Meteor Section Coordinator, Bob Lunsford about the upcoming Lyrids and eta Aquariids meteor showers peaking the evening of April 17-26, 2025 and April 20-May 21 2025.

GB2RS News Sunday the 16th of February 2025 The news headlines: The RSGB has announced its Scout, Cadet and Girlguiding Youth Champion Listen out for stations operating for World Thinking Day on the Air New resources and ideas have been added to the RSGB British Science Week web pages The RSGB is delighted to announce that Samuel McCutchion, M7UEL will be the RSGB's Scout, Cadet and Girlguiding Youth Champion. Sam brings a wealth of hands-on experience to the role having been part of the Scouts from a young age in Beavers and then working his way up to Network. He then progressed to become an Assistant Section Leader. This knowledge will help the RSGB Youth Team to engage and offer amateur radio support to not only the Scouts but also the Cadets and Girlguiding. If you'd like to congratulate Sam on his role, or if you have any ideas you think would be useful to share, email him via youthchampion.scouts@rsgb.org.uk Lots of amateur radio stations are on the air this weekend and next weekend for World Thinking Day on the Air. Listen out for them and encourage the young Girlguiding members. You can find details of some of the active stations via rsgb.org/thinking-day but, if your station isn't listed, please share details on the RSGB social media channels. The event aims to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication. Have you visited the RSGB's British Science Week web pages yet? Two new worksheets have recently been added to inspire you to get involved and showcase amateur radio to new audiences. The activities were designed by the RSGB Outreach Team to fit in with this year's British Science Week theme of ‘Change and adapt'. If you'd like to deliver these activities to schools or youth groups, the Society has sample lesson plans, risk assessments and a guide to contacting your local school available on its website. Remember that British Science Week isn't just for younger audiences, it is open to all. If you're looking for ideas to get your friends and family involved or a local community group, go to rsgb.org/bsw and visit the British Science Week resources page. There is a wealth of ideas available, from looking at the history of radio communications to building a sustainable system using only solar panels. If you have an activity planned for British Science Week, let the RSGB know by emailing the RSGB British Science Week Coordinator, Ian Neal, M0KEO via bsw@rsgb.org.uk Details of events taking place will be shared on the Society's website. The deadline for the RSGB Construction Competition is Saturday the 1st of March, which means you have less than two weeks left to submit your entry. The judges will be considering entries in six categories: beginners, construction excellence, innovation, software, antennas and outreach. To find out how to submit your application go to rsgb.org/construction-competition The results of the competition will be announced during the 2025 RSGB Annual General Meeting on the 12th of April. If you are passionate about amateur radio and have some spare time to support fellow radio amateurs, why not become an RSGB District Representative? There are currently 12 vacancies across the United Kingdom, including in Belfast, Cambridgeshire and Lancashire. To find out if there is a vacancy in your region go to rsgb.org/volunteers and then get in touch with the Regional Representative of the district with the vacancy. Amateur radio operators are reminded to take care when operating on the WRC-15 secondary amateur allocation at 5MHz. The UK still has no access to the full WRC-15 allocation. Despite requests, this seems unlikely to change in the foreseeable future. Whilst the UK is fortunate to have more generous licence conditions, these mustn't be put at risk by irresponsible operating in violation of the licence conditions, particularly in the 5358 to 5362kHz gap where there is no UK allocation. The RSGB website has detailed advice for operators, both for SSB and digital modes, on its rsgb.org/5mhz web page. Please take care not to transmit outside of the UK segments even if you hear other amateurs transmitting. Remember that signals heard may be coming from amateurs in other countries with different allocations. The RSGB ARDF Committee is pleased to announce the return of the British ARDF Championships in 2025. The Championships will be held as a three-day festival in early April 2025. Entries open on the 1st of March and will remain open right up until the event itself. Further information and updates can be found at tinyurl.com/ARDF25 Please send details of all your news and events to radcom@rsgb.org.uk The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week. And now for details of rallies and events The Red Rose Winter Rally is due to take place on Sunday the 23rd of February from 10 am at Mather Hall, Mather Lane, Leigh, Lancashire, WN7 2PJ.

Using SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of February 2025 Two large coronal holes on the Sun's surface have been spraying solar material towards Earth, pushing the Kp index to a high of 4.67. The solar wind speed has been consistently higher than 500 kilometres per second and, with a south-pointing interplanetary magnetic field, the plasma has flooded into Earth's magnetic field. There have been a few aurora warnings, but these have only been minor. As a result, the ionosphere has not been too badly affected and daytime maximum usable frequencies over a 3,000km path have generally remained above 28MHz, with the odd dip towards 24MHz. Coronal mass ejections have not made an appearance and there were only three M-class flares between the 9th and 13th of February. Meanwhile, the solar flux index fell to the 150s and 160s last week. Recent HF DX has included the V73WW DXpedition on the Marshall Islands, which has been worked from the UK, including on the 40, 30 and 20m bands using CW. The TX7N DXpedition to Marquesas Island in French Polynesia has just finished. It wasn't an easy path, but it was worked from the UK on all bands from 30 to 12m using FT8, CW and SSB. Next week, NOAA predicts that the solar flux index could rise a little, to be in the 180 to 190 range. Once Earth is free from the effects of the current coronal hole stream, we may expect the Kp index to retreat, perhaps to a maximum of 2. So, DX next week could be quite reasonable but, as always, keep an eye on solarham.com for daily updates. And now the VHF and up propagation news from G3YLA and G4BAO The lingering high pressure just to the east of the UK is holding weather fronts over western Britain for the time being with any tropo benefits confined to eastern areas and being marginal at best. During the coming week, changes will be slow but gradually a more determined push on the Atlantic fronts may bring them over most areas, except the extreme southeast of the country. This will make rain scatter more accessible although the models suggest that the fronts are likely to become weaker. So, they will not be especially useful by the time they reach the southeast. Sporadic-E is in its quiet season now, as are the meteor scatter prospects, with no major showers in attendance until the spring Lyrids in late April. Perhaps this quieter time is a chance to do some operating housekeeping. For example, you could update a list of nearby repeaters and beacons to help you track developing openings. Or maybe you could consider trying a new mode or band. Perhaps you could learn to use digital modes for meteor scatter. Maybe consider joining the increasing numbers trying CW on the 2m band. Moon declination went negative again on Saturday the 15th and path losses are rising as the Moon moves away to apogee, its furthest point from Earth, on Tuesday the 18th. 144MHz sky noise is low for most of the coming week but goes high for the weekend of Saturday the 22nd. And that's all from the propagation team this week.
GB2RS News Sunday the 9th of February 2025 The news headlines: A new RSGB web page focuses on emerging technology An upcoming talk at Bletchley Park Museum aims to widen awareness of the radio spectrum and radio transmission Remember to share your British Science Week ideas The RSGB has launched a new web page on how emerging technology can be used in amateur radio. Technologies such as artificial intelligence and 3D printing offer the opportunity to broaden the definition of amateur radio. They can also increase appeal and attract a more diverse audience. For existing radio amateurs, they offer the opportunity for progression through learning new skills. You'll also find links to two RSGB Convention presentations, including the newly released talk on 3D printing by Tom Wardill, 2E0JJI. Go to rsgb.org/emerging-technology to learn more. The Society will be adding more technologies to the web page in the coming months and would love to hear from you if you are involved in amateur radio in any of these areas. Share your stories via comms@rsgb.org.uk On Saturday the 29th of March, the RSGB National Radio Centre Coordinator, Martyn Baker, G0GMB, together with Andy Webster, G7UHN from the Radio Communications Foundation, will be delivering a talk in the Fellowship Auditorium at the Bletchley Park Museum.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 5th of February 2025 Last week went pretty much as predicted. The solar wind from a large coronal hole impacted the Earth on Saturday the 1st of February, pushing the Kp index to four. The hole was so large that the geomagnetic disturbance lasted until the early evening on Sunday. Once the solar wind speed had dropped, things got back to normal and the Kp index has been in the range of 1 to 2 ever since. The event appeared to have had little effect on HF propagation, with maximum usable frequencies over a 3000km path remaining above 28MHz during the daylight hours. So it looks like we dodged a bullet. At the time of writing, we have had 21 M-class flares in three days. A solar flare measuring M8.8 was detected around active region 3981, peaking at 0358UTC on the 3rd of February. This was the strongest flare yet from this region in terms of peak X-Ray flux. However, the flare itself was impulsive and was not the source of a coronal mass ejection. Over the next week, NOAA predicts that the solar flux index could fall slightly to be in the 180 to 200 range. Make the most of the good propagation as we may be entering a period of unsettled geomagnetic conditions again from the 10th to the 17th of February. NOAA predicts that the Kp index could rise to a maximum of 5 on the 13th but is likely to be in the range of 3 to 5 over the seven days. Part of this may be down to another coronal hole which became Earth-facing on the 6th of February. There is also a good chance that we could get an X-class eruptive flare from active regions 3981 or 3978, which could result in a coronal mass ejection. We recommend you keep an eye on solarham.com for daily updates. And now the VHF and up propagation news from G3YLA and G4BAO High pressure during the second half of last week brought some useful tropo conditions. As this week, ending today the 9th comes to a close there are some wintry showers along North Sea coasts, which may produce some snow and rain scatter. However, this may be weakened by the nearby high pressure. By the end of this week, ending today the 9th, there will be a change of weather pattern as the high, having now migrated to Scandinavia, leaves room for Atlantic weather systems to encroach from the west during the coming week. This could bring rain scatter possibilities to the western side of the country. These should be more useful than the eastern coast ones at the end of last week since the rain will probably be heavier and the fronts slow-moving. This time of year is something of a desert for Sporadic-E propagation although look out for lesser events as a result of jet streams. You can track these on the Propquest website. Keep a look out for auroras during the week beginning tomorrow, the 10th. The likelihood of M-class flares is around 85%, while the chance of X-class flares is approximately 20%. So keep an eye on the Kp index for any potential solar events that could cause auroras. Next week, there are no major meteor showers. The next significant meteor shower, the Lyrids, will become active in April. Keep checking the pre-dawn period for random meteors. Moon declination reached a maximum yesterday, Saturday the 8th. Path losses are still low but will increase throughout the coming week. This means that this weekend, ending today the 9th, should produce good activity for EME, especially on the GHz bands with long Moon windows and high peak Moon elevation. 144MHz sky noise is moderate this weekend, ending today the 9th, but falls to low for the rest of the coming week. And that's all from the propagation team this week.
It's Friday, April 26th, A.D. 2024. This is The Worldview in 5 Minutes heard at www.TheWorldview.com. I'm Adam McManus. (Adam@TheWorldview.com) By Adam McManus Muslims set fire to Christians' homes in Egypt On Tuesday, April 23rd at 11:00 p.m., Islamic extremists set fire to several homes and shops owned by Coptic Orthodox Christians in Egypt's Minya Governorate, reports International Christian Concern. Shockingly, as the flames grew, the Muslims attempted to prevent the Christians from leaving their burning homes. Extremists later shared a video on social media showing Coptic homes on fire as a song, praising the attack, played in the background. The attack occurred after word spread that residents of the village, which is home to 3,000 Christian families, had obtained a permit to construct a church building. Some associated with the church received threats after the building permit was issued. Despite promises of safety from security forces, the cries of help from the archbishop and the local Coptic community went unanswered as the attack unfolded. Security forces arrived only after the attack, leaving a yet unknown number of Christians to perish in their burning homes. According to Open Doors, Egypt is the 38th most dangerous country worldwide in which to be a Christian. America to militarily withdraw from Niger, Africa Niger, Africa has demanded that the United States militarily withdraw from the country, reports CNN. In response, U.S. Deputy Secretary of State Kurt Campbell met with Niger's Prime Minister Ali Lamine Zeine on Friday to put those plans in motion. The major drawdown will significantly impact the U.S. troop presence on the continent of Africa. The move comes amid serious U.S. concerns about the country's deepening relationships with Russia and Iran. Haitian Prime Minister resigns Haiti's Prime Minister Ariel Henry resigned on Thursday as a new council was sworn in to lead the country gripped by deadly gang violence, reports the BBC. He agreed to step down last month after armed groups blocked his return to Haiti. Gangs now control most of Port-au-Prince, the capital. Teen suspended for “Only Two Genders” t-shirt A Catholic teenager has been suspended from his Ontario public high school for wearing a sweatshirt that said, “There are only two genders,” reports LifeSiteNews.com. Malachy O'Kane, age 16, was suspended on April 18, the second day he decided to wear his gender critical shirt to the Granite Ridge Education Centre in Sharbot Lake, a village near Kingston, Ontario. He was excluded from school for six days, beginning Friday, April 19. O'Kane was first told to remove his shirt by the school's vice-principal, Wojtek Czermak, after the teenager was called out of his classroom about 30 minutes after the school day began. When the student asked what the problem was, a school counselor said, “It's considered hate speech.” In Genesis 1:27, the Bible says, “So God created man in His own image, in the image of God He created him; male and female He created them.” Harvey Weinstein's rape conviction is overturned Yesterday, New York's highest court threw out Harvey Weinstein's 2020 rape conviction because the trial judge unfairly allowed testimony against Weinstein based on allegations that were not part of the case, reports The Associated Press. The ruling shocked and disappointed women who celebrated historic gains during the #MeToo era and left those who testified in the case bracing for a retrial against the ex-movie mogul. Weinstein, age 72, will remain in prison because he was convicted in Los Angeles in 2022 of another rape. But the New York ruling reopens a painful chapter in America's reckoning with sexual misconduct by powerful figures — an era that began in 2017 with a flood of allegations against Weinstein. Youth need (1) the truth and (2) connection to intergenerational relationships John Stonestreet, president of the Colson Center for Christian Worldview, warned an audience that young people today are "untethered" from the truth and disconnected from meaning and purpose, reports The Christian Post. Last month at City Church in Chattanooga, Tennessee, he said, “Students today, just quite simply, need two things. They need, first of all, to hear the truth. … We live in a world that's detached itself from the source [of truth]." Stonestreet quoted a British survey conducted over a decade, which found that initially, 13 years ago, 90% of young people, aged 18-28, believed that life had meaning. However, when the same question was asked 10 years later, only 10% of respondents reportedly felt that life had meaning. He said, "There's never been a generation so untethered from God. Even in generations past, when we fooled around with ideas about whether God exists or not, we still lived in a culture where family was the norm and largely stable.” According to Stonestreet, the solution is the reintroduction of truth through intergenerational relationships and mentoring. God's meteor shower And finally, every year from April 15 to April 29, dozens of shooting stars streak through the sky in this spectacular show from God, reports Business Insider. The Lyrid meteor shower is in full swing this week. Unfortunately, the bright supermoon could make it harder to see it. The meteor shower was most active from Sunday night to Monday morning, but it will remain visible for the next week. In the Northern Hemisphere, the best time to see the Lyrids is during the early morning hours after the moon sets and before the sun rises.

GB2RS News Sunday the 28th of April 2024 The news headlines: New mock papers for amateur radio licence exams have been published A revised amateur radio examination syllabus has been released The RSGB has released the video review of 2023 by its President John McCullagh, GI4BWM The RSGB Exam Syllabus Review Group has published a new set of mock papers covering each of the amateur radio licence exams, from Foundation through to Direct to Full. These papers are in addition to those already available. They are each marked as ‘mock exam paper 3' and you can find them on the RSGB website at rsgb.org/mock-exams The new amateur radio licence has now been in effect for a few weeks. Changes to the licence conditions have made it necessary to revise the examination syllabus. The RSGB is pleased to release version 1.6 of the syllabus which includes these revisions. Compared to version 1.5 in current use, the only section that has seen major changes is Section 1 – “Licensing and station identification”. In Section 7 – “Operating practices and procedures” – there were some minor changes, for example regarding suffixes. Exams will start using version 1.6 of the syllabus on the 1st of September 2024. The Society has released the video review of 2023 by RSGB President John McCullagh, GI4BWM. Filmed at the Ofcom Spectrum Management Centre near Baldock in Hertfordshire, the video covers a wide range of very positive activities, events and achievements. The President also talks about the RSGB's strategic priorities, gaining publicity in the mainstream media, and the important work done by the Society on behalf of all radio amateurs to protect the spectrum. One example is the WRC Conference, where the RSGB Microwave Manager Barry Lewis, G4SJH, led the IARU team responsible for defending amateur use of the 23cm band. You can watch the video on the RSGB YouTube channel at youtube.com/theRSGB At the April Regional Forum meeting, Regional Representative 10, Keith Bird, G4JED was elected as Chair, and Regional Representative 3, Martyn Bell, M0TEB was elected as Secretary.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of April 2024 We had another week with plenty of sunspots, and HF conditions were quite good in the second half. Earlier, the Kp index reached 3 and 4, which didn't help maximum useable frequencies, or MUFs for short. For example, on Sunday the 21st, the Kp index rose to 4 and the MUF over a 3,000km path remained stubbornly below 21MHz until later in the morning. This could have been due to a coronal hole on the Sun's equator, which added to the solar wind. By Wednesday, conditions were nearly back to normal, with a Kp index below 2 and an MUF of more than 24MHz. By Thursday the improvement had continued, giving us an MUF of more than 28MHz by 0900UTC. There have been many reports of 10m band DX being worked, including Sebastien, FK4AX and Pat, FK8HA in New Caledonia in the Pacific on SSB. Sebastien has just got his licence and is keen to work DX from the UK. This shows that it is worth keeping an eye on the CW and SSB portions of the 10m band, which can often throw up surprises. Next week, NOAA predicts that the solar flux index will decline to around 160. The Kp index is predicted to be around 2 to 3, but that may be wishful thinking. With 16 active regions visible on the Sun's surface on Thursday, anything could happen. Only minor C- and M-class flares have occurred recently but, as we always say, it wouldn't take much for those to turn into X-class events. So, make the most of quiet geomagnetic conditions when we have them as, by the time you read or hear this, we could once again have very unsettled conditions indeed. And now the VHF and up propagation news from G3YLA and G4BAO The cold, unsettled weather will ease its grip over the last few days of this week, ending the 28th of April, but only because the whole area of low pressure is moving across the country this weekend. Low pressure remains close by for much of the following week and only a hesitant return of high pressure west of Ireland will improve things for western Britain at the end of the week. The result is a chance of Tropo for western Britain next week, but it will probably be of limited quality since it is likely to form in cold, dry air across any temperature inversion. The remaining option in such weather patterns is primarily rain scatter for those on the GHz bands. The many online weather radar displays can be used to highlight the areas of heaviest rain. We are past the peak of the Lyrids meteor shower, but the Eta-Aquarids, with a Zenithal Hourly Rate of 50, peaks next Sunday the 5th around 2100UTC. Until then, rely upon random activity which tends to be better around dawn. The Sun has been more active again recently, so monitor the clusters and Kp index for signs of geomagnetic activity and the chance of an aurora if the Kp index exceeds 5. Sporadic-E tends to produce a few early examples in May ahead of its June peak. Check the DX clusters during the late afternoon or early evening as openings can be very brief early in the season. Start on the 10m band and, if short skip within Europe is present, move up to the 6m band. Digital modes are more sensitive so check FT8 reports to give clues as to where the chances are greatest. For EME operators, the Moon is at minimum declination today, Sunday the 28th, meaning we'll have short Moon windows to start the coming week. Path losses are falling but perigee, when the Moon is at its closest point, is still over a week away. 144MHz sky noise is high this weekend, ending the 28th of April, but falls too low by the end of the coming week. And that's all from the propagation team this week.
Earth is passing through the dust stream that produces the April Lyrid meteor shower this week. There are sometimes bright fireballs. The full moon is interfering though.

On Wednesday the 17th, the 80m Club Championship runs from 1900 to 2030UTC. Using SSB on the 80m band, the exchange is signal report and serial number. On Thursday the 18th, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using All modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of April 2024 The Sun is still looking a little bare, but the solar flux index has climbed back to 131, as of Thursday the 11th, with four active regions. The promise is that things will improve, especially as we will soon see the return of active region 3615, which was the source of numerous M-class and one X-class flare on its last rotation. Things have been a little sparse on the higher HF bands, with only FT8 being audible or visible on the 10m band at times. Having said that there has been some good FT8 DX to be worked on the 10m band, including Angola, Malawi, China, Japan, Taiwan and the Solomon Islands. During the recent solar eclipse event there were also a lot of US stations on the 10m band using WSPR. These included Bob, K6XX in Santa Cruz, California, who was copiable in the UK at around 1850UTC. This just shows how effective WSPR is as a mode on an otherwise quiet band. There have been some early signs of Sporadic-E on the 10m band using digital modes, including some brief openings to Scotland from eastern UK. We can expect these to improve as we head towards May. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range with a maximum Kp index of three. If this is correct it means that HF conditions will be roughly the same as last week. And now the VHF and up propagation news from G3YLA and G4BAO The weather patterns are showing signs of change after being stuck for quite some time, and the main beneficiary will be VHF operators seeing a chance of Tropo returning to the bands. The initial unsettled weather over the UK, with high pressure fixed over the continent, will take us through to the middle of the coming week. Thereafter, a high will develop to the southwest of Britain midweek and drift northeast across the country, although some models take the high on a more southerly track. In either event, there should be some useful Tropo in the south and possibly northern areas too. This may be limited to southwestern areas for Tuesday's 23cm UK Activity Contest, but will hopefully be more supportive of the 4m UK Activity Contest on Thursday. Meteor scatter is worth a look next week since we are approaching the 21st and 22nd of April peak of the Lyrids shower at the end of next weekend. The quieter solar conditions have taken aurora down the table, but it's still good practice to watch out for if the Kp index goes above five. Gigahertz-band rain scatter certainly drops down the league table next week as high pressure probably takes over. As we said earlier, the next big thing is the start of the 2024 Sporadic-E season, which slowly comes to life during April for the 10 and 6m bands, especially on digital modes, whereas the real shift up in gear often comes during May. As mentioned last week, it's worth updating your list of beacons in your rig's memory while it's still quiet. For EME operators, Moon declination is at maximum this weekend, ending the 14th, so there will be long Moon windows. We are past perigee, so path losses are rising again. 144MHz sky noise is moderate this weekend then low for the rest of the week. And that's all from the propagation team this week.

