(meteorobs) IR Signature of Meteors in the near IR

[Larry]

Hi Ed.
Using a Sentinel camera system (in its conventional form) for daylight work 
will not be effective. I found (2 years ago) a solution to the daylight IR 
trigger/contrast problem which unfortunately requires another Sentinel 
hardware system in a DEDICATED configuration distinct from our normal 
all-sky night monitoring equipment. That information has been passed on to 
interested parties and I will e-mail you particulars as soon as I get 
through munching last nights fireball data and sent images to Dirk in Tokyo 
& Eric's hunting group.
