(meteorobs) OT -Proceeding with IR block fireball detonation system.

[Chris Peterson]

Paco-

Spectral analysis of meteor trails shows that emission lines dominate the 
light output. However, I think it is possible, or even probable, based on 
visual descriptions, that black body radiation dominates the output of 
bright fireballs (which haven't been studied spectroscopically). One way to 
study this question is by looking at the relative intensity at two or more 
wavelengths. While color cameras aren't ideal for this (I'm setting up a 
dual camera system with narrow band filters), it is still possible that 
useful information could be extracted from the individual color channels. 
The low sensitivity of color cameras makes them a poor choice for ordinary 
meteor monitoring, but that is no disadvantage at all if you are 
concentrating on fireballs.

Interesting Chris! What would we expect from the 3 colour data?

Thanks!