New evidence from NASA's Curiosity rover, detailed in the journal Geology, suggests that underground water may have been present in the crater during the latter part of the Hesperian period, 3.7 to 3 billion years ago. This discovery, marked by deformed desert sandstone, hints at a more habitable past and could reshape our search for ancient Martian life.*The Sun's Spectacular Double Solar FlareThe Sun has unleashed its most powerful eruption since 2017 with a double solar flare event, signaling a ramp-up towards solar maximum. The X1.1-class flare, coupled with a series of M-class flares, has sparked vivid auroral displays and heightened space weather activity. This dynamic solar performance, captured by ESA's SMOS and Swarm satellites, underscores the Sun's influence on Earth's magnetosphere and the importance of real-time space weather monitoring.*The SR-71 Blackbird's Alleged Successor: The SR-72Rumors persist of the Pentagon's development of a hypersonic aircraft, the SR-72, potentially succeeding the legendary SR-71 Blackbird. Reports suggest that Lockheed Martin's Skunk Works is behind this classified project, which could reach Mach 6 speeds and revolutionize reconnaissance with its unmanned design. If true, this aircraft could redefine the boundaries of aviation and surveillance technology.*April Night Skies: Alpha Centauri to the Lyrids Meteor ShowerAs autumn's grip tightens, the night skies of April offer a celestial tapestry rich with wonders. From the Southern Cross standing upright to the nearest star system, Alpha Centauri, being prominently on display, stargazers have much to explore.

GB2RS News Sunday the 17th of March 2024 The news headlines: The RSGB's 2024 AGM is coming up British Science Week is drawing to a close Changes to examination fees are coming soon This year's RSGB AGM will take place at 10 am on Saturday the 13th of April and will be held online to ensure as many members as possible can watch and take part. The formal business of the meeting will include the results of members' votes on the resolutions, including the endorsement of three Nominated Directors. The President will give a video review of 2023 and the Society will announce the recipients of its annual awards and trophies, as well as the winners of its construction competition. At the end of the meeting, there will be a recorded presentation on “Making amateur radio licensing fit for the future” by Ofcom Group Director, Spectrum, David Willis. This will be followed by a live Q&A on the new licence conditions, with four senior RSGB representatives answering your questions: President, John McCullagh, GI4BWM; Board Chair, Stewart Bryant, G3YSX; General Manager, Steve Thomas, M1ACB; and Spectrum Forum Chair, Murray Niman, G6JYB. You can find more information about the candidates, voting and how to ask the Board a question on the RSGB AGM web pages at rsgb.org/agm British Science Week is drawing to a close and lots of exciting activities have been going on. Radio amateurs across the country have been encouraging young people to explore and understand our hobby and there have been some wonderful ways of incorporating the theme of “Time” into amateur radio activities. The RSGB would like to thank those who have shared ideas and resources, promoting the magic of radio communications with young people. There will be a report in the June issue of RadCom to showcase the activities that have happened and to inspire people to get involved next year! Perhaps you ran a construction day, set up and operated a radio station in a school or achieved a QSO with GB3RS at the RSGB National Radio Centre. Whatever you've been doing, please send your reports, with separate high-resolution photographs, to radcom@rsgb.org.uk by the 21st of April 2024. The RSGB would welcome feedback about what worked well, what you learned and how the Society could develop its British Science Week activities next year. Please email the RSGB British Science Week Coordinator Ian Neal, M0KEO at bsw@rsgb.org.uk to share your thoughts. Early in February the RSGB announced that the fees for Foundation, Intermediate and Full level examinations would increase from the 1st of May 2024. You can now use the online booking system to book an exam before the 1st of May at the current price or select exam dates from the 1st of May at the new prices. Please ensure you make the correct date selection, as booking errors that need to be changed may incur an administration fee as outlined in the exam terms and conditions. To book an exam, go to the Student Information section of the RSGB website and choose the option to book and pay for your exam from the right hand menu. The RadCom Contesting column has new editors! The RSGB Contest Committees will be overseeing the column and have planned a schedule of topics. Some will be written by members of the three contesting committees, and some by others who can share their experiences. As well as information about various aspects of contesting, the committees hope that the column will feature a contesting tip of the month, a featured UK contester, as well as a contest of the month. Once each issue is published, the column content will be shared on the RSGB website to provide a useful resource about contesting. You can see a list of the planned topics at rsgb.org/radcom-contesting The committees are keen to hear from people who would like to be involved, so if you would like to suggest a missing topic or offer to write something for the column, please email ContestClub@rsgbcc.org And now for details of rallies and events Callington Radio and Electronics Rally is taking place today, the 17th.

Using all modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of March 2024 What a difference a month makes. We've gone from a solar flux index up to almost 200, to one that is down in the 120s. Over the past week, we have had only two M-class solar flares, which means we have had limited coronal mass ejection activity and therefore low Kp indices. Last weekend's Commonwealth Contest saw UK amateurs making plenty of HF contacts, some with Australia, but everyone agreed that HF propagation was a little lacklustre. There is a daily chance of moderate-class solar flares from AR 3607, the largest sunspot region, but all remaining spots remain mostly small and simple. The solar wind speed has been quite high with sporadic periods of a south-pointing Bz field. This is what has pushed the Kp index to three, but this isn't a big threat to HF. There is a slight chance of unsettled intervals caused by a weak coronal hole near the south centre of the solar disc coupled with the fast solar wind. NOAA reports that active region 3590 has been detected on the far side of the Sun using helioseismology. This may mean that it will still be active and a threat when it returns in a week or so. This region was the source of the X6 solar flare on the 22nd of February – the largest so far in solar cycle 25. Next week, commencing the 18th of March, NOAA predicts that the solar flux index will remain in the 120 to 130 range, although the US Air Force predicts it could reach 150. Geomagnetic conditions are likely to be mainly settled with a maximum Kp index of two or three. So, this is a reasonable forecast for HF propagation, which should remain open up to 28MHz during daylight hours. This is also a good time for north-south paths, such as the UK to South Africa, and the UK to South America. And now the VHF and up propagation news from G3YLA and G4BAO The continuing theme of unsettled weather will produce further spells of rain and heavy showers and once again provide some rain scatter options on the GHz bands. Another thing to mention is that, as we move towards the latter part of the month, the intensity of showers becomes greater due to the additional warmth improving the effectiveness of the rain scatter process. It is very hard to find any traditional Tropo until we get well into the coming week. It may occur on Thursday the 21st when a high will develop a ridge from Biscay across southern Britain and the near continent. This should provide a chance of Tropo for the final few days of the coming week. Unfortunately, this is not in time for the UK Activity Contest on 1.3GHz on Tuesday the 19th, but the 70MHz UK Activity Contest on Thursday the 21st may be luckier. The north of Britain may start to see the next low bringing rain over that weekend, so although it has an early exit from any Tropo, at least being well north gives Scottish stations a head start for any aurora, which tends to favour the spring months. Meteor scatter remains in the random territory – try just before sunrise for best results. But with the next major shower being the Lyrids in late April, we have a while to wait for an uptick in activity. Lastly, a brief mention of Sporadic-E. It has popped up with some weak events on the Dourbes plots on Propquest, but the main season is still a little way off. Maybe check next month for a heads-up on the lower bands like 28 and 50MHz. Of course, digital modes will get a head start, so best to check the clusters and chatrooms for signs of fleeting activity. Some UK stations reported 50MHz trans-equatorial propagation to Africa last week, so check for that. For EME operators, Moon declination reaches a maximum on Sunday, but path losses are starting to increase again. 144MHz sky noise is moderate, falling to low on Wednesday. And that's all from the propagation team this week.
GB2RS News Sunday the 14th of January 2024 The news headlines: RSGB releases new video about changes to amateur radio licensing WRTC 2026 team to appear in an RSGB Tonight@8 webinar Paul Athersmith, M0PLA achieves Mountain Goat award Following Ofcom's consultation on the amateur radio licence last year, it released a statement in December 2023. The statement outlined its decision to update the amateur radio licensing framework to ensure the policies and licences meet the needs of today's and tomorrow's radio amateurs while streamlining the licensing process. It also published a General Notice, giving notice of its proposal to vary all amateur radio licences. The RSGB has just released a video in which RSGB General Manager Steve Thomas, M1ACB chats to RSGB Spectrum Forum Chair Murray Niman, G6JYB. Murray recaps some of the headline results of the Ofcom consultation, including where changes have occurred to Ofcom's proposals. They also talk about what this could mean for radio amateurs in the future. This is a great example of how the RSGB is working not only to defend the spectrum but also to support all radio amateurs to understand and make use of the privileges they enjoy through their amateur radio licence. You can watch this video on the RSGB's YouTube channel or via the Society's licence review updates page at rsgb.org/licencereview On Monday the 15th of January, join the RSGB's first Tonight@8 live webinar of 2024.

The UK Six Metre Group Winter Marathon began on Friday the 1st of December 2023. The contest will run until the 31st of January 2024. Using all modes on the 6m band, the exchange is signal report and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of January 2024 We couldn't have asked for better solar conditions last week. We had a low Kp index that never got any higher than 2.67, and a solar flux index that started the week at 167 and then rose to 186 by Wednesday. So, at first glance, this looks like ideal conditions for HF. However, we are in the middle of winter and therefore the ionosphere is not at its best. The low bands are also being affected by the higher solar flux and, on the whole, the 14MHz band and above are closing as the night draws in. Daytime critical frequencies remain around 9 to 10MHz, so the 40m band should remain useful for inter-UK work. Nighttime critical frequencies are currently falling to 3.5 to 4.5MHz, which means the 40m band is only open to long skip, if at all. The critical frequency is the highest that still returns a signal from the ionosphere if sent straight up, and is a good guide as to which bands are open to near vertical incidence skywave or NVIS signals around the UK. On the brighter side, 14MHz has been showing signs of DX. The VK6RBP beacon has been heard on 14.100MHz in the afternoon via the short path and 28.200MHz in the morning via the long path. The 12m band has shown international beacons RR90 in Siberia, OH2B in Finland, LU4AA in Argentina and YV5B in Venezuela, on 24.930MHz in the morning. While the 10m band also highlighted YV5B in Venezuela during mid-morning. Not a massive catch, but better than we were getting two years ago! For the coming week, NOAA predicts that the solar flux index may fall into the range of 150 to 165. Geomagnetic conditions are predicted to remain settled with a maximum Kp index of 2. As always, this could easily change if we have a coronal mass ejection, so keep an eye on solarham.net for near real-time solar conditions. And now the VHF and up propagation news from G3YLA and G4BAO The area of high pressure has been working well for some parts of the country, with Tropo conditions lasting into the start of this weekend, but as a cold front moves South on Saturday the 13th, all will change as the high becomes displaced to the Atlantic. Therefore, there is no significant Tropo for the coming week, but there may be some rain scatter from showers, especially around the coasts. We seem to have passed the period of unusual winter Sporadic-E propagation without much evidence of activity so that just leaves meteor scatter. After the Quadrantids last week, we entered a period of low meteor shower activity, leaving just random meteors until the next major shower, the Lyrids in April. For random meteor scatter, the pre-dawn period works best. The solar conditions can still be instrumental in producing extra propagation treats with chance aurora. Probably the best operating policy is to monitor the geomagnetic Kp-index with high values greater than 6 being a good sign for VHF. For EME operators, this week starts with very low Moon declination, low peak Moon elevation and short Moon windows, but declination is rising and goes positive again on Tuesday. Path losses are still low and reached minimum at perigee on Saturday the 13th. 144MHz sky noise is low for all of the coming week. And that's all from the propagation team this week.
We had a new moon earlier this week, on April 20. So, with the darkened night sky, it is a good time to do some stargazing. Plus, we have the Lyrids Meteor Shower running through April 25.
A meteor shower that's been around for at least 2700 years is at its best the next couple of nights. It's best viewed between about midnight and dawn. And the Moon sets early, so it won't interfere with the sparklers. The Lyrid shower was first recorded by Chinese astronomers in 687 BC. That's farther back than any other current shower. Over the centuries, showers come and go. They're produced by tiny grains of rock and dirt shed by comets or asteroids. That debris spreads out along the parent body's orbital path. Earth flies through this path every April. The particles ram into our atmosphere at more than a hundred thousand miles per hour. They vaporize, forming the glowing streaks of light known as meteors or shooting stars. But meteor showers don't last forever. The orbits of Earth and the parent comets and asteroids naturally move out of sync. In addition, the comets and asteroids can be pushed around by the gravity of Jupiter and other planets. That changes their paths. So over time, meteor showers come and go. But the Lyrids have stuck around longer than any other shower yet recorded. The Lyrids are named for Lyra, the harp. That's because the meteors all appear to “rain” into the sky from near the constellation's brightest star, Vega. They can zip across any part of the sky, though, so you don't need to look at Lyra to see them. But the view is best after Lyra rises to prominence, around midnight.

Chris isn't disheartened by a sucker zone, and Mr Max is on the trail of the missing bone. Meanwhile we talk about meteors, with the first decent shower of the year due this weekend, and learn how they help astronomers study the distant Universe.

GB2RS News Sunday the 23rd of April 2023 The news headlines: RSGB Coronation activities RSGB AGM announcements and videos RSGB Board Chair The RSGB is delighted that Ofcom has confirmed that the callsign GB23C can be used for the RSGB's Coronation Special Special Event Station. Cray Valley Radio Society members led by Bob, M0MCV and Dave, G4BUO are organising the flagship amateur radio station that will use this callsign from the 3rd to the 8th of May. The Special Special Event Station will be on the grounds of the Old Royal Naval College, along the riverside in Greenwich. From the 10th of May onwards, the callsign will be available for individuals and clubs to use until the end of June 2023, and further details about this will be announced shortly. Ofcom has also kindly agreed to a block of 676 Special Special Event Station callsigns for the RSGB's Be a Connect activity for the Coronation. These are GB23BAA to BZZ, which will be available throughout May and June. More details on how to obtain one of these will be given next week, but meanwhile, you may wish to find a beacon site you could activate one or more times for this event. Finally, if you are planning outreach activities with local clubs and groups, take a look at the paper circuit template the RSGB has just shared on its website – go to rsgb.org/coronation and choose the coronation activity ideas tab in the right-hand menu. The RSGB's AGM was held online last Saturday, the 15th of April. If you missed the live event, you can see the results of the elections and follow links to the trophy awards and the construction competition winners on the RSGB website via rsgb.org/agm. You can also catch up on the full live stream or watch individual sections on the Society's YouTube channel. The RSGB has released separate videos of the outgoing President's review of 2022, its new short Convention promo, and the interesting presentation about preparing the GB2RS propagation reports by the RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. You can see them all in the RSGB 2023 AGM playlist on YouTube via youtube.com/theRSGB Following the RSGB AGM on Saturday the 15th of April, a brief Board meeting was held to consider necessary appointments. The Board was aware that Stewart Bryant, G3YSX, who had been in a dual role since the recent resignation of Richard Horton, G4AOJ, had expressed a willingness to continue as Chair if required. It was agreed that Stewart should be co-opted to the Board under the terms of Article 37 and was asked to join the meeting. Stewart was then elected unanimously to serve as RSGB Board Chair until the 2024 AGM. This a reminder now that SOS Radio Week 2023 starts at midnight on the 1st of May and concludes at midnight on the 31st of May. It is an opportunity to support the many voluntary organisations in the British Isles whose members volunteer to save the lives of others at risk around the many miles of its coastline, and out at sea. These organisations include the Royal National Lifeboat Institution, the National Coastwatch Association and numerous independent lifeboat and coastal rescue groups. Individual amateur radio operators and clubs are invited to register to become an official SOS Radio Week station and operate under their own callsign, their club's or a special event callsign to raise awareness of the great work these volunteers perform. Awards are available for registered stations that make the most contacts on each of the 160m to 70cm bands and using various modes.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of April 2023 We had a surge in sunspot activity over the last week, pushing the solar flux index up to a maximum of 178, although it subsequently declined to 147. Solar flare activity was quite subdued after a frantic period from the 13th to the 15th that saw 40 C-class flares and two M-class flares erupt. This activity was mostly centred around active region 3282 in the northwest quadrant. Geomagnetic conditions were unsettled for a time around the 18th and 19th with the Kp index hitting a maximum of 4.3. This appears to have been due to enhanced activity from a coronal mass ejection and continuing coronal hole activity that saw the solar wind speed hit more than 600km/s and the Bz swing south. The critical frequency was down below 7MHz on the morning of Wednesday the 19th, which impacted near-vertical incidence skywave signals around the UK. This impacted maximum useable frequencies, which struggled to exceed 21MHz over a 3,000km path on Wednesday, although by Thursday they were back over 28MHz again. A critical frequency of more than 10MHz meant the 40m band was once again suitable for close-in contacts around the UK. There were many reports of DX being worked later on during the week, with Australia and New Zealand topping the bill on 18MHz and 28MHz. Next week NOAA has put a more positive spin on sunspot activity. The Solar Flux Index is predicted to be in the range of 168 to 172 for the first half of the week, falling to around 160 in the second half. But we could be in for a bumpy ride geomagnetically, with the Kp index predicted to hit five on Wednesday the 26th of April through to Monday the 1st of May. This may be due to the return of solar phenomena that occurred 27 days ago and saw the Kp index get up to 4.67. Meanwhile, a very large solar coronal hole, albeit positioned very south on the Sun's surface, and a much smaller one on its equator, threaten HF conditions this weekend. Keep an eye on the real-time solar wind from the ACE spacecraft for signs of a rise in speed and a southward-pointing Bz interplanetary magnetic field on solarham.net. This could push to Kp index higher, perhaps to four. And now the VHF and up propagation news The Sporadic-E season is nearly upon us. Remember it will usually activate on 28MHz and then higher bands will follow if the event intensifies. There have been some 50MHz FT8 paths flagged up on DXmaps.com, although some may have been tropo. The recent large high pressure centred over Scandinavia has been a bit subdued as regards Tropo. Much of the time, the air nearer the surface has been fairly dry with little sign of banks of sea fog over the North Sea, which would suggest better ducting potential. We are now entering a phase with low pressure on the charts, initially over the south of Britain, but edging north for a time before drifting out across the North Sea. This could produce some rain scatter on the GHz bands, especially should any heavy April showers develop. Early next week a ridge will edge south across the UK in a colder northerly weather pattern, so although high-pressure returns, it may not be especially good for tropo. The third changeover comes after midweek when a milder south-westerly returns with active fronts bringing rain and unsettled weather, especially to the north and west. This could mean further opportunities for rain scatter on the GHz bands and perhaps a hint of tropo in the Southeast towards the continent. Aurora and meteor scatter are well worth considering, and the Lyrids shower peaks on Sunday the 23rd. The message is to monitor meteor scatter frequencies and the clusters for signs of activity and, of course, try putting out a CQ call! Moon declination is positive and rising, meaning increasing Moon time and increasing peak elevation until peak declination on Tuesday. Moon apogee is next Friday so path losses increase all week. 144MHz sky noise is moderate to low. And that's all from the propagation team this week.

