(meteorobs) Possible radio signature of Geminids - preliminary research

[Thomas Ashcraft]

I have been noting a possible characteristic radio reflection signature 
of Geminids during peak nights the past few years. Geminids may exhibit 
weaker variety head echoes and slightly delayed reflections.   I have 
many more specimens to process and maybe a pattern will emerge.

Each movie below is about 3 MB.

Two simultaneous Geminids with VHF scatter:

By contrast here is a probable December Leonis Minorid fireball with VHF 
scatter the same night.  Faster meteor with stronger head echo.

Much more processing to do.
