Lyrids April 2021_Radio Detection

Post by Carbon60 »

Complementary to Rainer's radio data, here are my data from the UK. I present mine in a different format to Rainer, so they don't look the same, but they do confirm the same result. The peak occurred on April 22nd.

Interestingly I did detect a couple of additional 'bursts' leading up to the peak Lyrids in which the hourly rate significantly increased for short periods. I don't believe this is radio interference as the parameters measured match what would be expected for meteor detections (signal strength, duration and echo frequency), so maybe these are breakaway patches of space dust. If anyone has information on this, I'd be happy to hear from you.

Here's what I recorded for April 21st, the day before the peak. Here you can see the cumulative count through the 24hr period with two identified 'burst' in the count rate.

Thanks for looking.

Hi Stu,

Great. If You look at my Colorgramm on 21st there are also some peaks (yellow color).

I assume that it UTC time in your graph, OH well, UK is UTC :lol: :lol: :lol:

Would be interesting to see your data also in rmob.org ;)


regards Rainer

Just to add another scenario Guys, the attached image is just one frame taken from my All-Sky-Camera (times etc., inset), which I wonder if travelling approximately from SE to NW could still be a Lyrid or actually a Meteorite - which could have landed somewhere in the NW-U.K.

Stu, would your detection-gear have picked-up on this one ??

Cheers
Terry

Great results Stu, interesting with that sporadic peak. I guess the Lyrids aren't going to be great visually unless you're somewhere with really dark skies.

Many thanks, Rainer, Terry, Mark and Alexandra.

Terry, I’d have to check my data. Identifying a single event might be tricky, especially with the inevitable computer clock lack of synchronisation. Mine isn’t connected to the internet, so I have to rely on the internal clock, which isn’t precisely correct.

Thank you Stu. My computer clock is usually checked against the MSF/DCF standard time clocks, so within about a second or two, the times on the image as GMT/Z/UTC should be correct... Certainly within 1-minute..

I've still got several frames of that event to try and form an animation, but that frame shows the meteorite well-enough for the purpose.

Regards
Terry