GB2RS News Sunday the 16th of April 2023 The news headlines: Nominated Board Director Vacancy Regional Forum Facebook pages SOS Radio Week If you are an RSGB Member you still have time to apply for the RSGB Nominated Board Director vacancy. The RSGB needs a strong and effective Board and this could be your opportunity to be part of that. The deadline for applications is Monday the 17th of April. To find out more, go to the volunteer vacancies section of the RSGB website at rsgb.org/volunteers or, for an informal discussion, please email Nominations Committee Chair Stephen Purser, GW4SHF at nominations.chair@rsgb.org.uk The RSGB Regional Forum has created Facebook pages for each of the 13 regions. These pages focus on regional amateur radio communities and are moderated by members of the RSGB Regional Team. Whilst the pages share a similar style, they are very different in content. Selected posts are created by the RSGB moderators to maintain some news content from the RSGB, but the main content comes from clubs, individual licensees and also event organisers in those regions. The pages also provide a forum where anyone can ask for help with any part of the hobby. Clubs are positively encouraged to post news and events on the pages. You can find them on Facebook by searching for ‘RSGB Region' and the number of your local region, for example, ‘RSGB Region 1'. SOS Radio Week 2023 starts at midnight on the 1st of May and concludes at midnight on the 31st of May. It is an opportunity to support the many voluntary organisations in the British Isles whose members volunteer to save the lives of others at risk around the many miles of its coastline, and out at sea. These organisations include the Royal National Lifeboat Institution, the National Coastwatch Association and numerous independent lifeboat and coastal rescue groups. Individual amateur radio operators and clubs are invited to register to become an official SOS Radio Week station and operate under their own callsign, their club's or a special event callsign to raise awareness of the great work these volunteers perform. Awards are available for registered stations that make the most contacts on each of the 160m to 70cm bands and using various modes. Registration is now open and further details can be found at sosradioweek.org.uk The outgoing RSGB President Stewart Bryant, G3YSX and the incoming RGSB President John McCullagh, GI4BWM will be at the NARSA rally in Blackpool on Sunday the 23rd of April.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of April 2023 A news item this week suggested that the peak of solar cycle 25 could be coming earlier than expected. According to a paper in Frontiers in Astronomy and Space Sciences, by solar scientist Dr Scott Macintosh, the solar maximum may now be coming between late 2023 and mid-2024. So, make the most of the higher Solar Flux Index now! Solar activity picked up nicely over the past week. The solar flux index rose to 154 and there were eight active regions on the Sun's visible face by Thursday the 13th. Nevertheless, daytime maximum usable frequencies, or MUFs, remain down a little, which has probably more to do with seasonal ionospheric changes than reduced sunspot activity. As we head towards Summer we will see the daytime F2-layer MUF decline further before it picks up again in the Autumn. We also saw some M- and C-class solar flare action this week, but this was not really enough to cause serious problems to the ionosphere. Next week NOAA predicts the Solar Flux Index will continue to increase, perhaps peaking at 160 around the 16th to 18th of April. Unsettled geomagnetic conditions are forecast for the 18th, perhaps with the Kp index rising to four. The forecast for International Marconi Day on the 22nd of April is for a Solar Flux Index of 155 and a declining Kp index of three, which bodes quite well for the event. In all, the Solar Flux Index is expected to be in the range of 140 to 160 for the rest of the month. And now the VHF and up propagation news A big contrast is coming next week, so it's time to dust off the VHF gear again! The unsettled weather of this last week will make a complete swap over to more settled high-pressure systems next week. Initially, on Sunday this will appear as a ridge over the North Sea from a large high over Scandinavia. This will then gradually extend across the country and will eventually be joined by a second high west of Britain. The end result will be enhanced Tropo prospects in the coming week and potentially good conditions for the 23cm UK Activity Contest on Tuesday the 18th and the 4m UK Activity on Thursday the 20th. Those who enjoy rain scatter propagation in this current showery weather will have to look for other modes by Sunday, once the high pressure builds. As we are coming out of the Winter lull in meteor shower activity, with the medium-rate Lyrids peaking on the 23rd of April at 0100UTC with a Zenithal Hourly Rate, or ZHR, in the 20s, it's well worth a look for meteor scatter contacts. The end of April normally prompts a return of isolated Sporadic-E reports on the 10m band and perhaps even with data modes on 6m. The upper troposphere jet stream charts suggest it's got some potential, especially between Mediterranean countries although not quite so positive for paths nearer to home. The solar conditions may continue to offer a random chance of some aurora, so remember to keep an eye on the Kp index if it goes above five. For EME operators, the Moon perigee is on Sunday so path losses are at their lowest. Moon declination is rising, going positive on Tuesday meaning increasing Moon time and increasing peak elevation passes. 144MHz sky noise is low, but the Moon is close to the Sun on Wednesday and Thursday meaning high Sun noise for those days. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of April 2023 Solar activity declined this past week with the Sun looking distinctly spotless, other than active region 3270. In fact, this has even prompted some amateurs to question whether we are now past solar maximum for this cycle. Rest assured, we shouldn't be, as it is pretty common for cycles to ebb and flow as they develop. Having said that, half of the Sun's face is currently spotless, and NOAA predicts that the solar flux index will be in the range of 110 to 130 next week. Geomagnetically, things have been reasonably settled with the Kp index reaching a maximum of 4.67 over the past seven days. NOAA predicts that it could rise to four on the 10th and 11th of April but will otherwise stay pretty much as it is in the range of two to three. This may be due to a coronal hole that is currently making its way across the Sun's face in a near-equatorial position. However, we may not have seen the last of the activity from active region 3270, which has increased in both size and magnetic complexity during the past 48 hours and could soon produce a moderate M-Flare. But, if you are reading or hearing this on Sunday, the region will be moving out of sight and is therefore no longer a threat. Daytime F2 critical frequencies at midday remain around 9 to 10MHz giving a maximum useable frequency, over a 3,000km path, of just over 28MHz. If 10m isn't doing it for you we suggest moving down to 12 or 15m. Night-time F-layer critical frequencies are around 3 to 5MHz meaning MUFs over 3,000km are below 14MHz, leaving 3.5, 7 and 10MHz as the best bets for nocturnal DX. And now the VHF and up propagation news The current spell of high-pressure weather with enhanced Tropo, which turned up in time for the 2m UK Activity Contest on the 4th of April, is looking a bit vulnerable as active weather fronts come in from the Atlantic. We are likely to have a brief change to unsettled conditions weather-wise before the start of the Easter weekend and again see some rain scatter opportunities on the GHz bands. Scandinavian highs are often long-lasting at this time of the year and this high will regain control by Good Friday and should dominate over the UK during the Easter weekend to give some useful tropo possibilities again. However, quite early next week a new powerful Atlantic jet stream pushes into northern France and will bring a return of unsettled weather and perhaps more rain scatter. The Sporadic-E season is approaching and the higher HF bands like 10m can show good examples of Es, even during the second half of April, so a good chance to get into the habit of checking your ‘go to' list of 10m beacons as recently updated by Steve, G0KYA, on the propagation section of the RSGB website. The other defaults of auroral propagation have had a good run recently and random meteor scatter could also prove fruitful as we are soon ending the early year ‘drought' of meteor showers with the arrival of the Lyrids later this month. For EME operators, Moon declination is negative and falling, reaching its minimum next Wednesday. Moon time will be limited to low-elevation passes, but with low path losses as we approach perigee on the 16th. 144MHz sky noise is increasing to a high of more than 2,000 Kelvin next Wednesday before falling back to the mid-200s the following Sunday. And that's all from the propagation team this week.
The 365 Days of Astronomy, the daily podcast of the International Year of Astronomy 2009
Welcome to Observing With Webb, where a high school astronomy teacher tells you what you're looking at, why it's so cool, and what you should check out later this month…at night. Venus shines bright all month, Mercury makes a 3 week appearance, Mars hangs out with Gemini, Saturn continues its morning planet season, and the Lyrids have excellent observing conditions. April 22nd: LYRID METEOR SHOWER – At only 10-20 meteors per hour, it is a minor shower, but we have essentially no Moon to get in the way of the best observing. The shower is greatest on the 22nd, but you might see some on the 21st and 23rd as well. Just remember each meteor is piece of debris left over from a comet, and we're crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. The best viewing is between 2am and 4:30am, but you never know when you'll see something awesome. Some advice for watching: - Find a dark location and lie down in a reclining chair or something that insulates you from the ground. - Check the weather to see if the skies will be clear. - Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something. - If you're feeling extra nerdy, do a scientific meteor count (S&T and IMO)!

GB2RS News Sunday the 24th of April 2022 The news headlines: Two new GB2RS broadcasts Take part in SOS Radio Week VMARS nets The RSGB GB2RS News Service is delighted to announce two new broadcasts on Sundays. With a nod to how it all started back in 1955, we have introduced a transmission using amplitude modulation. This takes place in the 80m band on 3650kHz at 8 am UK time from the station of G4JBD in Bedfordshire. The intended coverage is the Midlands and the South East of England but it may be heard more widely when propagation is favourable. For those in the South West Glasgow area who are busy on Sunday mornings, we are now offering an evening broadcast on 2m. Delivered by 2M0GUI on 145.525MHz FM, the transmission is at 6.30 pm UK time. Every year thousands of people get into difficulty around our coast. Thousands of unpaid volunteers swing into action to save and rescue them. SOS Radio Week celebrates the work of these selfless volunteers. Amateur radio stations get on the air to raise awareness of the invaluable work of the Royal National Lifeboat Institution, National Coastwatch Institution and the many independent lifeboat and rescue organisations around our coasts. The activity starts at 0000UTC on the 1st of May and concludes at 2359UTC on the 31st. Participants are encouraged to become an official Registered Station and make as many contacts as possible, mentioning the reason for the event during their contact. For further details visit sosradioweek.org.uk The Vintage Military Amateur Radio Society will be displaying at the Blackpool Rally today. They have regular nets on 3.615MHz at 8.30 am on Saturdays using AM and at 8 pm on Wednesdays using USB to facilitate the use of ex-military equipment. On Fridays, the frequency remains as 3.615MHz at 7.30 pm using LSB. More at www.vmars.org. As part of the forthcoming Jubilee celebrations, the RSGB has announced further details of its GB70 special event station activities. The seven SES callsigns will be active across the Jubilee weekend, from the 2nd to the 5th of June, on multiple bands and modes by various clubs. After that weekend, these special callsigns will be available for activation by RSGB affiliated clubs or individual RSGB members until the 28th of June. Each callsign has a volunteer coordinator responsible for allocating operating slots in a published schedule. They will also collect the log files from those who have been activating the calls. For further information see the GB70 page in the RSGB Jubilee web section at rsgb.org/jubilee. Provisional results for the 2021 IARU Region 1 Marconi Memorial VHF Contest are available. A total of 762 logs from 27 different countries in Region 1 were received. You can read the provisional results at iaru-r1.org.

Next Sunday, the 1st of May, the UK Six Metre Group Summer marathon starts. It runs until the 2nd of August. Using all modes on the 50MHz bands, the exchange is your 4-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 22nd of April 2022. Last week was characterised by solar flares – lots of them! There were numerous strong flares, although the majority occurred in the early hours and so didn't affect the ionosphere over Europe. Solar flare events can cause short-lived radio blackouts as the energetic photons penetrate deep into the D-layer. Solar activity during the past 30 days has increased drastically with five of the top 10 strongest flares of Cycle 25 detected during this period alone. We have also had very strong sunspot activity with the solar flux index peaking at 160 on Thursday the 21st. The current crop of four sunspot groups probably means we can expect the SFI to stay high until at least early next week. NOAA predicts the SFI will stay above 130, but we may get even higher figures for a time. It also predicts a maximum Kp index of two next week, although that could easily rise if we get hit by matter from any incoming CMEs, which are getting more prevalent as the cycle continues. The good news is that, at the time of writing, it didn't look like we will get any coronal hole activity. There have been numerous reports of good conditions on the higher bands - 21, 24 and 28MHz – including openings to TX5N on the Austral Islands. Braco, 8Q7DX, who is on holiday in the Maldives, has also been worked. There have also been some signs of early Sporadic-E with very loud openings to Spain on 10 metres. So if the SFI stays this high and we don't get many geomagnetic disturbances it could be a good week for HF. And now the VHF and up propagation news. We have a classic spring start to things with low pressure over the near continent, aided by the increasing warmth of the spring sunshine, while colder regions to the north become home to high pressure near Iceland. Between the two, we will have a strong and cold-feeling east to northeasterly wind over the UK; not really the setup required for Tropo, since the strong winds and turbulence destroy any temperature inversion. The changes come along after this weekend as the low weakens and a ridge of high pressure extends south across the country with much lighter winds and a chance of Tropo, especially overnight. It is possible that isolated showers may offer a little rain scatter, but not a high probability. It would be better to consider possible aurora and meteor scatter as your exotic modes. In this closing part of April, the best is within reach, since Sporadic-E is a serious possibility on 10m and perhaps 6m. Use the beacons and clusters to guide you, but if you start to adjust to your summer operating rule of checking for Es mid-morning and late afternoon or early evening, then Es QSOs will soon come. The Winter minimum of meteor show activity is at an end with Sporadic meteor rates increasing towards their usual maximum in late summer. The Lyrids shower has passed the peak but continues to be active until the 30th. Moon declination starts the week negative with low peak moon elevations and short visibility windows but turns positive again on Thursday. Path losses are on the increase again as we are past perigee. 144 MHz sky noise is low all week except Saturday afternoon when the Sun and Moon are close in the sky for the five hours leading up to Moonset at approximately 1900hrs. And that's all from the propagation team this week.
A “skinny” meteor shower should be at its best tonight. The Lyrid shower turns up every year at this time, and has for at least 2700 years. But the number of meteors is pretty low — about 10 to 20 per hour. In part, that's because the object that supplies the Lyrids is a long way away. Lyrid meteors are bits of debris from Comet C/1861 G1 Thatcher. When the comet comes near the Sun, some of its ice vaporizes. That releases bits of rock and dirt into space. Over time, they spread out along the comet's orbit. Earth flies through that trail of comet dust every April. Some of the particles ram into the atmosphere and vaporize, forming meteors. A meteor shower is most intense around the time its parent body is closest to the Sun, when it releases fresh debris into space. For Comet Thatcher, that last happened in 1861 — the year it was discovered. Today, the comet is about 10 billion miles from the Sun and moving outward. It'll be farthest in a few decades. Then it'll turn around and head sunward, with its closest approach around the year 2276 — when skywatchers may see some great displays of Lyrid meteors. For now, check out the shower beginning in late evening, as the meteor stream begins to rotate into view. The window is short because the Moon will rise about 2 or 2:30. Its glare will overpower all but the brightest meteors — the offspring of a far-away comet. Script by Damond Benningfield Support McDonald Observatory
Morning sky watching continues to be wondrous. Evening isn't so bad either lately. Get ready for the April Lyrids meteor shower. And just why do comets have such long, strange names now?
It is time to be on the lookout for falling stars, or should I say meteors for the next few weeks. That is because the Lyrid Meteor Shower, annually runs from April 16-25. The peak viewing period will come on the evening of April 22 and early morning of April 23 with perhaps 20 or so meteors per hour. The moon is going to interfere with some of the more faint meteors during the peak viewing period, but if the sky is clear, it will be worth taking a look.
Episode 140 In this episode of the Observers Notebook podcast, host Tim Robertson talks to the Meteor Section Coordinator, Bob Lunsford about the upcoming Lyrids and eta Aquariids meteor showers peaking the evening of April 21-22, 2022 and May 4-5 2022.

GB2RS News Sunday the 17th of April 2022 The news headlines: RSGB AGM to be live-streamed Pop Up YOTA net today New EMF video The RSGB AGM is being live-streamed on Saturday at 12 noon. You can still submit a question for the RSGB Board to answer during the event, but you will need to do so before 9 am on Wednesday the 20th of April. Voting in the elections closes at 9 am on Thursday the 21st of April. The Society encourages all RSGB Members to use their vote. Full details of the event can be found on the RSGB website at rsgb.org/agm. A special Pop Up Youngsters On The Air net will be on the air today, Easter Sunday, at 1400UTC. This Pop-Up net is aimed exclusively at youngsters under the age of 25 and encourages them to call in and have a QSO with fellow youngsters on the air. The net controller for the first hour will be Declan, 2W0KYH who is aged 13. The 2nd hour is with Liam, M7LCB. The net is hosted by the FreeSTAR Amateur Radio network, which is a multi-node system where various digital radio modes are accessible including DMR, D-Star, Fusion C4FM and so on. For full connection details please visit freestar.network or email Oscar@freestar.network. The RSGB has just released a short video outlining the new EMF regulations and the help and tools the Society provides for radio amateurs. There is a wealth of information and guidance on the RSGB website and the Society hopes that this video will signpost that in a new way. The video is in the ‘Did you know?' playlist on the RSGB YouTube channel at youtube.com/theRSGB. The IARU Region Political Relations Committee, in conjunction with the Region's EMC Committee, has submitted a paper to a recent European Commission Call for Evidence with respect to Solar Energy Strategy. Solar energy systems, which include Solar PV, are a progressive technology whose use is to be encouraged. However, there are certain caveats to be noted in deployment and ongoing use. The IARU concerns are not with solar technology, but with the potential noise pollution from so-called optimisers. The paper that was submitted detailed elements of the ongoing research and monitoring by the EMC Committee in this area. The paper is available on the IARU Region 1 website at iaru-r1.org. As part of the Commonwealth Games activities, RSGB Special Event Stations will be activated from the four UK Home Nations and three Crown Dependencies. The callsigns will take the format of GB22G followed by the Regional Locator, for example, GB22GE, GB22GI or GB22GD. RSGB affiliated clubs and individual RSGB Members who are Full licensees will be able to book slots to activate a callsign themselves or to supervise operation by others. Further details will be coming soon. Radio Amateurs of Canada is supporting World Amateur Radio Day on the 18th of April by encouraging amateurs to get on the air and contact as many Canadian stations as possible. RAC official stations will operate across Canada from 0000Z to 2359UTC on the 18th. Look out for these special event stations with callsigns ending in RAC.

The SP DX RTTY contest runs from 1200UTC on the 23rd to 1200UTC on the 24th. Using the 3.5 to 28MHz bands where contests are permitted, the exchange is signal report and serial number with polish stations also sending their Region code. Running from 1900UTC on the 23rd to 2130UTC on the 24th, the First MGM contest uses the 50 and 144MHz bands. The exchange is your report and 4-character locator. Next Sunday, the 24th, the BARTG Sprint 75 Contest runs from 1700 to 2100UTC. Using 75 baud RTTY on the 3.5 to 28MHz bands where contests are permitted, the exchange is the serial number. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of April 2022. We had a week with declining solar flux index numbers, but with the ever-present threat of coronal mass ejections. The SFI declined from 101 on Sunday to 96 on Wednesday with the possibility of further falls as the week goes on. A solar filament located near the centre disk of the Sun erupted early Monday morning generating a faint, halo coronal mass ejection (CME) that appeared to be squarely Earth-directed. A moderate (G2) geomagnetic storm watch was added for the 14th and skywatchers at middle to high latitudes were also put on alert for aurora. Meanwhile, the quieter geomagnetic conditions earlier in the week saw 10 metres open up to some good DX. Laurie, G3UML reports a long path opening to Australia on 20m CW from 0730 to 0800UTC. He worked two VK2s and a VK3 and listened to VK5QD who was very loud. Next week NOAA predicts that the SFI may climb again, perhaps into the range of 100 to 110. Geomagnetic conditions are predicted to be generally quiet, but with the ever-present risk of CMEs pushing the Kp index up to perhaps four or five at times. A pair of coronal holes became Earth facing on Thursday as well, which may bring unsettled conditions again this weekend. If the Kp index stays low we can expect MUFs to be near seasonal norms, perhaps with openings up to 21 and even 28MHz at times. Look out for occasional early-season Sporadic-E openings as well, which could bring short-skip openings into Europe on 10 metres. And now the VHF and up propagation news The high pressure over the North Sea and Scandinavia will decline slowly allowing a new area of low pressure over the nearby Atlantic to drift east into southern Britain during the Easter weekend. This will mean that any Tropo benefits, particularly over the Irish Sea and the North Sea will decline during the weekend. The new low will bring areas of showery rain across the country with a chance of rain scatter propagation. This is likely to be a pattern for much of the following week with low pressure over southern areas and occasionally expanding bands of rain farther north. The solar activity has continued to provide aurora options, so again worthwhile checking the clusters and Kp index for early signs of auroral activity. It is also a given that random meteor scatter is always available, especially for those who like to be up early in the morning! The main mode to keep a watch out for during the coming week is Sporadic-E, which is just beginning to make an appearance on 10m and even higher bands using digital modes. Jet streams are important as potential sources of the atmospheric gravity waves that can contribute to Es. You should look to the jet stream 300hectopascal or hPa upper air charts to see where they are located. Try paths that cross them, especially where they cross mountain ranges like the Alps or Pyrenees. Note a hectopascal equals a millibar. The Propquest.co.uk website has a set of four 300hPa charts for the current day and from the beginning of May will also contain a daily blog highlighting that day's prospects. The Winter minimum of meteor show activity is coming to an end. This week the small daytime April Piscids shower starts on the 20th, and peaks two days later at 2200UTC. This also coincides with the peak of the larger, and currently active Lyrids shower also on the 22nd but earlier at 1300 UTC. With a ZHR of around 18, it should produce some good reflections. Moon perigee is on Tuesday so path losses are at their lowest. Moon declination is negative again and reaches minimum on Thursday so Moon windows will be short and peak Moon elevation low. 144MHz sky noise is high, peaking at over 3000K on Thursday so combined with the low elevations a poor week for especially VHF EME. And that's all from the propagation team this week.

The Australian Competition and Consumer Commission has joined forces with its UK and German equivalents in an agreement to prevent tech giants from using mergers and acquisitions to maintain market dominance. In a join statement, the three groups state that stronger control over mergers is required to create room for competition in the market, particularly in new areas of innovation.Microsoft has added new settings to Outlook that can enforce breaks between meetings in an effort to overcome the problem of wall-to-wall meetings and general digital overload. The setting can make meetings start five minutes after the usual hour or half hour, with Microsoft's own research suggesting even small breaks can have a positive impact when people are feeling overloaded. Now if only they could automatically mute everyone at the scheduled end time to stop overrun that would be good too.The EU is moving forward with its proposal to impose strict rules upon the use of artificial intelligence. Seen in draft form last week, the plan aims to outlaw the use of AI for general social scoring, the use of remote biometric detection in real-time policing, and more. The rules also demand compulsory transparency obligations whenever AI is used to interact with humans, to generate or manipulate content, like with deep fakes, or to perform social or emotional detection. If the rules go ahead they're expected to have widespread impact on AI technology initiatives across the world.In Britain, the country's former children's commissioner is taking legal action against TikTok over the collection of personal data about child users.

