Re: Geminids

 

Hi John

Your capture is very interesting - it's a long time since I have seen such a long period of reflection. This is unlikely to be just a meteor trail AFAIK. It will likely be a meteor trail creating a patch of sporadic E ionisation which carries on reflecting the signal long after the original seed trail has gone.?

Tony?

Thanks for the info and link.

I had a listen this morning and I compared my reception to the receiver at the Norman Lockyer Observatory at Sidmouth. I caught one nice meteor scatter burst at 08:53 UTC which was about 45 seconds long.

The image on the left is from online receiver in Sidmouth and the image on the right is of my SpectrumLab display which is moving vertically at about a third of the speed.?The caveat of course is that maybe there were two separate meteor bursts at the same time but it would be some coincidence considering the low number of long bursts I receive.

There is about a 49 degree difference in heading from GB3MBA to Sidmouth and Cork so it's encouraging to see that signals don't seem to be restricted to a very narrow corridor for the 300-500km paths.?It'll be interesting to do some tests when Armagh goes live which will be 383kms at 293 degrees.

Just one thought... It would be useful if the remote receivers on the page were grouped by area. Maybe put all of the receivers to the west of the beacon on the left, the receivers to the east on the right and so on. It might make comparing traces a bit easier.
