Here are two screenshots showing reflections lasting just under two minutes.? Some might? call this sporadic E but a meteor head echo was clearly seen by the NW Hampshire receivers on the first

Thanks for the info Andy, I'll read the docs. Larry, K4WLO

Hi Larry The UKRAA site has had a few updates in the last few days, including this today. I will being adding an announcement to th frnt page later to day. The new PicoMuon can can be found here

Paul, I went to the UKRAA website but didn't find any information on either price or availability of the muon detector.???? How might one acquire that info? Larry, K4WLO

As many of you will know UKRAA is a charitable enterprise run by volunteers. ?We exist to support the amateur Radio Astronomy community with kit and software to enable astronomical observations. ?We

The SID at midday was from an M1 flare, listed in the SWPC satellite data, but it does not show anything after about 17:00. This strange event at 19:00 does seem to have been widely recorded. John

I have received the e-mails about the strange SID so I checked back to see what I had recorded. I've attached a screen shot for the 20 April which may show a small SID around the time you are talking

I also detected the.minor.magnetic disturbance at 1900 but I think that was just the precursor for the very unsettled magnetic period on the 20th.? Nothing seen on vlf though. -- -- Martyn

Yes, it was your magnetometer I was referring to, Roger, when I said there was a slight disturbance.. As for the GPS problems, unfortunately they don't give a time for it, so could have been the

My magnetometer shows a slight disturbance from about 1900 UT onwards. -- Roger Blackwell GM4PMK www.marsport.org.uk

I have just seen on the space weather web site that some severe GPS disturbance was also seen on the 20th. No timings given, so maybe another coincidence? John.

Hi Andrew Unfortunately I am not really able to give much in the way of time as I am fully occupied on a PhD and day time job. However, I think if the project is to become

Thanks for the charts. It certainly looks as though something disturbed the ionosphere at that time, but what caused it is the question. It was just before sunset for the paths to Anthorn and

Hi Mark I did capture a SID-like disturbance peaking 19:06, but I probably wouldn't have reported it as it's within the sunset chaos.? Chart attached.? The glitch at around 18:40 is my induction

Sorry, I included the wrong image. John.

Hello, ??? ??? My chart does show a 'SID' at 19:07 on 23.4kHz and 19:04 on 22.1kHz. The magnetometer shows only a minute change, but it is a single axis compared to The 3-axis on Mull. My