Starting tonight & peaking on Earth Day April 22 the Lyrids are making their appearance. These springtime meteors get their name from the constellation Lyra, which is shaped like a harp with a tail to the bright star Vega. From Greek mythology, this is the Lyre of Orpheus, the harmonious instrument that the virtuoso played at the gates of Hades in an ill-fated attempt to win back Eurydice from the Underworld. Orpheus the son of Apollo & the muse Calliope, being a demi-god, his singing & playing were so beautiful that animals & even trees & rocks moved about him in dance. Some folks speculate that this was a former incarnation of Marie Steiner von Shivers, who they also say was the famous Greek philosopher Hypatia of Alexandria – they both met their death by being was ripped to shreds. Perhaps, we can imagine the Lyrids as the 'Tears of Orpheus,' falling down from the heavens. I think it's interesting to contemplate these 2 powerful personalities, of Orpheus & Hypatia, who were both standing at a turning point of time when new impulse were coming in, which is what Meteor Showers are a sign. --- Send in a voice message: https://anchor.fm/hazel-archer-ginsberg/message
Comet Thatcher is pretty ordinary. It’s a ball of ice and rock that takes about 415 years to orbit the Sun. It follows a long, skinny orbit that takes it deep into the outer solar system — more than five billion miles from the Sun. The comet reminds us of its presence every year, though, with a meteor shower. And the shower should be at its best tomorrow night. It’s called the Lyrid shower because its meteors all appear to “rain” into the atmosphere from the constellation Lyra. Comet Thatcher was discovered 160 years ago this month. Amateur astronomer A.E. Thatcher was scanning the skies above his home in New York with a telescope when he saw a small, fuzzy blob. The comet soon became bright enough to see with the naked eye. A few years later, astronomers figured out that the comet was the source of the Lyrid meteors. As the comet moves close to the Sun, heat vaporizes some of the ice at its surface. That releases bits of rock and dirt into space. They spread out along the comet’s orbit. Earth passes through that path every April. So some of the bits of debris plunge into our atmosphere at speeds of 30 miles per second. At that rate, they quickly vaporize — forming the streaks of light known as meteors. This year’s Lyrids should be at their best late tomorrow night. Unfortunately, the gibbous Moon will be in the way during the peak hours. So only a few Lyrids are likely to shine through — the offspring of a comet. Script by Damond Benningfield Support McDonald Observatory

I'm your host Yucca. And today we are talking about astronomy, and space, science and the wow of all of it. So the reason that we chose today, Is this episode comes out on April 12th, which is Yuri's Night. Mark: Exactly. And that is the anniversary, and as it happens, it is the 60th anniversary of Yuri Gagarin's orbiting of the Earth, the first entry of humanity into space. And this was a remarkable achievement in many ways, not least of which was that he actually orbited. Later missions of the United States for example, tried to get capsules into orbit, but until John Glenn, they didn't succeed. So this was really a remarkable thing. And he had the first extra terrestrial view of space. Yucca: Yeah, and helped us gave us that view as well. And since then, there have been many, many humans who have gotten to see our planet from outside of it. Which is just amazing. And of course the space age has unfolded since then. And now we have the satellite images continuously watching our world and looking out far into the distant past. And it just amazing, amazingly beautiful and mysterious objects and giving us a completely different understanding of the context that we exist in. Mark: Yes. And to be fair, I think a different understanding of ourselves as exploratory creatures, we have invested, and it may not seem much relative to how much we invest in ways to kill one another. And other Yucca: weight loss pills. Mark: Yes. things that we invest, but we have invested a tremendous amount of money and effort, expertise, and knowledge and genius into flinging our machines into space so that we can learn extraordinary things. Extraordinary things. Yucca: And going back to the April 12th 61. we hadn't even flown past Mars yet. Mark: No. Yucca: That comes later. Now. Amazingly, we did that very, very quickly. But. We hadn't even glimpsed at are our neighbors that are sibling planets are telling us so much, or our studying of them is teaching us so much about ourselves, right? The studying Venus, studying Mars, that comparative planetology has really given us a leg up in understanding climate change and the history and the different possibilities of where our planet goes, depending on human management and all kinds of things. Mark: Yes. Yes. I am old enough to have lived through almost the entire space era. And I remember that when I was a kid, this misshapen smear was the highest resolution image we had of Mercury. For example, it was the very best we could do. And. That remained the best we could do until the Mariner missions. When suddenly we had these beautiful crystal clear Moon like shots of Mercury, it wasn't like we advanced in little steps. We went from essentially nothing, a completely undifferentiated smear to these beautiful high resolution images in a very short period of years. We've just learned so much. Yucca: And we did something very similar with Hubble, the Hubble space, telescope and excitingly, lots of fingers crossed, but the James Webb telescope, which is scheduled to launch on Halloween this year is one of those that we hope is this going to be another one of those, amazing transformations of the imagery and data that we can get back just to completely new level, Mark: An order of magnitude jump. Yucca: literally. Yes. Mark: A literal order of magnitude. And when you consider the extraordinary imagery that has come back to us from Hubble the miraculous the deep field images, the nebulae the galaxies. The extraordinary quality of these images in the way that they've helped to inform us about the nature of the universe, which is our world. Our world is in the universe. It's all operating according to the same rules. And it's just a really amazing time to be alive and to see the, see this information coming back. Yucca: Yeah. It's just it's. Wow. It's odd. Inspiring. it's, it's what we named this show after. That sense of wonder. Mark: Yes. Yes, because. We can talk a lot in our paganism about cosmology and people do talk about their cosmology a lot in the pagan world, whether it's that they believe in particular gods or an afterlife that is the happy hunting grounds or valhalla or some form of reincarnation or. Or whatever it might be. We in the naturalistic, non theist pagan world, we're looking at what we know for a fact is here and it is so amazing. It is so multifaceted and mysterious, not meaning mysterious as in woo. You can't understand it, but just, we don't understand some stuff yet. And it's, and we're finding more out all the time. Yucca: And as we find more out, then it just opens more and more questions and more mystery. And that's the mysterious part of it. Is it leads to more. Mark: But we also answer big questions. And that's another part that is just so gratifying that we have a standard model of cosmology, which as of this week is now in question because there may very well be a fifth force of nature. And I don't want to go down that rabbit hole because it's a hole. Yucca: Oh, this is another fun one though. So if you have time, if you've got the time, check it out. Yeah. Mark: Yes, definitely check it out. It's still a maybe, but the data are awfully good. And people are very excited about it and it may very well answered. Big questions about, for example, the reason that the expansion of the universe is accelerating, which is something that we have explained with this sort of magical term dark energy. But it may very well be that it is this. tiny force between at the microscope, at the subatomic level, which is driving the universe's expansion to accelerate. And I don't claim to be able to explain all of the steps that lead to that kind of conclusion, but people that are much smarter and more educated on this than I, I am, do believe that's the case. And. If that's the case, we have learned something fundamental and incredibly important about the nature of the universe. Yucca: Yeah, it's one of those textbook rewriting situations. So, and if that's not the case, it's even more interesting. Mark: Yes. That's not the answer then what is. Yucca: so it's often, much more exciting to be wrong than to be probably right. Cause again, we never know that we're actually right. We're really good at proving ourselves wrong, but we can never quite prove. Mark: Yeah, we can tell what's most likely to be right, but that's not the same thing as saying we're right. Declaration of my God exists, or this is the way the universe is a fundamentally unscientific way of approaching the world. It's a faith-based way of approaching the world rather than a science-based way of approaching the world. And. within the segment of the pagan community that Yucca and I live in, we are about the scientific understanding of the world. We believe that there is enough here to Revere and to celebrate and to be awed by and humbled by that we don't need the supernatural stuff. Maybe it's out there. Maybe it is. Maybe. Data is going to arrive one day that indicates that some of that stuff is true, maybe so, but I settle. I settled for the universe. Yucca: What a thing to settle for. Mark: Yeah. Yucca: This universe that we're talking about. We're part of. Mark: Of course. Yucca: And that's one of the really exciting things in the space sciences is that when we learn about that star or we launch a telescope, that's lets us look back 13 billion years. We're not just learning about something, oh, out there. Some imaginary thing. No, we're learning about us. What made us, what process made us what's happening to us? It's, we're looking at ourselves in a way, not the literal pattern and collection of atoms which is Yucca or Mark right now, but on a kind of conceptual level of what creates us and things like studying black holes, it seems so removed from our. From our reality and has it doesn't seem like it should have anything to do with us. And yet, as we studied black holes, we started to see, okay, so black holes can play a major role in distributing heavy elements throughout the galaxy, pushing them out into areas where you're more likely to be able to form life on planets that's away from the incredible amount of radiation and activity in the center of a galaxy where all that material is concentrated. So this is one of the many ways that we start going. Okay, well that is, we'd never have thought that argument, it might depend on the, on black holes until we start studying those things. Mark: And let's connect the dots there. What are we made of? We're made of a bunch of heavy elements. I mean, we're made mostly of hydrogen and oxygen, but we are made of also things like, as we were talking about zinc and copper and calcium and iron and those heavy elements formed in these catastrophic supernova events and then pushed out. By black holes, coalesced into a system which erected little pillars on two legs, things that are aware of themselves in the universe that can look out at the whole system and can have some level of comprehension of what it is and how works and that's You listener that's you and it's me. And it's all of us. It's so cool. Yucca: Yeah. It's just, and we see those connections all over the place picked black holes. Cause that's it an exciting topic, but. any other object, do you want to take a look at, let's talk about Nebby Lee or quasar. I mean, we just talked about quasars, but neutron stars and the Brown dwarves, all of these things, and we start to put this puzzle together. It's like those little drawings that, that kids have in their activity books, where they have the dots and you follow you draw from one to two to three to four, and then all of a sudden it makes us incredible picture to connect the.pictures. And that's what we're doing. And. Mark: and let's remember for a minute why it is that we're studying situations like black holes because the edge cases, the extreme cases are what is left in what we don't understand about the universe. We have physics that completely explains everything that a human experiences on Earth. There, there aren't. Yucca: In terms of the scale that we're experiencing Mark: Yes. In terms of the scale that we're Yucca: the ball dropping the, that kind of thing. Yeah. We've got that. We've had that since Newton, right? That's. Mark: We've had that for a long time. So where we go is to the edge cases, the extreme cases, cases of extreme gravity, extreme radiation, extreme electromagnetism. Those are the places where we start to see the rules that apply at our scale breakdown. And that tells us much more about the nature of the universe. Yucca: And allows us to do more with it. to start to put together understandings that okay. That extreme case, but we ex we start to understand it in the exception, in that extreme case. And then we can bring it back and we can start to apply it to. Okay. Well, what's happening with Mercury's orbit. We're seeing some time dilation there. Okay. But then we can apply it and start using it in things like GPS, where it wouldn't work with, if we didn't have that understanding GPS wouldn't work. So yeah. Mark: So this is not just a mental exercise. It is a really fun mental exercise and you can get lots of wow out of it. And obviously Yucca and I do and hope that you do too, because it's just an extraordinary voyage to take to undertake, trying to understand even a corner of what this whole universe is about. it's so inspiring and it can bring tremendous joy. but more than that by reaching out to explore in those really extreme cases, we start seeing, Oh, well that actually implements it our scale a little bit, not very much, but a little bit. And we start realizing how interconnected it all is, how much it's all of the same fabric really. Yucca: Yeah, something to add to this is what we're talking about is so huge that no one person could possibly know it all. So don't worry about knowing it all. There's always going to be somebody who knows more about something, so that doesn't need to get in the way of pursuing something that you're interested in. If you're interested in learning about the Moon or supernovae or things like that. Sure. They're experts and why, and maybe you won't be the world's leading expert on it, or maybe you will. That'd be awesome if you were, but. But you can still learn about the piece here and a piece there and, or you can simply just enjoy being out and noticing, Oh, that red star there. Oh, that's Betelgeuse . All right. I heard that's near the end of its lifetime that maybe we might get to witness it go supernova one day. You don't need to know everything. So don't let the what's that old expression. don't let perfection Mark: Don't let the perfect be the enemy of the good. Yucca: Yes. So. Mark: I would go even a little step further, which is that there are people who are not particularly scientifically minded at all. They're much more aesthetically oriented, more artistically oriented, just the Hubble images, just. Just admiring the magnificence of what's out there in the universe manifest simply through the laws of physics is enough. You if you have a predisposition to want to understand what you're seeing, when you look at those images, then great. Learn about what you're seeing. If you don't have that predisposition, just. Enjoy the show, the universe, the greatest show on Earth, except it's not just on Earth. It's the greatest show in the universe. Yucca: Exactly and all the stuff that NASA does, all the images that it puts out, those are all public domain. And today, some of the real old stuff from some of the older missions, it's hard to get ahold of, but anything that's being produced today, the Perseverance images coming back, those are being uploaded online and you have access to those. I mean, it's just a few swipe of your thumb to get access to those. Mark: I used NASA image from the international space station of the Sun peeking over the limb of the Earth for the cover of my book. Atheopagan ism. Because I knew that it was public domain. It's owned by all of us because we all paid to make it happen. All of us in the United States helped to pay, to make it possible to shoot that photograph. And so that's what I used. Yucca: And the logo actually for the podcast is a Is multiple images put together. So it's not just one image, but it's based on many images, which are images from various different space missions. Mark: Not that we like space or anything. Yucca: I yeah no, no interest in space. no, that's actually my masters. That's what my master's is in. Yeah. But and I'd like to teach it and talk about it with kids and adults, and pretty much anyone who will listen. talk about space with you. This is Mark: That's the great thing about a podcast is that basically if they download it and decide to listen to it, then they've already agreed and you can just talk. Yucca: So, so we've been talking about kind of these big things. before we jump into some of the things that, that we can do in our everyday or every night practices I just wanted to mention that 2020 was a really hard year on so many different fronts, but some of the silver lining from that was the many of the incredible explorations and advances we made in the space sciences and 2021 already. I mean, we're just coming out of the first quarter. So there's so much that we are learning. Continuously and the accessibility of it is really amazing too. There are some amazing YouTube channels where you can just tune in to very high production quality presentations on what's what's going on. What's the newest news. What's you know, what did Parker probe come up with and this stuff that we're talking about the challenges to the standard model we talked about Spacetime is one of my favorite ones like PBS. I don't remember the, his name, but he's got a, he's an astrophysicist with a lovely Australian accent. Great to listen to is so there's a bunch of those and we just are in this. This is just such a great year. I mean, we've talked a lot about Perseverance and Ingenuity and James Webb and there's just last year, new, more material coming from New Horizons, which is my personal favorite mission out there. the one who went by Pluto but is doing. Now doing astronomy. So we've done some stellar parallax with it that from a distance that we had never been able to do before. So it's just one of those, one of those places that I think is helpful to have some gratitude and excitement about that, even though it was a hard year, we had some just amazing Discoveries and advances. Yeah. Mark: Yes. And there was renewed interest in instrumentation that was very old, the Voyager missions, which had been on well, we're going to keep listening to the occasional beep, but that's about it. they'd been ignored now having left the Helio sheath Their discoveries are much more interesting again. And so there's a lot more attention being paid to the signal that is being directed by these objects that are the farthest flung human objects ever. They have left the Solar System. They are beyond way beyond Pluto's orbit at this point. Yucca: Oh far. Yes. yeah, I don't, we could look up how many AUs out they are. Yeah. I mean, there's still within the Sun's Hill Sphere, but they're in the interstellar medium. Now. They're no longer being. Strongly affected by the solar wind and the Sun's magnetic influence. So just like the Earth has a magnetic field, the sun does, and that's what the Voyagers are leaving. Mark: Yes. Yucca: isn't it just delightful that these things were launched in the seventies Mark: I remember when they were. Yucca: And I'm also the only visits to the ice giants. Mark: Yes. Yucca: Voyager 2 past in 89 and we haven't been back since. Mark: Yes. and the, so the pictures of Uranus and Neptune are as good as they get. For us right now. And they basically look like big fuzzy balls with with little storms and some rings. But we learned tremendous amounts. Yes. Yucca: Yeah. A lot of mysteries today. Mark: yeah, I mean, they were little points of light before we went out to look at them and By gum was right. There's a planet there. Yucca: With other planets going around them because Triton is quite a story. That's an interesting one. Mark: It certainly is. It certainly is. well, and that gets us into the Moons of the Solar System, which is a whole tangent that we could go incredible places. All the deep ocean Yucca: The, IWOWs Internal water ocean worlds, and cryo vulcanism and. We haven't even looked beneath these surfaces to see if somebody is there Mark: right. Yucca: From an astrobiological perspective these worlds are probably far more habitable than earth is earth is quite hostile, but I wound with these nice many kilometers thick of ice that protect them from the solar radiation and impacts, and they have internal sources of heat and liquid wood water, all the things that we need for life, but in a much more steady stable environment. Yeah. And that's, we'll have, hopefully we'll have the Europa clipper happening in the next decade and maybe we'll get a look, even though we're still not landing. We're. not Mark: We're looking. Yucca: We're just looking. Yeah, we're looking, but we're getting to look with a lot more detail than we ever did before. Mark: By the way, if you haven't seen it, and I'm not going to say any more about it because there should be no spoilers. There is an unbelievably good, incredibly low budget science fiction film called Europa Report. And. You've just got to see it. I mean, one of the things that's great about Europa report is that it's one of the few space exploration movies I've ever seen, where the characters are actually scientists. They're there for the data. They really, they care about the data. that's the most important thing to them. I don't know if you've seen that or not. Yucca: I have not watched it in full, I have watched parts of it. but yeah I'm familiar with it. Yeah. So we've talked about the sense of awe that the scientific perspective, which includes. The not just willingness, but the excitement in having our understanding be challenged by a new data. But there's also the personal relationship with the night sky that as we're moving into warmer weather, for those of us in the Northern hemisphere, It can be a really great experience and enriching to spend some time with the night sky. Mark: Especially if there's some whizzbang event happening like a lunar eclipse or a meteor shower. and they're not that uncommon, cool stuff happens in the sky all the time. Some of the cool things like comments, less frequently, at least comments that are visible to the naked eye, but a, a lunar eclipse or or a meteor shower is nothing to sneeze at. It's very cool to be out under the stars and see these amazing things. Yucca: And even when there's not a shower, there are still, if you're in a dark area, you probably going to see multiple meteors and a single night. yeah. So there's actually a, one of the major meteor showers coming up just in the next week or so the Lyrids is so, and the, it will not it's we're moving towards the full moon. But we won't be all the way at the full moon. So when you have the full moon, it makes it harder to see because there's more light, but that's a great one. There's I think 10, 15 per hour is estimate Mark: I think, so that sounds about right. Yucca: It's one that actually is easier to see in the late evenings, which is a little bit unusual. Most of the time, the best viewing for the meteor showers is right before Dawn is between midnight and Dawn. But this one, your local time, nine to 10, just look Northeast and look for Vega actually. And that should be a good clue for where to look so. Mark: So go ahead and do it for real. it's great. too, like I have the Hubble ultra deep field image on my focus and an Apollo 17 portrait of the Earth on my focus. the space has a real presence in my kind of altered. Personal spiritual practice, but there's nothing like the real thing. And especially if you can get to a very dark area, like a desert or out on an Island in the ocean or something like that there's just nothing like it. Yucca: And even if you're in a city, I mean, the moon is amazing. And yeah it's not only out at night. If you can't get out to see it at night, go ahead and take a look at it during the day. You can still make out lots of the craters and studying the line between night and day on the moon. So the Terminator there where you see the dark and the light, you can see all kinds of amazing details. And it's just stunning. Mark: we should also mention the astronomy picture of the day, which is a wonderful web resource that is managed by NASA. It's just a pod.nasa.gov. And a pod, meaning astronomy picture of the day and beautiful images of space with explanations of what we're seeing and what is significant about them. and as we said before, they're all public domain. it's, feel free to download them, use them for your wallpaper on your computer or whatever else you want to do with them. Yucca: And if any of you are listening on the 12th and it's Yuri's Night there are a lot of, there's a lot of space parties tonight, and lots of them are online. As well that you can just tune into, if you want to be a part of that kind of excitement and sort of celebration. Mark: It's probably a little early because of the pandemic, but typically there are live Yuri's Night parties at Air and Space museums or natural history museums. in many cities, they're all around the world and those, I've attended one of them. but it was such fun. It was everything from lectures and planetarium shows and that kind of thing to dancing. It was. It was great. It was just a really good time. Yucca: With a healthy dose of star Trek fandom, and all of the kind of related adjacent sci fi stuff. Okay. Mark: Yes. Yucca: Well, Mark, thank you. This has been a joy and if we kept at it, we could talk about space for many more hours, but I think we should let folks go. Mark: Okay, that sounds good. All right. A pleasure. Yucca. Have a great week.
The 365 Days of Astronomy, the daily podcast of the International Year of Astronomy 2009
Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night. April of 2021 delivers a few mornings and a few evenings of lunar close encounters, as well as a meteor shower, as we stay up later to get those dark skies. April 22nd – LYRID METEOR SHOWER – 2021 is a decent year for the Lyrids, if you’re willing to get up in the morning to watch. At only 10-20 meteors per hour, it is a minor shower, and we have a Moon just past its 1st quarter, so it won’t get drowned out by moonlight…after 4am. You’ll still be able to see SOME meteors at night, but it’ll be better without the Moon’s light pollution. So look North in general in the morning before dawn. The shower is greatest on the 22nd, but you might see some on the 21st and 23rd as well. Just remember each meteor is piece of debris left over from a comet, and we’re crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. Some advice for watching: - Find a dark location and lie down in a reclining chair or something that insulates you from the ground. - Check the weather to see if the skies will be clear. - Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something. - If you’re feeling extra nerdy, do a scientific meteor count (S&T and IMO).

Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night. Naked-eye PLANETS... Sunset – Mars Mars (SW-->W) – Look SW and two-thirds of the way up the sky after sunset to find the non-twinkling reddish-orange dot, much brighter than everything around it, above Taurus in the beginning of the month and above Orion toward the end. Sets around midnight in the WNW. Throughout the night – None at the moment Morning – Saturn, Jupiter Saturn, Jupiter – The two gas giants are low in the SE, getting higher and rising earlier each day. Look SE in the morning (after 5am in the beginning of the month, after 3am by the end). Jupiter will be on the left, with Saturn up and to the right about 15˚. EVENTS... Waning Gibbous (Mostly lit, rises later at night) Last Quarter Moon – 4th (Visible from midnight into the morning) Morning Crescents (look East in the AM) New Moon – 11th (darkest skies) Evening Crescents (look West after Sunset) First Quarter Moon – 20th (Visible until midnight) Evening Gibbous (Mostly lit, after Sunset) Full Moon – 26th (Visible all night) 5th – 7th – Close Encounter – Moon, Saturn, Jupiter – Before sunrise in the SE, between 5am and 6am EDT on these mornings, a beautiful crescent Moon will be passing by our two biggest gas planets. On the 5th, the Moon will be about 13˚ to the right of Saturn. On the next morning (the 6th) the Moon will be just 4˚ under Saturn. Then on the 7th, our crescent Moon hangs out just 5˚ below Jupiter. 15th – 17th – Close Encounter – Moon, Mars, Pleiades, Taurus – Get out there between sunset and midnight to find the crescent Moon in the West right next to Taurus, with the Pleiades on the opposite side, and Mars far above. On the 16th the Moon moves closer to Mars, leaving Taurus and the Pleiades behind. Finally, on the 17th, the Moon is just 5˚above Mars. 22nd – LYRID METEOR SHOWER – 2021 is a decent year for the Lyrids, if you’re willing to get up in the morning to watch. At only 10-20 meteors per hour, it is a minor shower, and we have a Moon just past its 1st quarter, so it won’t get drowned out by moonlight…after 4am. You’ll still be able to see SOME meteors at night, but it’ll be better without the Moon’s light pollution. So look North in general in the morning before dawn.

