Thomas,

Playing the video repeatably(can't make the loop work in your video), does 
show a moving point of light in the exact same direction as the flashes that 
occured on your horizon. It looks like you (DID) catch early footage of that 
fireball.

Chris and all,

Thanks for your analysis.

I have now processed my secondary video and I believe the video does
show the actual fireball just before the terminal flashing.  But, since
the distance between my observatory and the meteor's flight path is so
great  ( 300 miles and further) I hesitate to say for sure if this is
the actual fireball. It could be a coincidental meteor?  The flashes
that follow are definitely the Utah fireball.  I have further videos
with WWV  that give precise timing at November 18, 2009  0707:17-21 UT.

If this preliminary video does indeed show the trajectory it will be
helpful in triangulating.

Video in two formats:
.mp4  750 KB  :  http://www.heliotown.com/FB20091118_0707Radio_Ashcraft.mp4
.wmv  2.8 MB    http://www.heliotown.com/FB20091118_0707radio_Ashcraft.wmv

This particular video document also has VLF/ELF radio recorded which
shows no obvious emission in this case and also VHF forward scatter
which may exhibit a minor reflection.

Hoping for more data.
