Briefly, here is my fireball observation and capture method as developed
thus far. It is a work in progress.
I am visually recording the whole sky from dusk to dawn with a video camera
(a HiCam HB-710E; lens is a Rainbow L163VDC4P fisheye ) into a Pansonic
VCR. On the first stereo audio channel of the VHS tape I am recording a
5 MHz WWV signal for audio time stamp and on the second stereo channel I
am feeding in forward scatter reception received from 83.250 MHz channel
6 transmitters. I am splitting the forward scatter signal into SpectrumLab
software which serves as my audio chart recorder. (The forward scatter receiver
is an ICOM PCR1000.) I go through the night's SpectrumLab charts and look
for any prominent meteor scatter reflections and then go to that time point
on the night's video tape to check to see if there is a local fireball capture.
I am pleased to find that significant line of sight fireballs do
make forward scatter reflections receivable in my radio system.
Following are spectrographs and fireball capture movies.
Below is a chart from August 27, 2007 which shows a strong meteor reflection
at 0836:40 UT. And here is a movie of the event. ( Note : Resolution
of this movie is a little crude and I am hoping to upgrade my equipment
to make better video specimens soon. North is at the top of the movie
frame, West is to the right.)