Just remember each meteor is piece of debris left over from a comet, and we’re crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. Some advice for watching: Find a dark location and lie down in a reclining chair or something that insulates you from the ground. Check the weather to see if the skies will be clear Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something. If you’re feeling extra nerdy, do a scientific meteor count (S&T and IMO) CONSTELLATIONS... Use a sky map from www.skymaps.com to help you out. After Dinner: Leo, Orion & his winter companions – Leo will be high in the South, almost straight above you. It has a backward question mark with a right triangle to the left of the question mark. Also, take a moment to get your last glimpse Orion, Taurus, the Pleiades, Gemini, Auriga, and Canis Major off in the West. Before Bed: Big Dipper, Bootes – If you look above Leo, behind you and high in the sky, you should find the Big Dipper: seven very bright stars that form a spoon shape. Now if you take the handle of the Dipper, follow its curve to the next bright star you see, about 30˚ away, which is Arcturus. “Follow the arc to Arcturus.” That’s the brightest star in Bootes, which looks like a kite. Take that same curve, and follow it about another 20˚ to “speed on to Spica”, the brightest star in Virgo, one of my favorite constellations, since it reminds me of the Dickinson Mermaid. Before Work: Lyra, Hercules, Hercules Cluster – Look pretty much straight above you, and find the brightest star up there. You’ll notice a parallelogram attached to it. This is the brightest star Vega, part of the constellation Lyra, the harp. Next to that is a keystone shaped constellation called Hercules. On the right side of the keystone is a small cluster of stars known at the Hercules Cluster, which is a collection of hundreds of stars on the outskirts of our galaxy. Given how high it is in the sky right now, you might catch its faint fuzziness with your naked eye, but a set of binoculars or a small telescope will really help you see it.
GB2RS NEWS Sunday the 28th of March 2021 The news headlines: Ham Radio Friedrichshafen cancelled In-person exams to resume 18th April is World Amateur Radio Day The in-person Ham Radio international amateur radio exhibition held in Friedrichshafen, Germany, has once again been cancelled. With the Covid-19 pandemic maintaining a firm grip on world events, the venue has been forced to postpone the event until 2022. The dates for 2022 will be the 24th to 26th of June. Details of any online activities in place of this year’s event will be released nearer the time. The RSGB remote invigilation exams have been a great success during the Covid-19 pandemic. The Society can now plan to resume exams for candidates who prefer to sit them in a club setting with in-person invigilation. The RSGB will start accepting bookings from club Examination Secretaries from the date when the Government lifts all Covid-19 restrictions in their part of the UK. The Society will release further details shortly. The online remote invigilation exams will continue in parallel. Mandatory practical assessments at Foundation level will remain suspended pending an ESC/ESRG-led review and consultation on their long-term future. The 18th of April will be World Amateur Radio Day. It was on this day in 1925 that the International Amateur Radio Union was formed in Paris. The theme for 2021 will be ‘Home but never alone’. Due to Covid-19, many gatherings and amateur radio events have been cancelled, however, amateur radio kept us connected. Listen out for special event stations around the world that will be on the air that day. The RSGB is holding its AGM online this year on Saturday the 24th of April and will live-stream the event. You can submit written questions for Board Directors in advance through a form on the Society’s website at rsgb.services/gb2rs/007. After the formal business part of the meeting, EMC Chair John Rogers, M0JAV will give an update on Ofcom’s new EMF regulations. In the UK, the clocks went forward one hour at 1 am today, the 28th of March. This means we are on British Summer Time. Please note that many contests and other events often state the timings in UTC or GMT, which will be one hour behind the local clock time here in the UK. The next edition of RadCom Basics is now available. It includes articles on Using a Multimeter – both digital and analogue, tracking down sources of interference and part two of Making Small Metal Boxes. RSGB Members can read previous editions of RadCom Basics by going to rsgb.org/radcom-basics. You can also register to receive notification of subsequent issues as they become available at the same address. At the request of the European Commission, the IARU met with representatives of the automotive industry, standards bodies and the Commission on the 25th of March. It was to review the current position on the development of an emission standard for Wireless Power Transfer for Electric Vehicles. There was a frank exchange of views and the Commission determined that further joint tests should be arranged. The IARU confirmed it was content to participate and welcomed the initiative. A further meeting will take place once the relevant tests have been completed, with a view to making progress towards an emission standard. Read the full news item at iaru-r1.org. There is an IET webinar about Amateur Radio on the 12th of May starting at 7.30 pm. Phil Gould will give you an appreciation of amateur radio, a hobby that puts science and technology into action. You can register on the IET website at theiet.org, then go to the events tab. Registration is open to non-members as well as members of the IET. Lee, M0RLE started a net at the beginning of the first lockdown. It is every Monday evening on GB3RF and GB3PF and usually attracts over 20 people. He has been working most of the lockdown but has kept the net going including contacting people if they miss the net to check that all is well. Well done Lee. The short film ISS_Overs won the Best Dramatic Short at the Quarantini Monthly Film Festival. It has also been selected as a finalist in the Awards Sections of the WeMakeFilms International Film Festival. It is about an elderly amateur radio operator who catches a signal from the International Space Station while in lockdown. Now the DX news Lee, HL1IWD will be active holiday style as HL1IWD/5 from Koje Island, IOTA reference AS-081, between the 2nd and 4th of April. He will operate CW and some FT8 on the 40 to 20m bands. QSL via the bureau, or direct to EA5GL. Keith, KL2JE will remain operating from Dutch Harbor, Unalaska Island, NA-059, until the 10th of April. In his spare time, he is on 20 metres using FT8. Mats, SM6LRR, will be active as 8Q7MS from the Maldives between the 28th of March and the 10th of April. He is operating holiday-style on mainly the 40 to 15m bands using CW, but he will also use SSB. Now the Special Event news For the annual RAFARS Airfields on the Air activity, GB0WYT – standing for RAF Wyton, Cambridgeshire – will be operational on the 3rd and 4th of April. This is the ninth year of operation. Due to the current restrictions, the callsign will be operated by RAFAC Radio Staff and members of Huntingdonshire ARS who live locally to RAF Wyton. Subject to conditions, they will be operating on the HF bands using CW, voice and RTTY, PSK31, FT8; they will also be on 2m FM and SSB. John, MW1CFN will be active as GB1004FTS from Anglesey, EU-005, between the 25th of March and the 8th of April. He will operate SSB and digital modes on the HF bands, 6 and 2m. QSL via Logbook of The World or direct. The special callsign celebrates the 100th anniversary of the Royal Air Force’s No 4 Flying Training School, which opened on the 1st of April 1921. Now the contest news The RSGB VHF Contest Committee will once again accept portable entries from stations within some areas of the UK from the 29th of March. Different parts of the UK have different regulations, so please ensure you obey your national and local government’s advice. Details are in the RSGB Contest Committee Newsletter and you can subscribe at rsgbcc.org. The CQ World Wide WPX SSB contest ends its 48 hours run at 2359UTC today, the 28th. Please check the rules as there is a new multi-station category. Using the 1.8 to 28MHz contest bands, the exchange is signal report and serial number. On Wednesday the UK EI Contest Club 80m contest runs from 2000 to 2100UTC. Using CW only, the exchange is your 6-character locator. Next weekend the SP DX contest runs from 1500UTC on the 3rd to 1500UTC on the 4th. Using CW and SSB on the 1.8 to 28MHz contest bands, the exchange is signal report and serial number. SP stations will also exchange their Province code. On Sunday the 4th of April the First 70MHz contest runs from 0900 to 1200UTC. Using all modes, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 26th of March. What a mixed week we had, with large geomagnetic storms interspersed with quiet periods. The first storm occurred last weekend when the Kp index hit six on Saturday and then five on Sunday. This wasn’t unexpected and we did warn that it might happen in the last GB2RS broadcast. A second storm occurred when a weak shock passage was detected at around 1920UTC on Wednesday evening. This was likely related to a coronal mass ejection coming off the Sun’s eastern limb, which was observed on the 20th of March. The solar wind increased from 375km/s to around 440km/s and the Bz Interplanetary Magnetic Field component tipped south. Otherwise, it was relatively quiet on the sunspot front with the solar flux index climbing from 77 on Sunday to 84 on Thursday, reflecting the increased UV due to groups 2811 and 2812. Conditions have been a little lacklustre, with daytime maximum usable frequencies over a 3,000km path struggling to climb over 18MHz at times. Next week NOAA has the solar flux index prediction at 78 all week. It also predicts unsettled geomagnetic conditions on Sunday, Monday, and Tuesday, with the Kp index set to rise to five thanks to a high-speed stream from a coronal hole. Expect depressed critical frequencies and MUFs until this clears later in the week and the Kp index returns to more normal values. This might be a good time to check your antennas so that you are ready for the 10 metre Sporadic-E season in a few weeks! And now the VHF and up propagation news. After some welcome Tropo down to Atlantic France and Northern Spain early last week, we are in the midst of a very disturbed period of weather and this will continue into early next week. Perhaps contrary to expectations there could be some more Tropo on the southern warm air side of a waving front over southern Britain. These will most likely be west-east paths from southern Britain into northern Europe. Otherwise, we can hope the frontal rain band may provide limited rain scatter options on the GHz bands. From about Tuesday, a new high will establish a dominant position over the UK and this could make Tropo more likely again, but this will be a cold air high and usually, these are not the best providers of good Tropo. As we enter April in the coming week, it's worth dusting down the Sporadic-E equipment and consider looking at 10m or 6m digital modes for early signs of life. If the locational trigger is jet streams, in this case, it would favour Scandinavia and the Baltic region. For EME enthusiasts, declination goes negative today, so peak Moon elevation will fall as the week progresses and Moon windows will shorten. Path losses are at their lowest with perigee coming up on Tuesday. The Lyrids meteor shower will start to ramp up in about two weeks’ time, peaking on the 22nd of April, but until then, the best time for meteor scatter contacts is the pre-dawn random meteor enhancement. And that’s all from the propagation team this week.
GB2RS NEWS Sunday the 21st of March 2021 The news headlines: Get ready for Summer time RSGB Youth Award Blue Ham this weekend In the UK, the clocks go forward one hour at 1 am next Sunday, the 28th of March. This means we will be on British Summer Time. Please note that many contests and other events often state the timings in UTC or GMT, which will be one hour behind the local clock time here in the UK. The RSGB Youth team has created a new award, aimed at younger people but it is also open for anyone to try. Called the Radio Surfer Award, it encourages experimentation with all types of radio communications. There is a list of possible activities, each with a points value. All you have to do is get the same number of points as your age. You don’t have to be licensed to take part although having a licence will give you more options. For more information about this and the RSGB Youth Award, see rsgb.org/youth-award. The Royal Air Force Air Cadets Exercise Blue Ham 21-1 is on the MoD 5MHz shared band this weekend. RAFAC and other MoD Cadet formations will be on air over the period of operation using SSB and data modes. The Exercise Blue Ham website is at alphacharlie.org.uk. Voting for the RSGB elections is now open. The Calling Notice, Resolutions, candidate statements and voting process are on the Society’s website at www.rsgb.org/agm. Voting ends at 9 am on Thursday the 22nd of April. The RSGB will be holding its AGM online this year, on Saturday the 24th of April, and will live-stream the event. RSGB Members will be able to submit written questions for Board Directors in advance through a form on the AGM web pages. The election details are also in the April RadCom, which RSGB Members will have started to receive in the last few days. The RSGB has published an update to the RSGB EMF calculator on the website at www.rsgb.org.uk/emf. This version has had the front sheet changed in response to comments and suggestions from people who have tried using it. We are grateful for all the helpful suggestions received. Further work is needed to update the frequency dependant antenna data and would appreciate volunteers to help with this exercise. It has also been updated to use the Ofcom calculator v0.1.2 published on their website. This does produce separations for frequencies less than 10MHz. We continue to work on the calculator including producing a version that works with the newer ICNIRP2020 limits. Amateur Radio on the International Space Station is once again operational, following a spacewalk on the 13th that worked on the Columbus module cabling. The Columbus amateur station, which typically uses the callsign NA1SS, is the primary ARISS amateur radio station used for school contacts and other activities. Trowbridge & District ARC and Leyland & District Amateur Radio have shared their stories of running nets during the pandemic to support their members. You can read about them on the RSGB’s ‘Get on the air to care’ clubs and groups web page, rsgb.services/gb2rs/006 Now the DX news Mats, RM2D will be active holiday style as 8Q7MS from the Maldives, IOTA reference AS-013, from the 28th of March to the 10th of April. He will operate CW with some SSB, mainly on the 40 to 15m bands. QSL via Logbook of The World, or EA5GL. Barring Covid-related restrictions, Janusz, SP9FIH will be active as TO1K from Saint Martin, NA-105, between the 22nd of March and the 5th of April. QSL via Club Log’s OQRS, or via his home call. Now the Special Event news John, MW1CFN will be active as GB1004FTS from Anglesey, EU-005, between the 25th of March and the 8th of April. He will operate SSB and digital modes on the HF bands, 6 and 2m. QSL via Logbook of The World or direct. The special callsign celebrates the 100th anniversary of the Royal Air Force’s No 4 Flying Training School, which opened on the 1st of April 1921. GB2VAX will be operational from the QTH of Andy, G4ISN of Welland Valley ARS, until the 28th. Now the contest news Please remember to check before the contest for any new rules due to lockdown and social distancing, which may differ around the world. The RSGB strongly advises obeying your national and local government’s advice. The Russian DX Contest ends its 24-hour run at 1200UTC today, the 21st. Using CW and SSB on the 1.8 to 28MHz contest bands, the exchange is signal report and serial number. Russian stations will also exchange their Oblast code. On Tuesday, the SHF UK Activity Contest runs from 1930 to 2230UTC. Using the 2.3 to 10GHz bands, the exchange is signal report, serial number and locator. Also on Tuesday the IRTS 80m Evening Counties Contest runs from 2000 to 2100UTC. Using SSB only, the exchange is signal report, serial number and county code. On Thursday it’s the 80m Club Championships from 2000 to 2130UTC. Using SSB only, the exchange is a signal report and serial number. Next weekend it’s the CW World Wide WPX SSB contest. It runs for 48 hours from 0000UTC on the 27th to 2359UTC on the 28th. Please check the rules as there is a new multi-station category. Using the 1.8 to 28MHz contest bands, the exchange is a signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 19th of March. We had a week of settled geomagnetic conditions, following a mixed weekend. The consensus on the Commonwealth Contest was that conditions were not too good, although plenty of amateurs managed to put VK in their logs, despite the Kp index hitting four during the event. The Sun remained fairly quiet, with a solar flux index of 81 on Saturday and 78 on Sunday. Otherwise, the DX interest has been focused on the Russian DXpedition A25RU to Botswana. They are there until the 26th of March and will be operating all modes, including CW, SSB and FT8. March is a good month for these North-South paths and Predtest.uk predictions show that 1600-1800UTC is probably the best time for a contact with Botswana on 30 to 17 metres. Next week NOAA predicts the solar flux index will remain in the mid-80s, although this weekend is likely to see unsettled geomagnetic conditions again thanks to a high-speed solar wind emanating from an Earth-facing coronal hole. Expect maximum usable frequencies to decline, after the potential for pre-auroral enhancement as the plasma hits. We expect to see the Kp index rise to four on Saturday and Sunday, although this will improve as the week goes on, bringing a more settled ionosphere and a predicted Kp index of two. Meanwhile, ionospheric conditions remain subdued due to a lack of real sunspots. Spring remains a good time for North-South paths, and we also have the Sporadic-E season to look forward to in a couple of months. And now the VHF and up propagation news. The coming week is again suggesting that high pressure will feature on the weather charts for much of the period, at least in the south and east. This gives a possibility of further Tropo opportunities for most parts of the country, at least at first. The trend thereafter is for Atlantic fronts to reach the west and north of Britain by mid-week, bringing unsettled weather conditions and putting an end to any Tropo there. But to compensate a little, it could introduce some rain scatter for the GHz bands. There are always hopes that some out-of-season Sporadic-E could crop up, and there were weak 50MHz openings for digimodes last week, but ideally, we need to be a bit further on into April before getting too excited. Moon declination is at maximum on Monday, so peak Moon elevation gets to 62 degrees in the UK and the Moon is above the horizon for more than 16 hours. As we passed apogee in the middle of last week, path losses will continue to fall as the week progresses. Meteor scatter enthusiasts will have to be content with the pre-dawn random meteor enhancement until the Lyrids meteor shower, which is still a month away. And that’s all from the propagation team this week.
GB2RS NEWS Sunday the 14th of March 2021 The news headlines: New Ofcom EMF guidance Direct to Full – respond NOW Blue Ham next weekend Ofcom has just published specific advice to amateurs about the new EMF Licence condition. It is based around an FAQ type of document. It attempts to address common questions that Ofcom and the RSGB have been asked since the original announcement on the 1st of March. It contains some worked examples to help to understand. Go to ofcom.org.uk/emf. The RSGB will continue to publish advice through the EMF pages at rsgb.org/emf. You have just a few hours left to share your views in the RSGB’s Direct Entry to Full licence consultation. The background, draft syllabus and the link to the survey are on the Society’s website at rsgb.org/direct-to-full. The survey closes at midnight tonight, the 14th. The Royal Air Force Air Cadets will conduct Exercise Blue Ham 21-1 on the MoD 5MHz shared band over the weekend of the 20th and 21st of March. RAFAC and other MoD Cadet formations will be on air over the period of operation using SSB and data modes. The Exercise Blue Ham website can be found at alphacharlie.org.uk. CQ magazine has introduced a contest category to enable a multi-operator team entry during the Covid-19 pandemic. This new category will be permanent, not just for the duration of the pandemic. Basically, the Multi-Distributed category allows up to six single operators, each in a different location within the same country, to form a team. Each station uses the same callsign but must operate on different bands. Scores are added together. Ofcom has confirmed that operating a club station in different locations using the same callsign simultaneously by club members is permissible. Only club members who hold a Full Licence in their own right may operate the club stations. Please read the rules at CQWPX.com. The next such contest is the CQ World Wide SSB contest on the 27th and 28th of March. Although 2020 brought devastation across the world, the RSGB rose to the challenge of supporting radio amateurs both in the UK and around the world. It also provided new ways for people to get started in, or come back to, amateur radio. The March RadCom included an article that looked back at this great amateur radio success story. You can read the feature and see the striking infographic on the RSGB website at https://rsgb.org/main/blog/news/rsgb-notices/2021/03/07/2020-a-year-in-numbers/ As part of the RSGB’s continuing Get on the air to care campaign with the NHS, and to link with British Science Week, the Society has launched a series of videos. Whether you’re a new Foundation, Intermediate or Full licence holder, the six videos will introduce you to some useful practical skills to help you make the most of your licence. Take a look at rsgb.org/practical-skills. Amateur radio operators are invited to take part in a free emergency communications training weekend. Taking place on the 10th and 11th of April, this virtual event will involve video presentations, including Q&A sessions, by communications and emergency response experts. To find out more, go to commacademy.org. The RSGB is delighted that more than 3,000 people have now passed their Foundation licence via the remote invigilation exam process. Congratulations to them – and welcome to everyone who has become a radio amateur over the last year. The RSGB provides a range of resources to support new licensees, so take a look at rsgb.org/beyond-exams.

