Hello Folks After a few hiccups the Live stream to YouTube is currently operating again. Search for "GB3MBA Live Stream" on YouTube. It will not be operating 24/7 as the receiver hardware and PC providing the stream are required for other duties. I will try to keep the stream live for a period around the peak of the Perseids on the 12th August. Later in the project development we hope to provide a more reliable stream to YouYube. Meanwhile the project live stream of all active receivers is a more reliable way of seeing the activity of the receivers in the network. This is at https://ukmeteorbeacon.org/beaconclient/ This continues to show meteor echoes at a rate of 2 per minute or more across the day with the highest rates from 00:00 to 12:00z. Thanks to Dave Jones at the Norman Lockyer Observatory that receiver is back in operation and the faulty unit will be coming back to me for investigation and repair. Brian

Hello Folks We are now testing the YouTube live stream from one of the UK Meteor beacon Project receivers. To view go to https://www.youtube.com/@GB3MBA/streams There are plenty of interesting echoes as I write this. We plan to activate this stream during the Perseids meteor shower. I will leave it on test whenever possible in the mean time. (The PC running the stream does have other duties sometimes ). Brian

TO MARCUS LEECH: Hi Marcus, Any chance I could ask for copy of this software from you? My email is andrew@... Andy From: sara-list@... <sara-list@...> On Behalf Of Jonathan Pettingale Sent: 02 July 2024 01:48 To: Society of Amateur Radio Astronomers <sara-list@...> Subject: [SARA] Kraken SDR and Interferometry Today I did a 23-hour drift scan, using 2 homemade cantennas, 12 feet apart, feeding a Kraken SDR. The Kraken was controlled using the "Modified BAA Seminar" software kindly provided by Marcus Leech. Cantennas are standard design for 1420 Mhz, with a Sawbird LNA, mounted at the feed point. The time axis is hard to read but starts at 0106 UTC, the big bump is the Sun! These are early days, much needs to be done regarding calibration and sensitivity, but the aim is to make a 5-element interferometer.

An 'off-the-chart' month for solar activity, and for the consequential consolidation and reporting work. Many thanks to John Cook for his work on this! Paul Hyde

These dishes are looking rather nice. https://www.crowdsupply.com/krakenrf/discovery-dish/updates/latest-manufacturing-news Tony

Hi Radio Astronomy Section Zoom Monday the 10th June Paving the Way: Next-generation Developments in VLBI Dr Jack Radcliffe – UK SKA Regional Centre (UKSRC) research scientist at the University of Manchester and senior lecturer at the University of Pretoria Video is now on YouTube here You can find links to previous meeting videos and associated materials here Kind Regards John B

Paving the Way: Next-generation Developments in VLBI Dr Jack Radcliffe - UK SKA Regional Centre (UKSRC) research scientist at the University of Manchester and senior lecturer at the University of Pretoria The Zoom room will be open from 19:15 BST (18:15 UTC). Zoom link will be sent out Friday 7th June In the past few decades, surveys using radio telescopes have provided us with unique insights into many areas of astrophysics such as star formation, supernovae, active galactic nuclei, pulsars, cosmology and much more. A key aspect of these surveys is the technique of Very Long Baseline Interferometry (VLBI) which can provide some of the highest resolutions possible in astronomy. This method has made crucial discoveries in many areas of astrophysics and geodesy including cosmology, galaxy formation and evolution, the innermost regions of active galactic nuclei, explosive phenomena and transients, stars and stellar masers in the Milky Way, celestial reference frames and space applications. In this talk, I shall review some of the discoveries made using VLBI, and highlight the exciting developments coming from existing and new instruments such as the ngVLA, next-generation Event Horizon Telescope and the Square Kilometre Array. If you want to be added to the Zoom Distribution list please let me know. -- ¦¦¦ Paul Hearn ¦¦ paul@... ¦¦ RA Section Director ¦¦

Next stage of the eruptions around Grindavik has started. The uplift in the surface has reached record levels over the last week or so, suggesting that this might be the most energetic episode yet. Paul Hyde

Hi All, I had a brief conversation with John Cook at the BAA Winchester Weekend about the feasibility of using a Raspberry Pi, SDR dongle and appropriate software to detect meteors, he suggested I post here. The last time I did meteor detection I was using a custom script I’d created in SpectrumLab (see here https://crayfordmanorastro.com/radio/meteor-observations-with-radio/) with an X86 laptop and handheld scanner. At the time, I had investigated using a Raspberry Pi but they were pretty new, x86 software wasn’t compatible and the project didn’t go anywhere. Since then, USB SDR Dongles have been invented, Raspberry Pis are now on version 5 and the Pi 5 is significantly more powerful than the Win 98 Laptop I was using, has more memory, faster disk and network access etc. Windows has also come to ARM, I believe there is a Just in Time (JIT) re-complier that recompiles x86 software on the fly (JIT compilers are very fast), but I have no experience of this, also Linux SW has developed a huge amount so there might even be a mature Linux software solution (my main Laptop is Linux). Anyway - I’m now thinking of trying again, creating a meteor detector to compliment the visual meteor detector my Astro Society (Crayford) already runs. The concept is a Raspberry Pi, USB SDR, and appropriate software. I’d save the files to a NAS with remote cloud access so members can share any post processing/collation for reporting purposes. Do you know if anyone is already doing radio meteor detection on a Raspberry Pi? If so can you point me to the details? I’m also interested in compatible USB SDR’s and Compatible Analysis Software (like Spectrum Lab) I’d like to know this is possible because I don’t want to reinvent the wheel and I don’t want to spend my societies cash finding out it can’t be done! :-) Thanks, Simon.

Hi All, Please can you look at the question I have posed here on this link (on link so I can upload associated graphs to make question clear) – what are your thoughts? https://astronomy.me.uk/lro-sid-monitoring-graphs-at-23-4khz-from-10-11-5-2024-when-the-aurora-was-seen-in-my-garden-lichfield-uk Andy
