Nick,
did you also manage this one from early this morning a mag -5.4 a similar ground track to the other I put up a few days ago.
I’m pleased I took this aspect of astronomy up, one never knows what has been caught overnight and it adds a bit of excitement to breakfast. The data is useful as well.
I’m also surprised how much can be caught on what may be a poor night when other types of observations are not taken up. A few minutes of clear, even a misty break in the clouds. Most days it seems I capture something.
Regards,
Eric

After a week of no electricity in the area of the Observatory which shut us down, we are back rockin’ and rollin’
. Looks like the same capture.Well done Michael, I have my radio detector disconnected for the past few weeks. I have it working but really now need to fix it outside the house away from interference . I need some more guidance on how to use it and in interpreting what I see.

Here is what was captured in Hayfield, Derbyshire using a radio station tuned to GRAVES with Spectrum Lab
and here is the Doppler shift and power profile from Meteor Logger
There is no head echo but it otherwise looks like a classical overdense power profile.

Hayfield in High Peak
Is there any confirmation of the flight path please? As a radio meteor observer using the GRAVES radar it is not often that I find a video capture with trajectory that correspond to a radio event. This is important because the coverage of the radar is largely unknown. If this were over Kent it would be the futherest North I have had!
I caught it from Chelmsford and would be happy to run the other stations’ data through UFO orbit to get a groundtrack when their data is available.
Nick,
I’d be happy to forward the data to you. Which of the files from UFO analyser do you need.

Eric has provided me with his data. The geometry is not very favourable since our stations are too close together but here is the ground track. It was out over the English Channel off the north coast of France.
Thanks to Nick for making use of my data with his to provide a better ground track position. It was good to see the actual end result.
Thanks for direction Nick. This is definitely useful information in helping me extend what I know of the coverage of GRAVES radar. The scatter is from lobes from the rear of the antennas. The end of the trail crosses the Great Circle line between my monitor receiver and the transmitter close to Dijon and is just about midway between. The power profile I recorded suggests it is specular scatter which, because of where, implies it is at a fairly shallow entry angle.
Thanks again Nick and Eric – keep them coming!

…’Americo Watkins asked about a ‘Previous fireball’ to the Exploding one. If he gives me the time and date I will see if i have anything.. Further..’mike.german’ ..the disappearance of Power and Doppler in your graphs..is with the Eye of Faith..to be seen in the video track in attached shot’.I Attach a frame from my video of the event..and as my location is ‘Lngtde Offset’ from Nick and Eric hopefully this will help the accuracy of the path..I usually monitor UK Met on twitter for daily meteor mentions and IMO for others.. If Eric let’s me know time date of his previous interest Meteor I will see if i captured it too.. Apols for lack of immediate clarity but thought to Real time my input.

My guess is that few members would expect to receive information via this method?I Attach a frame from my video of the event..and as my location is ‘Lngtde Offset’ from Nick and Eric hopefully this will help the accuracy of the path..I usually monitor UK Met on twitter for daily meteor mentions and IMO for others..