Now the contest news Please remember to check before the contest for any new rules due to lockdown and social distancing, which may differ around the world. The RSGB strongly advises obeying your national and local government’s advice. This weekend the longest-running RSGB contest takes place. The Commonwealth Contest runs for 24 hours until 1000UTC today, the 14th. It’s CW only and runs on the 3.5 to 28MHz contest bands. The exchange is signal report and serial number. HQ stations around the world will also send the letters HQ. Today, Sunday the 14th, the second 70MHz Cumulative Contest runs from 1000UTC to 1200UTC. Using all modes, the exchange is signal report, serial number and locator. On Monday, the second FT4 series contest runs from 2000 to 2130UTC. Using the 80m band only, the exchange is your 4-character locator. On Tuesday the 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. The 70MHz UK Activity Contest is on Thursday also from 2000 to 2230UTC. Both are all modes and the exchange is signal report, serial number and locator. The BARTG HF RTTY Contest runs from 0200UTC on the 20th to 0200UTC on the 22nd. Using the 3.5 to 28MHz contest bands, the exchange is signal report, serial number and time. Also next weekend, the Russian DX Contest runs for 24 hours from 1200UTC on the 20th to 1200UTC on the 21st. Using CW and SSB on the 1.8 to 28MHz contest bands, the exchange is signal report and serial number. Russian stations will also exchange their Oblast code. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Friday the 12th of March. The bulk of last week saw settled geomagnetic conditions. Wednesday saw the Kp index at zero for much of the day, which is unusual. This was mainly due to a lack of disruptive coronal holes on the Sun’s surface, so the solar wind speed was mainly below 400 kilometres per second. The Sun was relatively spotless and at the time this report was being prepared, region 2807 was disappearing around the Sun’s edge, while region 2808 was appearing around the North-Eastern limb. Another tiny spot has appeared around the middle of the visible disk, but it doesn’t appear threatening and is likely adding very little to the solar flux index. The highlight of the week was probably the ARRL DX SSB contest last weekend, which saw plenty of stateside stations being worked. Chris, G0DWV said he worked California on 20 and 40m, plus Washington and Oregon. In fact, the only two states he didn’t work on 20 metres were New Mexico and Utah. A slender coronal hole, reaching up to the solar equator, looks like it could cause some disruption this weekend with the Kp index predicted to rise to four. NOAA predicts the solar flux index will rise from 70 on the 14th to 76 on the 21st. Don’t expect the quieter geomagnetic conditions to continue though. It will probably be a roller coaster ride next week, with the Kp index predicted to climb to five on the 18th and 19th. We said that it would be nice to have some more sunspots for this weekend’s 84th annual Commonwealth Contest, but it looks like we could be disappointed. But don’t despair, it is not unusual for stations from around the world to make an appearance, including many from Australia, New Zealand, Canada, the Caribbean, and more. The bonus is that there is no competition from DX hounds in non-Commonwealth countries. And now the VHF and up propagation news. A stormy end to this week, but signs of another spell of high-pressure next week. Stormy weather with its rain and blustery showers could be useful for some rain scatter on the GHz bands. The intensifying high should bring Tropo back on the menu as the week progresses and will also mean some quieter weather to repair any antennas that have suffered in the recent gales. This particular spell of high-pressure weather extends from the south-west, so it probably has moist air trapped under the inversion compared to a cold air high from the north and this could produce better Tropo conditions. We are still in the doldrums regarding Sporadic-E, but we are moving towards the spring months and April, and especially May, can bring some early Sporadic-E events, especially for those using digital modes. Moon declination goes positive tomorrow so Moon visibility windows and peak Moon elevations will increase as the week progresses. As we approach apogee on Thursday, path losses will reach a maximum then start to fall again. There are no significant meteor showers until the Lyrids, which peaks on the 22nd of April, so pre-dawn continues to be the best time for random meteor scatter contacts. And that’s all from the propagation team this week.

Full details of radio marathon and the five awards are on the Society’s radio marathon web page www.rsgb.org/ve-vj-marathon. As part of its Strategy 2022, the RSGB has just launched Beyond Exams, which is a group of resources to encourage participation and highlight the diversity of amateur radio. Beyond Exams includes awards and schemes to help amateur radio licence holders and clubs get the most from the hobby. During these challenging times of the global pandemic, Beyond Exams is an important part of the Society’s ‘Get on the air to care’ campaign in partnership with the NHS. Through Beyond Exams you can get on the air for the first time or try something new, a contest or CW, for example. Some of the activities won’t be available for radio amateurs to try due to the current social distancing regulations but there are plenty of others that can be done from the safety of your own home. For more information about how you can get involved in the scheme as a radio amateur or a club, see the RSGB website www.rsgb.org/beyond-exams. The 93rd Annual General Meeting of the Radio Society of Great Britain due to be held on the 25th of April in Birmingham was cancelled because of government restrictions on travel and public meetings due to the Covid-19 pandemic.

So far around 300 UK and non-UK participants have taken part, and for some it has been their first attempt at an HF contest. One participant told us that it was their first ever attempt at CW in 36 years. Come and join in the fun. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 1st of May. Sunspots are like buses – you wait all month and two turn up at once! Even more interesting is that the sunspot groups are from two different cycles. The first group, AR2760, was from the outgoing Solar Cycle 24 and the second sunspot, AR2762, is from the new Solar Cycle 25. We know this due to their magnetic signatures and the relative location of the spots on the Sun’s surface. AR2762 was a high-latitude spot, while AR2760 was almost on the solar equator. In any event, both spots were very minor and had little or no effect on the solar flux index, which hovered around 69-71. Geomagnetic conditions were more settled, with the Kp index remaining at zero or one towards the end of the week. The highlight for the week was the 2020 Summer Sporadic-E season on 10m, which is growing in strength. Stations in Gibraltar, Spain, Romania, Finland, Norway and others were all workable on 10m FT8 on Thursday morning, although it would have been nice to see a little more activity on CW and SSB, but more on that later. We expect solar activity to remain at very low levels in the short term, with the Solar Flux Index remaining at around 68-70. Geomagnetic conditions are likely to remain settled, other than this weekend when SWPC predicts the impact of particles from a solar coronal hole. NOAA disagrees and predicts that geomagnetic field activity is expected to reach active levels on Tuesday 5th May in response to a high-speed solar wind stream. It will be interesting to see who is correct. And now the VHF and up propagation news A small high crosses the country today and pauses over the North Sea on Monday, giving a Tropo option for most areas. This is soon followed by a further spell of unsettled weather with a good potential for rain scatter in the south over the middle of the week. Other weather models retain the high pressure, and even the unsettled model relents and brings another high to the northwest of Scotland, which will start to build across the country from the west to bring a fine, Tropo end to the week. As for Sporadic-E prospects, the next week does have some useful jet streams in good positions for paths from the UK. Early in the season paths can be fleeting, but keep a watch on 10m activity and then follow the opening higher in frequency as it develops on 6m, 4m and eventually 2m if we are very lucky. There is a big difference between FT8 and CW/SSB performance, but follow the many wonderful clusters and logging sites to see where the openings are. Try the daily Sporadic-E blog on www.propquest.co.uk to get an idea of the significant jet streams. It will have changes to the charts and a trial of the Sporadic-E Probability Index, or EPI. There is plenty to investigate in the 2020 Sporadic-E season. There are two meteor showers upcoming this week. The larger eta-Aquarids is on Tuesday and the eta-Lyrids occur on Thursday. Moon declination goes negative on Tuesday followed by perigee on Wednesday with lowest EME path losses. 144 MHz sky noise is very high today and for the early part of next week. And that’s all from the propagation team this week.

Using all modes in the respective bands, the exchange is signal report, serial number and locator. The 432MHz to 248MHz Trophy contest runs for 24 hours over next weekend from 1400 on the 2nd to 1400UTC on the 3rd. Using all modes the exchange is signal report, serial number and locator. Another 24-hour contest is the ARL International DX event from 1200UTC on the 2nd to 1200UTC on the 3rd. Using phone and RTTY on the 3.5 to 28MHz contest bands, the exchange is signal report and serial number, with Italian stations also giving their Province code. Next Sunday, the 3rd of May, the UK Microwave Group Low Band Contest runs from 0800 to 1400UTC. Using all modes on the 1.3 to 3.4GHz bands, the exchange is signal report, serial number and locator. The UK Six Metre Group’s Summer Marathon runs from the 2nd of May to the 2nd of August. Using all modes in the 50MHz band, the exchange is your 4-character locator. A one-off independent 2m contest is being held on Bank holiday Monday, the 4th of May, to promote 2m usage during the COVID-19 lockdown. From 2 pm to 3 pm, there will be an FM contest, where operators should exchange signal reports, serial number and 4 character Grid Squares. From 3 pm to 4 pm, there will be an FT8 contest using the standard FT8 messages to exchange signal reports and grid squares. The contests are open to all licensed amateur radio operators and short wave listeners but due to the Covid-19 lockdown restrictions, no portable or mobile operation is permitted. Further details can be found at www.vhflockdown.fun. And finally, don’t forget the RSGB Hope QSO Party on weekdays, see www.rsgbcc.org/hf for further details. So far around 300 UK and non-UK participants have taken part, and for some, it has been their first attempt at an HF contest. One participant told us that it was their first-ever attempt at CW in 36 years. Come and join in the fun. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 24th of April. Last week showed how difficult it can be to prepare HF propagation predictions. We said that we expected the Sun to remain settled throughout the week. But on Wednesday the 15th there was a stealthy slow-moving coronal mass ejection off the Sun that barely appeared in the SOHO spacecraft imagery. However, this CME was Earth-directed and around midday on Monday the 20th it hit. The net result was the Kp index rose to five and MUFs were adversely affected, after an initial positive phase that saw MUFs over a 3,000km path rise above 18MHz. HF conditions were still down on Tuesday, with bands above 20 metres pretty much closed. But luckily, by Wednesday things were pretty much back to normal. The highlight of the week has been a gradual increase in Sporadic-E on 10 metres. There have been numerous openings, mainly into Spain and the Canary Islands, with other fleeting openings into Sweden and Germany. While signal strengths haven’t been too strong so far, it bodes well for the Sporadic-E season, which is likely to ramp up over the next week or so. The message is - keep an eye on 10 metres. Next week NOAA predicts a continued quiet Sun with a solar flux index around 69. With zero sunspots predicted again it does begin to look like we are close to the sun spot minimum. Geomagnetic conditions are predicted to be settled, with a Kp index of around two to three, other than on Monday the 27th when it could rise to four. And now the VHF and up propagation news. We have a hybrid of weather types during the coming week, with the last of any Tropo fading as this bulletin goes out. Thereafter, it looks more unsettled with a chance of showery rain, initially in the southwest, but more generally as we run into next week. This is because an Atlantic low should develop south of Iceland and a cold front becomes slow-moving over western Britain at the end of next week. In this latter part of the week, high pressure builds from Biscay across northern France. So, expect some Tropo at first, but ending this weekend and perhaps in south-eastern areas late next week. Rain scatter looks more favourable again with several areas of showery rain or fronts involved from this weekend onwards. In view of the approaching start of the Sporadic-E season we would expect to find some openings, but as we said earlier any have been brief so far. It would seem that nobody has told the jet streams to get into line! I cannot say that this looks like a strong lead this week. The peak of the ongoing Lyrids meteor shower is over, so expect declining meteor scatter activity this week. Moon declination is positive all week and reaches its maximum on Tuesday. We are past apogee, so EME path losses will continue to fall. 144MHz sky noise is low all week. And that’s all from the propagation team this week.
The Lyrids are active all weekend, so you may see some tonight under dark skies, but the big peak comes early this coming Wednesday morning April 22, 2020. This year we're expecting 10 to 15 meteors per hour.
GB2RS NEWS Sunday the 19th of April 2020 The news headlines: Get on the air to care Cast your RSGB election vote SOS Radio Week to go-ahead The Radio Society of Great Britain, working in partnership with the NHS, has launched a campaign called “Get on the air to care” to support the emotional health and wellbeing of 75,000 licensed UK radio amateurs – just some of the 3,000,000 worldwide. It linked with World Amateur Radio Day yesterday, Saturday 18 April, which also celebrates this innovative, global community. Steve Thomas, M1ACB, General Manager of the RSGB explains: “Please help to increase amateur radio activity through club and repeater group nets, chatting with your friends or just by calling CQ. If you’d like to show your support for the NHS at the same time, Ofcom is happy for radio amateurs to add “/NHS” to the end of their callsigns.” GB1NHS, the UK’s National Health Service radio communications station will be on the air as part of this campaign so listen out for it! The Society’s new “Get on the air to care” web page includes the launch video, so go to www.rsgb.org/gota2c and take a look. Are you an RSGB Member? Have you used your vote yet? Don’t forget that voting for the RSGB elections is still open, although it closes at 9am on Thursday the 23rd of April. This is your opportunity to choose who you want to be part of the RSGB Board and help lead the Society over the next few years. The special web pages at www.rsgb.org/agm have details of the Calling Notice, Resolutions, candidate statements and information about how to vote. The voting results and trophy winners will be announced on the RSGB website on the 25th of April, when the AGM was due to be held. SOS Radio Week will go ahead, with all participants able to operate from home using either a special event callsign issued by Ofcom, a club callsign, or an individual’s own personal callsign. The event starts at 0000UTC on the 1st of May and concludes at 2359UTC on the 31st of May. During that period, participants should make as many contacts as possible with stations at home and around the world. For further details, and to register, please visit www.sosradioweek.org.uk. In many areas of the UK, all the HF amateur bands up to and including 20m are being blighted by interference from VDSL. This is the most widespread means of providing residential broadband internet services in the UK. Ofcom, which is responsible for investigating radio interference, says that it receives, on average, only six complaints per year on the topic and won’t take any significant action. The RSGB President has written a letter in the May edition of RadCom asking every radio amateur who suffers from VDSL interference to submit a complaint to Ofcom so that we can demonstrate the size of the problem. Please read the full RadCom feature and then look at the Society’s special web page, which outlines the process for reporting VDSL interference and offers you guidance and software to help you: it’s at www.rsgb.org/vdsl-reporting CQ-Serenade is a weekly programme for Northern European radio amateurs transmitted in the short wave AM broadcast bands. From the UK it is recommended to listen on 6160kHz during the daytime and 3975kHz at night. The weekly English language amateur radio programme has a new summer schedule and the program is transmitted at the times listed at tinyurl.com/CQ-Serenade. If you want to get your story or information on the air there, send your submissions to studio@shortwaveradio.de. ARISS has postponed school/group contacts in the USA as well as in South Africa and Romania. At least one contact in the UK has been cancelled altogether. In the short term, ARISS mentors will work with each school or organisation in the amateur radio contact queue to determine the way forward. It would rely on local government COVID-19 policy for guidance in deciding whether to cancel or postpone a contact or to modify the contact schedule. Several initiatives are in the works over the longer term to transform how they interact with students and host educational institutions in light of COVID-19 by engaging virtually with students and educational institutions. ARISS also is planning several slow-scan television sessions, during which images from the ISS would be transmitted to at-home students. Some sad news now. Marc Litchman, G0TOC passed away on the 29th of March. He had been in poor health for several months. He was a well-known RSGB volunteer who had supported the Society for a number of years. Our thoughts are with his family and friends. Bob King, G3ASE has also become a Silent Key. In 1941, Bob was recruited as a Voluntary Interceptor at the age of 16, followed by four and half years in the Radio Security Service stationed at Box 25, Arkley View, Barnet. There he examined logs from our intercept stations to determine which transmissions were German Abwehr and thus wanted. His work amongst the surviving VIs is legendary, including the annual reunions at Bletchley Park. Condolences to his family at this difficult time. Another Silent Key, Henry Pinchin, G3VPE, was the RSGB Regional Representative for Region 3 from July 1975 to December 1981. He served on the RSGB council from January 1982 to December 1987. We extend our deepest sympathies to his family. Obituaries for these well-known and admired amateurs appear on the RSGB website at. The RSGB has been adding updates to the ‘Sharing ideas’ section of its Coronavirus updates page, which you can find at www.rsgb.org/coronavirus-updates There are reports from Denby Dale ARC, Spalding ARC and Norfolk ARC, as well as news of two new technical videos on ATV and Microwave operations that the Society has added to its website. Find out what others are doing, be inspired and then email comms@rsgb.org.uk to share how your club is adapting to the current challenges. Now the special event news Peter, G4XEX will be active as GB4SAH for Stay At Home until the 30th of April to help amateurs pass the time during the lockdown. Euan, MM0VIK is active as GB1COR from his home QTH in the Shetland Islands, EU-012, until the end of April in recognition and support for the health professionals and essential key workers during the coronavirus emergency. QSL cards will not be available for this special callsign. Ten OH0 to OH9 special callsigns with the suffix PYSYKOTONA, which is Finnish for stay at home, are active until the 3rd of July. They’re to raise awareness for social distancing and remaining at home during the COVID-19 pandemic. QSL via Logbook of The World, eQSL, or via OH3AC. The RAF Amateur Radio Society will be activating the special event GB75VED from the 1st to the 28th May from members’ homes. Now the contest news Due to social distancing and movement precautions around the world, most contest organisers are not accepting entries from multi-operator groups or from portable stations. Check the rules before taking part. The First Machine Generated Modes contest ends its 24-hour run at 1400UTC today, the 19th. Using the 50 and 144MHz bands, the exchange is signal report and your four-character locator. The YU DX contest ends its 24-hour run at 0659UTC today the 19th. More information can be found at http://yudx.yu1srs.org.rs/2020. On Tuesday, the 1.3GHx UK Activity Contest runs from 1900 to 2130UTC. Using all modes, the exchange is signal report, serial number and locator. On Thursday, the 80m Club Championships takes place from 1900 to 2030UTC. Using RTTY and PSK only, the exchange is signal report and serial number. Next weekend the SP DX RTTY contest runs from 1200UTC on the 25th to 1200UTC on the 26th. Using the 3.5 to 28MHz contest bands the exchange is signal report and serial number, with SP stations also sending their Province code. Next Sunday, the 26th, the BARTG Sprint 75 contest runs from 1700 to 2100UTC. Using the 3.5 to 28MHz contest bands, the exchange is your serial number only. And finally, don’t forget the RSGB Hope QSO Party on weekdays, see www.rsgbcc.org/hf for further details. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 17th of April. Last week we said that we expected the Kp index to rise over the weekend due to incoming solar particles from an Earth-facing coronal hole. But we did warn that it was impossible to tell how severe it might be. In the end, it didn’t amount to much, as although the stream was travelling at up to 450km per second, its density was actually quite low and the Kp index topped out at a fairly low three. The Sun remained spotless all week and the solar flux index remained pegged below 70. The only good news was that we have begun to see signs of the impending Sporadic-E season, with one or two days showing short-skip openings on 10 metres into Germany and Spain, and a probable F2 layer or multi-hop Sporadic-E opening into Paraguay and Brazil on Thursday. We expect these to increase as we head towards May, so do keep an eye on 28MHz. The FT8 frequency of 28.074MHz will likely be the first to show signs of activity but don’t rule out the CW and SSB parts of the band. Next week NOAA has the solar flux index at or about 68-70. Conditions should remain settled until the 26th when the Kp index is predicted to rise to four, due to the return of a solar coronal hole. Propquest.co.uk shows that the daytime critical frequency (F0F2) is often exceeding 4MHz, so 80m and perhaps 60m are still best for inter-UK contacts. Twenty metres still remains the optimum DX band during daylight, with occasional openings on 17 and even 15 metres at times. Ten-metre propagation, when it occurs, is still likely to be via short-skip Sporadic-E, with very rare F2 openings bringing DX. And now the VHF and up propagation news. As high pressure tends to favour cooler areas at this time the year, it’s common to find highs over Scandinavia. Conversely, as the continent slowly warms, there is a tendency for low pressure to form, say, over France or Biscay. That is pretty much the typical pattern we find through next week. What this means for propagation is that the southern half of the country starts with showery rain or thunderstorms and the prospect of some rain scatter. This rain scatter option appears to last until about Tuesday. Northern areas nearer the high over Shetland and Norway could see some Tropo. This is because another typical feature of spring is that the North Sea is often covered by a layer of misty low cloud, and that makes good conditions for Tropo. So, look for paths along the east coast from East Anglia to northeast Scotland or across the North Sea to Denmark and Germany. Most areas see some Tropo benefit in the second half of the week. We are heading rapidly towards May, the nominal start of the Sporadic-E season. The position of the jet stream’s upper air patterns suggests that paths towards Spain and Portugal are more favoured, especially at first, with the second option of paths towards Scandinavia. Wednesday sees the peak of the ongoing Lyrids meteor so look out for increased meteor scatter activity this week. Moon declination goes positive on Tuesday but with apogee on Tuesday, EME path losses are at their highest this week. 144MHz sky noise is low. And that’s all from the propagation team this week.
The Lyrids are active all weekend, so you may see some tonight under dark skies, but the big peak comes early this coming Wednesday morning April 22, 2020. This year we're expecting 10 to 15 meteors per hour.

GB2RS NEWS Sunday the 12th of April 2020 The news headlines: IARU turns 95 EMC help is on hand Commonwealth War Graves Commission at NRC Saturday the 18th of April is World Amateur Radio Day, this year marking the 95th anniversary of the International Amateur Radio Union. Around the world, amateur radio special event stations will mark the event on the air, starting on the 18th at 0000UTC and continuing until the 19th at 2359. The theme this year is Celebrating Amateur Radio’s Contribution to Society and the COVID-19 pandemic casts the event in a different light than in years past. IARU President Tim Ellam, VE6SH/G4HUA, says “A few short weeks ago, many of us could not imagine the levels of isolation that we are now dealing with and the sacrifices of many on the front lines of the pandemic. As we have done in past challenges to our society, amateur radio will play a key part in keeping people connected and assisting those who need support.” Looking for help with an EMC problem? The RSGB’s EMC web page has a range of resources that will help including guidance on several EMC issues and helpful leaflets to download from www.rsgb.org/emc. The RSGB’s YouTube channel also has the RFI Clinic 2019 Convention lecture by the EMC Committee’s John Rogers, M0JAV and David Lauder, G0SNO. Take a look at the 2019 Convention playlist on www.youtube.com/theRSGB. A few weeks ago, the Commonwealth War Graves Commission visited the RSGB National Radio Centre at Bletchley Park to make a film about the B2 Mk III Spy set on display in the foyer. The video features RSGB member John Ellerton, G3NCN and can be viewed on YouTube. Go to https://youtu.be/U3ZZUJmItSU From the 13th of April, Matt, M0PTO will be uploading videos to YouTube for a new course called Lockdown Morse. The YouTube channel is at https://youtu.be/RWDqg8bCSqM. He has also created a Facebook page for the course at www.facebook.com/lockdownmorse. The RSGB has released onto its YouTube Channel a video by the Society’s Propagation Studies Committee entitled Understanding HF Propagation. It looks at sunspots, ionospheric layers, critical frequencies, solar flares and much more. You can see it at www.youtube.com/theRSGB Nordics on the Air was scheduled to be held this weekend. It has postponed because of the COVID-19 pandemic. On the youth NOTA camp, there would have been two HF stations with the callsign LA1YOTA spreading the voice of youth all around the world. Even though the camp is not going to happen there will be NOTA activation skeds from the 10th onwards. Look out for SK8YOTA on the 12th and TF3YOTA on the 13th. The RSGB HF Contest Committee has just completed a survey, which was open to all, to help determine its strategy during the COVID-19 pandemic. Questions focused on two issues. Firstly, how best to proceed with its flagship IOTA Contest in 2020. Secondly, whether or not there was a mandate for introducing a temporary HF contest series to provide some entertainment and support to RSGB Members and others who are currently staying at home. The committee had 656 survey respondents, of whom just less than half are regular RSGB HF contest participants. You can read the results at https://tinyurl.com/HFCC-survey-results. The RSGB has decided to postpone all Train the Trainers courses for this year. They had been planned to run up until July, so the team will start rescheduling them when the pandemic situation improves and full travel is restored. Icom has announced that delivery of the new IC-705 HF to 430MHz all-mode 10W transceiver, which was scheduled to be released in March, has been pushed back to later this year because the coronavirus pandemic has delayed the delivery of some components. More information will be posted on their website and via social media in due course. A long-silent repeater in Birmingham has successfully reactivated. GB3BM is on 145.7125MHz with 67Hz CTCSS tone. In the current situation of everyone being at home a great deal more than usual, this will no doubt be welcome news to amateurs in the area. Don’t forget that voting for the RSGB elections is still open. If you’ve struggled to find your Membership number, the Society has made it easier for you by adding it to the righthand sidebar of your Members’ page when you log into the website. This is your opportunity to choose who you want to be part of the RSGB Board and help lead the Society over the next few years. The special web pages at www.rsgb.org/agm have details of the Calling Notice, Resolutions, candidate statements and information about how to vote. Internet voting closes at 9am on Thursday the 23rd of April. The RSGB has a Coronavirus Updates page that brings together some great ideas as well as its important announcements. Take a look at www.rsgb.org/coronavirus-updates. Now the contest news Due to social distancing and movement precautions around the world, most contest organisers are not accepting entries from multi-operator groups or from portable stations. Check the rules before taking part. Today, the 12th, the First 50MHz contest takes place from 0900 to 1200UTC. Using all modes, the exchange is signal report, serial number, locator and postcode. The Worked All Britain Data contest takes place from 1000 to 1400 and 1700 to 2100UTC today, the 12th of April. All data modes except machine-generated CW may be used, but it is expected that most contacts will be by RTTY, PSK or FT8. The exchange is signal report, serial number and WAB square. Entries need to be with the contest manager by the 22nd of April. See www.worked-all-britain.org.uk. On Monday the Irish 70cm Counties Contest will run from 1300 to 1330UTC using FM and SSB. It is immediately followed by the 2m Counties Contest from 1330 to 1500UTC. This is SSB only. The exchange for both contests is signal report and serial number with EI and GI stations also exchanging their county. On Tuesday the 432MHz FM Activity contest runs from 1800 to 1855UTC. It is followed by the all-mode 432MHz UK Activity Contest from 1900 to 2130UTC. The exchange for both is signal report, serial number and locator.

