(meteorobs) Utah, Wyoming, Idaho Bolide 18NOV09

[Larry]

Hi Chris.

Wish I could have blown up your movie to take a closer look at that point of 
light that appears to have went behind that tree limb prior to the 
explosion. Good chance you and Thomas may have an incident match of the 
incoming Fireball in MHO.

To the question,
It is a suggested backup method of close Azimuth accuracy by photograph 
alone when permanent Astrometric calibration of the fixed camera FOV has not 
been done, and where not enough stars are visible at the particular time of 
the incident. Like my station.....