The exchange is signal report and your four-character locator. The YU DX contest runs from 0700UTC on the 18th to 0659UTC on the 19th. More information can be found at http://yudx.yu1srs.org.rs/2020. And finally, don’t forget the RSGB Hope QSO Party on weekdays, see www.rsgbcc.org/hf for further details. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 9th of April. Sunspot group 2759, as reported last week, never really amounted to much and vanished before it got to the solar disk’s edge. The matter from a solar coronal hole did hit the Earth last weekend as we predicted, sending the Kp index to four in the early hours of Saturday morning. Even though we don’t have any sunspots, we are now benefiting from seasonal changes in the ionosphere and longer days. Monday’s 80m CW Club Championship contest saw the critical frequency stay comfortably above 4MHz, which guaranteed a lively event with high scores all round. Stations in the Netherlands, Czech Republic, Sweden and France joined in, which made for some head-scratching for amateurs expecting to hear mostly UK-based callsigns. But daytime on HF is still a little lacklustre as we continue towards sunspot minimum. Next week, NOAA predicts more of the same with the solar flux index pegged at 68 and zero sunspots. The Solar Dynamics Observatory spacecraft showed a large coronal hole was Earth facing on Thursday, which suggests we might get disrupted conditions over the weekend. Although we don’t know the solar matter’s expected Bz signature, if its locked-in magnetic field shows a strong south-facing Bz component we can expect it to couple strongly to the Earth’s magnetic field, resulting in a raised Kp index. So lookout for the possibility of a pre-auroral enhancement at first and then auroral conditions on 10m as it progresses. Meanwhile, there are signs that this year’s Sporadic-E season could soon warm up. Some Spanish low-power beacons have been spotted on 10 metres, but they are currently quite weak. We expect Es conditions to improve towards the end of April/early May with daily short-skip openings out to around 1,500 miles. So it is a good time to make sure your 10m antennas are working properly before the Es season starts. And now the VHF and up propagation news. In a general sense, this period of weather is essentially high-pressure driven except for a couple of brief incursions from low-pressure systems. Easter weekend sees the first visit by a low drifting from the north with April showers and some rain scatter potential. This is followed by a high moving from northwest Scotland southeast into Germany and again producing some good Tropo potential, which may well coincide with the 70cm UKAC on Tuesday evening, so a good result. The second half of the week models show a low moving from the south and affecting the southern half of the UK bringing some showery rain, perhaps thundery, so again some more rain scatter on the microwave frequencies. Lastly, the following weekend sees high pressure returning to Scotland and later the North Sea with further Tropo options. As we are pushing well into April we can expect to see the new Sporadic-E season developing in the next couple of weeks and the Easter Sunday 50MHz contest could well flush out any early stirrings! While we are still close to Lunar perigee, losses are low, but Moon declination is minimum on Tuesday. Moon visibility windows are just a few hours at low elevation, making EME difficult due to ground noise. Added to this is high 144MHz sky noise in the first part of the week, making it a poor week for EME. This Thursday sees the start of the Lyrids meteor shower, so we are coming out of the period of low meteor activity. Keep checking around dawn for the best random meteor contacts. Overall it’s a good week for activity on the VHF/UHF bands. And that’s all from the propagation team this week.
GB2RS NEWS Sunday the 5th of April 2020 The news headlines: G2HCG becomes centenarian this week Remember to vote in RSGB elections Foundation exams online during the pandemic A good news story to start this week’s news. The RSGB would like to wish Bill Sykes, G2HCG a happy 100th birthday for Wednesday, the 8th of April. Bill is well-known for his involvement with JBeam aerials and for his in-depth knowledge of aerials in general. He is still active, mostly on 80m slow-scan television. Don’t forget that voting for the RSGB elections is still open. If you’ve struggled to find your Membership number, the Society has made it easier for you by adding it to the righthand sidebar of your Members’ page when you log into the website. This is your opportunity to choose who you want to be part of the RSGB Board and help lead the Society over the next few years. The special web pages at www.rsgb.org/agm have details of the Calling Notice, Resolutions, candidate statements and information about how to vote. Internet voting closes at 9am on Thursday the 23rd of April. On the 20th of March, the RSGB stopped accepting new exam bookings as part of its response to the government’s guidance concerning Coronavirus. Since then, it has been exploring ways in which it can use the online exams platform to enable new people to access amateur radio and obtain their licence. Following rigorous tests, the RSGB is now able to offer remote invigilation for online Foundation examinations. The Exams Department will be ready to receive online bookings from Monday the 6th of April. Further information, including an update on practical assessments, is at www.rsgb.org/syllabus-updates. The RSGB has also published a FAQ about the new process for candidates and tutors, which is at www.rsgb.org/exam-faq. To help and support radio amateurs who are isolated at home and would appreciate contact with other people, the RSGB Contest Committees are launching a new six-week initiative: the Hope QSO Party. Starting on the 6th of April and open to every radio amateur, not just RSGB Members, this contest will also welcome international participation. Scoring is on an Anyone works Anyone basis. The format is a series of 90-minute weekday events for single operators. It commences on Mondays at 0830UTC, starting 90 minutes later each day to begin on Fridays at 1430UTC. A single-mode will be used each day, repeating over a 6-day cycle. The series will use defined frequency ranges; QSOs are encouraged before and after the contest periods. The series rules are at tinyurl.com/rsgb-hope. During the COVID-19 pandemic, with European national societies working remotely, several have said that their outgoing and in-coming QSL bureau can no longer provide services. Amongst those countries that have requested no QSLs be sent are Italy, Spain and Greece. The RSGB has released to its YouTube channel three more presentations from its 2019 Annual Convention. Board Director Kamal Singh, M0IOV explores The future and growth of Amateur Radio; Derek Kozel, MW0LNA talks about Digital Homebrewing and the Schematics of SDR; whilst Roger Balister, G3KMA and Igor, UA9KDF report on the Arctic Legends expedition by RI0B to the Russian Polar Arctic. Each of these presentations are not only interesting to watch on your own but could also form the basis for lively on-air club night chats during this time of virtual club meetings. The RSGB has a Coronavirus Updates page that brings together some great ideas as well as its important announcements. Take a look at www.rsgb.org/coronavirus-updates. Now the contest news Due to social distancing and movement precautions around the world, most contest organisers are not accepting entries from multi-operator groups or from portable stations. Check the rules before taking part. The First 70MHz contest runs from 0900 to 1200UTC today, the 5th. Using all modes, the exchange is signal report, serial number and locator. The UK Microwave Group second contest runs today, the 5th, from 1000 to 1600UTC. Using 1.3 to 3.4GHz bands, the exchange is signal report, serial number and locator. Also today, the 5th, the first RoLo, Rolling Locator, contest runs from 1900 to 2030UTC. Using SSB, the exchange is signal report and the locator received. The SP DX contest ends its 24-hour run at 1500UTC today, the 5th. Using CW and SSB on the 1.8 to 28MHz bands, the exchange is signal report and serial number, with SP stations sending their Province code. On Monday the 80m Club Championship CW contest runs from 1900 to 2030UTC. The exchange is signal report and serial number. On Tuesday the 144MHz FM Activity Contest runs from 1800 to 1855UTC. It is followed by the all-mode 144MHz UK Activity Contest from 1900 to 2130UTC. The exchange is the same for both, comprising signal report, serial number and locator. Thursday sees the 50MHz UK Activity Contest running from 1900 to 2130UTC. Using all modes, the exchange is signal report, serial number and locator. Next Sunday, the 12th, the First 50MHz contest takes place from 0900 to 1200UTC. Using all modes, the exchange is signal report, serial number, locator and postcode. The Worked All Britain Data contest takes place from 1000 to 1400 and 1700 to 2100UTC on Sunday the 12th of April. All data modes except machine-generated CW may be used, but it is expected that most contacts will be by RTTY, PSK or FT8. The exchange is signal report, serial number and WAB square. Entries need to be with the contest manager by the 22nd of April. See www.worked-all-britain.org.uk. And finally, don’t forget the RSGB Hope QSO Party on weekdays, as mentioned earlier in this bulletin. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 3rd of March. The high-speed stream of solar particles from a coronal hole on the Sun last week wasn’t moving as fast as we initially thought. As a result, its impact on Earth, and the subsequent rise in the Kp index to four, happened in the early hours of Tuesday morning and not the weekend as we predicted. The impact though was relatively short-lived and by late Tuesday the Kp index was back down to two. The bands were affected though, with the critical frequency as measured at Chilton struggling to reach 5MHz until midday Tuesday. The predicted MUF over a 3,000km path, according to Propquest.co.uk, looked like a roller coaster ride, often exceeding 18MHz, but then crashing down to below 14MHz. A smaller coronal hole is now facing Earth, which could mean a higher Kp index over the weekend, although NOAA isn’t indicating this. There is some good news though. A small sunspot group numbered 2759, appeared on the Sun’s surface, pushing the sunspot number to 12. This represents two sunspots, which accounts for the 2, in one group, which accounts for the 10. The spot’s high latitude suggests it is from the upcoming Solar Cycle 25. But on Thursday the SFI was still at a modest 69. NOAA predicts that next week the solar flux index will remain at about 68-70 and geomagnetically the Kp index will remain at about two. The good news is there are signs that the higher HF bands are remaining open longer. As the season progresses this should improve, with 30m and even 20m eventually remaining open until very late. We are also heading towards the 2020 Sporadic-E season, which should bring strong short-skip signals on 10m, but more of that in the VHF section. And now the VHF propagation news. The weather produced some half-hearted attempts at Tropo in the past week and even some weak Sporadic-E opportunities appeared on 10m and 6m. This week looks to be rather mixed in a weather sense. The high will weaken and drift east allowing low pressure to move towards northwest Britain from the Atlantic with a series of fronts crossing the country next week. This will offer the chance of April shower rain scatter at times and then, by next weekend, there may be a rebuilding of high pressure to the east with a hint of Tropo and warmth to end the week. The month of April is traditionally the start of early Sporadic-E on 10m and 6m via traditional modes like CW and SSB. For example, a weak jet stream over the Pyrenees mid-week could favour paths to IS0, EA6, EA5 etc. Remember that springtime is also a good chance to get some auroral activity, so check those Kp values: anything above four or five is interesting. Moon declination is positive until Tuesday, as is the perigee, so losses will be at their lowest. Moon windows will shorten as the week goes on. 144MHz sky noise is low, so in all, it’s a good week for EME. We are still in the annual low activity period for shower meteors until the Lyrids, which should start on the 16th of this month. Keep checking around dawn for the best random meteor contacts. And that’s all from the propagation team this week.
WATCH this on YouTubeLISTEN as a podcast on Podbean, Stitcher, or iTunes Social Media: @mrwebbpv on Twitter and Instagram @pvplanetarium on Facebook, Twitter, and Instagram Three planets still hanging out in the early mornings, an early month unusual conjunction, and a meteor shower make this time of socially distancing ourselves a great time to get outside at night! Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night. EVENTS... First Quarter Moon – 1st (Visible until midnight) Full Moon – 7th (Visible all night) Last Quarter Moon – 14th (Visible from midnight into the morning) New Moon – 22nd (darkest skies) First Quarter Moon – 30th (Visible until midnight) 2nd – 4th – Conjunction – Venus & Pleiades - You won’t see anything like this again until 2028, and it’s super easy to find! Just get out after sunset, look West, find the brightest object in that direction, Venus, which is about halfway up the sky. You’ll be able to see the mini-mini-dipper shape of the Pleiades star cluster in the same spot. See how many of those stars you can see with your naked eye! The 3rd is when Venus is right in the cluster, below the handle, but on the 2nd and 4th it’s still close by. You’ll be looking at two objects of very differing size and age. One a planet about 4.5 billion years old, the other a cluster of stars about 10 light-years wide and “only” 100 million years old. This is the time for binoculars or cheap telescopes, as Venus is easier to find in them, and the detail in the Pleiades really comes out in this modest equipment. 14th – 17th – Close Encounter – Moon, Mars, Jupiter, Saturn – Get out after 5:00am but before 6:00am DST each of these 4 mornings to enjoy, moving up and to the right, the lineup of Mars, Saturn, and Jupiter in the SSE, but also enjoy the Moon crashing through the party. The third-quarter Moon will be to the right of Jupiter on the 14th, right below Saturn on the 15th, about 4˚ down and to the left of Mars on the 16th, and, having turned more crescent, far to the left of all of them on the 17th. 22nd – LYRID METEOR SHOWER – It doesn’t get any better for observing the Lyrids this year! At only 10-20 meteors per hour, it is a minor shower, but we have a New Moon, so it won’t get drowned out by moonlight. So look North in general in the morning before dawn. The shower is greatest on the 22nd, but you might see some on the 21st and 22nd as well. Technically it peaks in the early morning hours, so getting up early is probably best, but it might be easiest to go out at night before bed. Just remember each meteor is piece of debris left over from a comet, and we’re crashing into it at over 100,000 miles per hour, which crushes the atmosphere it hits, heating it up and causing the bright flash. Some advice for watching: Find a dark location and lie down in a reclining chair or something that insulates you from the ground. Check the weather to see if the skies will be clear Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something. If you’re feeling extra nerdy, do a scientific meteor count (S&T and IMO) Or find out if your local astronomy club or museum is holding a viewing party. 26th – Close Encounter - Moon, Venus – Get out after sunset and watch the Western sky. The Moon will be a young, thin crescent about three finger-widths from bright Venus. The Moon will also be nearby Venus on the days before and after. Naked-eye PLANETS... Sunset Venus (West) – We are just past maximum Venus, as it reached its highest height above the Western horizon last month, but we still have two good months left of the sunset planet. Just watch the sunset and look West. Venus will be the brightest light and first object you see off in that direction. Through binoculars or a telescope, you’ll be able to see the half-lit phase of Venus in the beginning of the month turn into a bigger crescent phase by the end of the month. Don’t forget about it running through the Pleiades in the first week! Throughout the night – None Morning Saturn, Jupiter, Mars – The main show in the mornings is the lineup of these three planets. Get out well before sunrise (6:47am down to 6:00am at the end of April) any morning, and start by finding the brightest spot in the SouthEast, which will be Jupiter. From here, you can find Saturn and Mars. Saturn will be the bright spot that is consistently less than a fist-width down and to the left of Jupiter all month. Mars has a different story, starting out right below Saturn, just after their conjunction, and then moves further and further left each day, approaching 20˚ or two fist-widths away from Saturn by the 30th. CONSTELLATIONS... Use a sky map from www.skymaps.com to help you out. After Dinner: Leo, Orion & his winter companions – Leo will be high in the South, almost straight above you. It has a backward question mark with a right triangle to the left of the question mark. Also, take a moment to get your last glimpse Orion, Taurus, the Pleiades, Gemini, Auriga, and Canis Major off in the West. Before Bed: Big Dipper, Bootes – If you look above Leo, behind you and high in the sky, you should find the Big Dipper: seven very bright stars that form a spoon shape. Now if you take the handle of the Dipper, follow its curve to the next bright star you see, about 30˚ away, which is Arcturus. “Follow the arc to Arcturus.” That’s the brightest star in Bootes, which looks like a kite. Take that same curve, and follow it about another 20˚ to “speed on to Spica”, the brightest star in Virgo, one of my favorite constellations, since it reminds me of the Dickinson Mermaid. Before Work: Lyra, Hercules, Hercules Cluster – Look pretty much straight above you, and find the brightest star up there. You’ll notice a parallelogram attached to it. This is the brightest star Vega, part of the constellation Lyra, the harp. Next to that is a keystone shaped constellation called Hercules. On the right side of the keystone is a small cluster of stars known at the Hercules Cluster, which is a collection of hundreds of stars on the outskirts of our galaxy. Given how high it is in the sky right now, you might catch its faint fuzziness with your naked eye, but a set of binoculars or a small telescope will really help you see it.

GB2RS NEWS Sunday the 22nd of March 2020 The news headlines: Coronavirus affects amateur radio events worldwide RSGB Board changes AGM arrangements BATC offers free streaming & chat service There is no doubt that these are challenging times. However, licensed radio amateurs have a great way of keeping in touch with one another across the world. Clubs and groups are launching virtual meetings to make sure no-one feels isolated in the coming weeks. We have also seen radio amateurs step up with extra nets and repeater check-ins to provide welfare checks on all local amateurs. The RSGB has launched a new Coronavirus Updates page that brings together some of these great ideas as well as its important announcements. Take a look at www.rsgb.org/coronavirus-updates. RSGB General Manager, Steve Thomas, M1ACB explains more about how the RSGB is adapting to the fast-moving situation: “We took the decision to close the RSGB National Radio Centre earlier this week to help protect our staff, volunteers and visitors. You will also have seen announcements about changes to our AGM, exams and contests over recent days. During this difficult time, we have also been focused on protecting the welfare of our volunteer teams and the staff at RSGB HQ in Bedford. The majority of the sixteen RSGB staff are now working remotely but we will maintain a skeleton staff at the office, to receive deliveries, for as long as we can. Our staff have a very positive team spirit as they adjust to new working environments while we strive to maintain the usual services. We are still supporting Members and volunteers through the usual telephone and online services, so do continue to contact RSGB HQ in the usual way. Thank you for your support as we face these challenges together.” In response to the government’s latest Covid-19 recommendations, the RSGB Board has changed the arrangements for the Society’s AGM due to take place on the 25th of April. The physical meeting in Birmingham will not take place, and the information that would have been made available at the AGM will now be made available online. The Resolutions to be voted on are on our website at www.rsgb.org/agm2020 where you will also find links to the Board candidate statements and to cast your vote. You should continue to vote online as normal. The accounts will be published on the 1st of April on the AGM web page. As you will not be able to vote in person at the AGM, please remember to vote online by 9 am on Thursday the 23rd of April. If you do not have the facility to vote online, you can request a postal vote by contacting RSGB HQ. Postal votes must be returned to Civica Election Services, in the envelope provided, to arrive there no later than 9 am on Thursday the 23rd of April. Please bear in mind that postal services may well be delayed so leave plenty of time if you need to vote in this way. Results of the voting will be published on the RSGB website and social media channels on Saturday the 25th of April. Trophy winners will be announced on the RSGB website and social media channels on Saturday the 25th of April. Arrangements to present the trophies in person will be made later. We appreciate that the AGM is an important date in the RSGB calendar and some Members have attended it regularly for many years. But the Board cannot ignore the current health climate and put Members, staff and volunteers at risk by continuing with the AGM as intended. Every effort will be made to hold the AGM as usual in 2021. In order to support the worldwide amateur radio community during the Covid-19 virus pandemic, BATC is offering free use of the BATC Video Streaming Service and chat facility to any radio club or group of radio amateurs. This will enable clubs to hold virtual meetings with HD video and audio streaming and a chat window for real-time feedback and discussion. To enable this, the BATC is offering free one-year cyber membership to any radio club or group of radio amateurs. For details of how to apply, please go to the BATC website, https://batc.org.uk. Following on from the exam announcement earlier this week, it has been decided that with immediate effect and until further notice, the RSGB Exam Department will not be accepting or processing any new exam bookings. If you have already carried out a practical assessment for a Foundation or Intermediate exam and it is still valid, the period of validity – normally one year – will be automatically extended by the length of time that we are not offering exams. Exams already booked can, of course, go ahead at the discretion of the club, or can be postponed until a future date. The RSGB recommends that all clubs carrying out exams, training and practical assessments should carry out a risk assessment to ensure they are not putting themselves or candidates at risk. It is with regret that the HF and VHF Contest Committees have decided that, with immediate effect and until the end of June 2020, they will no longer accept multi-operator contest entries for any RSGB Contest. Single operator entries from shared stations will also not be accepted unless the station is being shared by family members living at the same postal address. The RSGB HF CW NFD Contest scheduled in June is cancelled for this year. They have decided not to ban portable operation by single operators because of the potential mental health benefits associated with engaging in hobbies as well as the lack of person-to-person contact in normal single operator contesting. However, they encourage everyone to follow the government guidelines regarding social distancing and unnecessary travel. They will review these rule changes regularly in line with the most recent government advice to determine if they need to extend or modify the restrictions. In early June they will decide if the VHF NFD, the IOTA Contest and SSB NFD can go ahead as planned. The RSGB band plans are now available in a number of formats online at www.rsgb.org/bandplans. The page also includes a background article that was published in RadCom earlier this year. If you have any questions, please follow the web links to the RSGB Spectrum Managers, who can help. Some advice from the Intruder Watch Co-ordinator next as the bands get busier. If you hear an HF intruder, please just note the date, time and exact frequency and report it to Intruder Watch, via email to iw@rsgb.org.uk. Amateurs should never transmit over intruding signals in an attempt to disrupt them, no matter how frustrating their presence may be. This can hamper regulators throughout Region 1, not just Ofcom, in gaining concise and accurate evidence. Finally, don’t forget, in the UK the clocks go forward 1 hour at 1am on the 29th of March, next Sunday. This means we will be on British Summer Time. And now for the details of rallies and events for the coming week Due to concerns raised over the Covoid-19 virus, many events in the forthcoming weeks are being cancelled or postponed. We will, of course, keep you posted as we learn of any updates during this rapidly-changing situation, and we will keep the Rallies page on the RSGB website as up to date as we can. Please check carefully before travelling to any event. So far we have heard that the following rallies have definitely been cancelled or postponed. March and April events that are cancelled include the Callington Radio Rally, the Yeovil QRP Convention, the MFARS Surplus Sale and Radio Meet and the Andover Radio Club Spring Boot Sale. March and April events that have been postponed are the CW Boot Camp at Stirling, the 23rd annual GMDX Convention, the Dover ARC Hamzilla Radio Fest and Electronics Fair and the Kempton Rally. Rearranged dates can be found on the RSGB website, at least for those that we get told about. Please send updates of your rally and event plans as soon as possible to radcom@rsgb.org.uk. And now the DX news Due to travel restrictions around the world-changing daily, we have decided not to include any DXpedition and similar news until the situation changes. Now the special event news Covid–19 is affecting special event stations too. GB1SCW was due to take place on the 7th of June from the National Coastwatch Institution facilities at Shoreham. However, the NCI has closed their watch stations until further notice. When there is more information, any updates will be shown closer to the event on QRZ.com. Now the contest news Running for 48 hours until 0200UTC on the 23rd, the BARTG HF RTTY contest takes place using the 3.5 to 28MHz contest bands. The exchange is signal report, serial number and time. Running for 24 hours until 1200UTC today, the 22nd, the Russian DX Contest uses CW and SSB on the 1.8 to 28MHz contest bands. The exchange is signal report and serial number, with Russian stations also sending their Oblast code. On Tuesday the SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 2.3 to 10GHz bands, the exchange is signal report, serial number and locator. Also on Tuesday, the IRTS 80m Evening Counties contest runs from 2000 to 2100UTC. Using CW and SSB, the exchange is signal report, serial number and County code. On Wednesday the UK and Ireland Contest Club 80m contest runs from 2000 to 2100UTC. Using CW only, the exchange is your four-character locator. Next weekend the CQ World Wide SSB contest runs from 0000UTC on the 28th to 2359UTC on the 29th. It’s SSB only on the 1.8 to 28MHz contest bands, with the exchange of signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 20th of March. Last week saw a continuation of the zero sunspot regime we’ve been seeing for the past few months. The solar flux index remained in the range 70-72, with settled geomagnetic conditions and with the Kp index remaining in the range of one to two. Thursday the 19th was the exception when the Kp index rose to four between midnight and 0300. This was undoubtedly due to a high-speed stream from a returning solar coronal hole, but it was relatively short-lived. The critical frequency graphs at Propquest.co.uk show that this had minimal adverse effects. This weekend marks the spring equinox, which is normally a good time for HF conditions. With equal illumination on both hemispheres, it is a good time for north-south paths such as the UK to South Africa, and the UK to South America. Predtest.uk shows that you probably have a 30-40% chance of making an FT8 contact with South Africa on 14MHz, perhaps even 18MHz, around 1600UTC this month. The path to Buenos Aires on 14MHz is similar, being optimum around 1900- 2000UTC. Next week NOAA predicts more of the same, with the solar flux index remaining around 70. Geomagnetic conditions should remain settled, other than on Friday the 27th when the Kp index is predicted to rise to four. And now the VHF and up propagation news. The coming week appears to be dominated by high pressure, so this will bring a chance of Tropo to many parts of the country, although it's not a very favourable-looking feature in a Tropo sense. There are three phases to this period. First, this weekend we are in the easterly flow, probably fairly dry air so not necessarily a good Tropo spell, especially with the brisk southeasterly winds. Secondly, into next week a cold front moves into northwest Britain and drifts southeast, disrupting the high pressure and any potential Tropo. The third phase, from midweek, sees the cold front weaken and high-pressure build again as a weak ridge across the country, which remains into next weekend. This may be a better prospect for Tropo, but still not a strong steer. As for the other exotic modes, Sporadic-E seems a relatively low probability and rain scatter in high pressure also tends to be rare. That just leaves the spring preference for aurora to keep us hopeful. We have a daytime Moon all week, with declination going positive again on Tuesday. Peak Moon elevations will continue to increase, but with apogee also on Tuesday, path losses are at their highest for the Lunar Month. 144MHz sky noise is low all week. With no major meteor showers due until the Lyrids at the end of April now, just keep looking for random meteor scatter QSOs around dawn. And that’s all from the propagation team this week.
GB2RS NEWS Sunday the 15th of March 2020 The news headlines: Voting for the RSGB elections is now open NASA Mars rover has a name Coronavirus affects amateur radio events around the world Voting for the RSGB elections is now open. The special web pages at www.rsgb.org/agm have details of the Calling Notice, Resolutions, candidate statements and information about how to vote. Internet voting ends at 9am on Thursday the 23rd of April. RSGB Members can find their Membership number on the wrapper of the latest RadCom so use it to vote before you compost the wrapper. The NASA Mars 2020 rover has a new name that captures the spirit of exploration, Perseverance submitted by a 13-year-old student from Virginia. Targeted for launch this July, this rover will search for signs of past microbial life on Mars. After landing in February 2021, it also will collect samples of Martian rocks and dust for a future Mars Sample Return mission to Earth. The RSGB is, like all responsible organisations, following government advice about the Covid-19 virus. The Society is still planning to hold its AGM in Birmingham but is ready to change these plans as necessary if advice about public meetings is upgraded. We will, of course, keep Members informed so please do check our website and social media channels for updates.The RSGB’s National Radio Centre welcomes individuals and large groups of people from across the world every week. With the increase in cases of coronavirus in the UK and other countries, the RSGB has taken the difficult decision to close the NRC temporarily from Wednesday 18 March. It will open as normal this weekend to run the ‘Build a radio’ events which are sold out, and the NRC will be open but without public access to the Radio Room on Monday and Tuesday. Whilst there aren’t any known cases of the virus at Bletchley Park or amongst the NRC staff and volunteers at this time, even with extra precautions it is no longer possible to guarantee the safety of NRC volunteers and visitors. We are very sorry for any inconvenience this may cause those who have planned visits but we hope people will understand the decision in the current fast-moving situation.Concerns over coronavirus and various advisories regarding travel and large group gatherings has prompted the cancellation of a popular international amateur meeting. The Visalia International DX Convention in California due to take place over the 12th to the 14th of April will no longer take place, see http://www.dxconvention.org/ for the latest news. Planning is underway for this year’s RSGB Convention that will take place from Friday the 9th to Sunday the 11th of October at Kents Hill Park Training and Conference Centre in Milton Keynes. The organising committee would like to receive your suggestions for this year’s lectures and workshops. Please feel free to email conference@rsgb.org.uk with your thoughts and ideas. If you are able to suggest a presenter, or a subject, for a lecture or workshop then so much the better. The RSGB Convention is generously sponsored by Martin Lynch & Sons. Dayton Hamvention has named the recipients of its 2020 awards. Steve Franke, K9AN, Bill Somerville, G4WJS and Nobel Laureate Joe Taylor, K1JT have been awarded the Technical Achievement Award. Amateur Radio on the International Space Station is celebrating the successful launch and docking of the SpaceX-20 commercial resupply mission to the International Space Station. One payload on the flight is the ARISS Interoperable Radio System, which ARISS calls “the foundational element of the ARISS next-generation radio system” on the space station. And now for the details of rallies and events for the coming week Due to concerns raised over the Covoid-19 virus, many events in the forthcoming weeks are being cancelled or postponed. Please check before travelling to any event. We will keep you up to date with news on events as and when we receive details. The committee of Wythall Radio Club have decided to cancel this year’s Wythall Hamfest, originally planned for today, the 15th of March. The Dover ARC Hamzilla Radio Fest and Electronics Fair due to take place on the 29th of March has been postponed. The CW Boot Camp at GM6NX Stirling due to take place on the 22nd of March and the 23rd annual GMDX Convention due to take place on the 4th of April have been postponed.

Next weekend from 0200UTC on the 21st to 0200UTC on the 23rd, the BARTG HF RTTY contest takes place using the 3.5 to 28MHz bands. The exchange is signal report, serial number and time. From 1200UTC on the 21st to 1200UTC on the 22nd, the Russian DX contest uses CW and SSB on the 1.8 to 28MHz bands. The exchange is signal report and serial number with Russian stations sending their Oblast code too. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 13th of March. A new sunspot group, numbered AR 2758 and from upcoming Solar Cycle 25, appeared this week. The region was located in the Sun’s southeast quadrant, but had faded away by Thursday the 12th. This was the first numbered sunspot region to appear in over a month as solar activity continues on at very low levels. Overall, the solar flux index remained at 70-71 with the geomagnetic Kp index being in the range zero to two, reflecting calm conditions. Wednesday’s RSGB 80m CW Club Championship contest proved just how inactive the Sun is at the moment. The contest started quite well, but soon everyone was struggling to make contacts as the critical frequency dropped below 3MHz as measured by the Chilton ionosonde. As a result, many contesters had to make do with QSOs with the Netherlands, Sweden and Germany as their higher-angle skip for local contacts failed to return to Earth. Daytime critical frequencies have often struggled to exceed 5MHz in the morning and 5.5MHz in the afternoon, meaning 40m remains unsuitable for NVIS-type communications. On DX, maximum usable frequencies over a 3,000km path have occasionally exceeded 21MHz in the daytime, but 18MHz has been more reliable. Next week, NOAA has the solar flux index pegged at 70-72 with quiet geomagnetic conditions, apart from March 19 when the Kp index is forecast to rise to four, possibly due to a high-speed solar wind stream from a returning coronal hole. And now the VHF and up propagation news. At last there is a signal in the forecast models for the return of some high pressure weather. After a prolonged period of windy and unsettled conditions, the first signs of a building high will come after this weekend as a ridge builds towards the southern UK from the Azores region. Eventually a new high, building in colder air over northern Britain, will probably take over in the second half of the week. Either way, it's time to consider the chance of some Tropo conditions later in the week, which will make a welcome change. It’s worth noting that the spring equinox is prime time for the possibility of aurora, so keep an eye out for high K indices as a ‘heads up’ for possible DX on the VHF bands. The Moon’s declination is at its most negative on Tuesday, so the Moon only reaches 13 degrees above the horizon. This means that ground noise is in the antenna lobes for much of the Moon window. Path losses are increasing throughout the week and 144MHz sky noise is very high for the next few days, so a poor week for EME. With no major meteor showers due until the Lyrids at the end of April now, just keep looking for random meteor scatter QSOs around dawn. And that’s all from the propagation team this week.
GB2RS NEWS Sunday 12th January 2020 The news headlines: First Tunisian licences in 6 decades Intruder Watcher DK2OM retires IET Wiring Reg changes affect Syllabus The IARU reports that the first three Authorisations to Operate have been issued to three Tunisian amateurs. These are the first amateur permits issued since 1956. 3V8HB, 3V8MN and 3V1MB will soon be on the air from their homes, rather than being restricted to operating from a club station. Issuing individual authorisations to operate is a new process in Tunisia and involves a number of stages, including equipment conformity checks. This is great news for Tunisians that the process now exists so that radio amateurs can practice their hobby from homes in full compliance with the Tunisian Laws. The IARU Member Society ARAT extends its thanks to the National Agency of Frequencies, the Ministry of Telecommunications and all involved parties for making this happen. After many years involvement in monitoring intruders on the amateur bands, Wolf Hadel, DK2OM, has decided to retire at the end of 2019. His work stretching back over 30 years first with DARC and, since 2005, for IARU Region 1, has been recognised with an IARU Diamond Award. Region 1 Vice-Coordinator Peter, HB9CET will take up the role on an interim basis until the Region 1 Conference in October. Changes to The IET Wiring Regulations, BS7671, which are now at the 18th edition, affect syllabus item 8A2 in the Safety section of the amateur radio examination syllabus. There is a notice at www.rsgb.org/electricalsafety that explains more – and it’s relevant to all three exam levels. Last week we told you about Ian, GM3SEK setting a new 70cm world record distance of 4,565km on tropo on the 28th of December. The record didn’t stand for long as Nick, G4KUX worked D21CV using FT8, establishing a new world record of 4644km. Congratulations to him. You will be able to read more about the excellent VHF conditions in the February edition of RadCom in the VHF UHF column. Any reports you may have for the column can be sent to radcom@rsgb.org.uk. The RSGB is looking for people to step forward for election at the RSGB AGM. There are vacancies for two elected Board Directors and six Regional Representatives. Full details of the nominations process can be found at www.rsgb.org/election. The deadline for your nomination is the 31st of January. To mark the 60th anniversary of the Republic of Cyprus members of the Cyprus Amateur Radio Society may use the prefix 5B60 during 2020 instead of the usual 5B4 prefix. The latest IARU Monitoring System newsletter for Region 1 is now available from www.iaru-r1.org. It contains detailed reports from the national coordinators within IARU Region, including the UK report compiled by Richard, G4DYA. In his report you can see where the Russian Kontayner Over The Horizon radar is appearing on the 40m band and the occasional broadcast station that appeared on the wrong part of the band. And now for the details of rallies and events for the coming week We have no details of rallies in January. The first couple of the year will be the Barry ARS Table Top Sale on the 1st of February and the South Essex ARS Canvey Rally on the 2nd of February. Please send details of your rally and event plans as soon as possible to radcom@rsgb.org.uk – we give you valuable publicity online, in RadCom and on GB2RS, all for free. And now the DX news from 425 DX News and other sources Sergey, RX3AMY will be active as 8Q7MA from the Maldives until the 23rd of January. This is a holiday-style operation and he will be mainly on 40 and 20m SSB. Jean, FG8NY, will be active with the special callsign TO10CWO from Saint Claude, Basse Terre Island in Guadeloupe, IOTA reference NA-102, between the 17th and the 31st of January. Activity is to celebrate 10th anniversary of CW Ops Club. Operations will be on various HF bands on CW. QSL via FG8NY. PP2OK, PY6ZK, PU6JEL and PY6TV will be active as ZW6C from Tinhare Island, SA-080, between the 16th and 19th of January. Activity will be on the 40, 20 and 10m bands using CW and SSB. Janusz, SP9FIH will be active as VK9NK from Norfolk Island, OC-005, between the 12th of January and the 12th of April. He will operate SSB, RTTY and FT8 in Fox & Hound mode on the 160 to 10m bands. QSL via Club Log’s OQRS or via SP9FIH. Now the special event news John, M0XIG will operate GB200FN until the 3rd of February to commemorate the 200th anniversary of the birth of Florence Nightingale. QSL direct to M0XIG. The British Amateur Radio Teledata Group is celebrating its diamond anniversary. Members of the Group will be active as GB60ATG until June 2020. More information can be found at bartg.org.uk. Please send special event details to radcom@rsgb.org.uk as early as possible. We have not received special event station info from Ofcom in recent months so you MUST let us know to get your event publicised here on GB2RS, in RadCom, and online. Now the contest news Today, the 12th, the Datamodes AFS takes place from 1300 to 1700UTC. Using the 3.5 and 7MHz bands, the exchange is signal report and serial number. On Tuesday the 432MHz FM Activity Contest runs from 1900 to 1955UTC, using FM only. It is followed by the all-mode 432MHz UK Activity Contest from 2000 to 2230UTC. The exchange for both contests is signal report, serial number and locator. On Tuesday the 70MHz UK Activity Contest runs from 2000 to 2230UTC. The exchange is signal report, serial number and locator. On Saturday the Worked All Britain 1.8MHz Phone contest runs from 1900 to 2300UTC. Using SSB only, the exchange is signal report, serial number and WAB square. Also on Saturday the SSB AFS contest runs from 1300 to 1700UTC. Using SSB only on the 3.5 and 7MHz bands, the exchange is signal report and serial number. Don’t forget that the UK Six Metre Group’s Winter Marathon and runs until the end of January. There are no specific operating modes or periods. Just work as many locator squares as you can on the 50MHz band. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 10th of January. Having predicted in last week’s broadcast that there would be no geomagnetic disturbances, we did in fact have two periods with an elevated Kp index this week. The first occurred on the 5th January, when the Kp index hit four. This was due to the impact of the solar wind. The Kp index rose again to four on Thursday the 9th, again due to the effects of a high-speed solar wind stream from a large geo-effective coronal hole. On Thursday a new spot was seen forming in the Sun’s north-east quadrant. This event, coupled with other recent reports of new solar cycle 25 sunspots, suggest that the cycle is starting to get under way. The next few months should give us a better idea of how it is progressing. Andy, M0NKR reports that he has now worked more than 100 countries since January 1, so there is DX to be had on HF! Meanwhile, ten metres was alive this week due to winter Sporadic-E. An opening at lunchtime on the 8th saw short-skip path openings on FT8 to Germany, Slovenia, Croatia, Latvia, the Czech Republic, Sweden, Finland and others. More on this in the VHF report. Interestingly, there were no CW or SSB signals on the band at this time. This just goes to show that you shouldn’t write 10m off at this time of year. Next week NOAA predicts the solar flux index will remain around 70, with mainly quiet geomagnetic conditions. We may have a geomagnetic disturbance on the 14th and 15th which could see the Kp index rise to four again. As always, look out for a pre-auroral enhancement at the beginning of the disturbance, but as it progresses expect to see lowered maximum usable frequencies and noisy bands. And now the VHF and up propagation news. As we recover from the excesses of Christmas Tropo and start a New Year, the weather continues to provide some interest. Firstly, the northern half of the country will be dominated by deep Atlantic lows, which will mean strong winds at times with rain or snow in the north and a good chance of further episodes of scatter paths on the microwave bands. The south will, for the most part, be on the edge of the main low track and there may just be a chance to link into the high pressure via Tropo, but this doesn’t look like a good option. Believe it or not, there is still one more roll of the dice for upper HF and VHF propagation and that may indirectly be the result of all this disturbed weather. The jet stream has been very strong, which is typical of winter months and, lying across the UK and northern Europe into Scandinavia, has produced some out-of-season Sporadic-E on 10m and 6m. Always worth a check, but the position of the jet stream and its strength may not be as favourable later in the week. Moon declination is still positive but declining, going negative again on Thursday. Path losses are at their lowest at perigee on Monday. This and the low 144MHz sky noise means a good week for EME. We are now entering the winter minimum of meteor activity, with just two more showers before the Lyrids at the end of April. Best opportunities for random QSOs will continue to be in the early morning around dawn. And that’s all from the propagation team this week.

What to look out, and up, for in June. This month we take a look at the constellation of Lyra the harp for the beginners guide – we have one of amateur astronomy’s favourite nebulas, M57 the Ring Nebula, hanging between the stars Sheliak & Sulafat like a suspended smoke ring and the Double Double stars – Epsilon Lyrae. Next we round up the planets that are visible in June: Venus, Jupiter in the evening & Saturn later on. Comet Lovejoy continues to put on a show for those with small telescopes and Comet Kopff tempt those with larger aperture telescopes. and the Lyrids in the low eastern morning sky. For our deep sky challenge we look at the constellation of Scutum the shield. We tour the Wild Duck and M26 open clusters, globular cluster NGC6712 and finish off with planetary nebula IC 1295.
What to look out, and up, for in May. This month we take a look at the constellation Ursa Major for the beginners guide – we’ll point you in the direction of an unaided eye binary star and a few of the brightest galaxies in the entire northern hemisphere sky. Next we round up the planets that are visible in May: Mercury (early in the month), Venus, Jupiter & Saturn later on. We take a look at Comet Lovejoy as it’s still visible in small telescopes, and the Lyrids in the low eastern morning sky. For our deep sky challenge we take you on a tour of Hercules’ magnificent globular clusters and a couple of overlooked galaxies.
Transcript: On a typical night you can see about one or two meteors per hour. Certain days of the year, however, the frequency goes up and you can see several per minute. These famous meteor showers are identified by the constellation in which they appear to come from. The most prominent meteor showers around the calendar year are the Lyrids which occur in the morning of April 21, the Perseids on the morning of August 12, the Draconids on the evening of October 10, the Orionids on the morning of October 21, the Taurids around midnight on November 7, the Leonids in the morning of November 16, and the Geminids in the morning of December 12.
