(meteorobs) OT -Proceeding with IR block fireball detonationsystem.

[stange]

I recall Peter Jenniskens is investigating the "difficult to define" UV 
spectrum now and has written documentation of his findings. (Somewhere on 
the internet is opening remarks).

His work seemed to focus on the uv spectral lines of water and organic 
material possibly  imbedded in meteors/fireballs & maybe (comets?).

Certainly, people have set up meteor spectra cameras in the past. But unless
you use an image intensifier, they are pretty much limited to very bright
fireballs- which means you just don't get much data. I've never seen a
fireball spectrum published (but maybe somebody has one). A system using
filters, while not providing as good of spectral data as you'd get with a
grating, does have the advantage of providing a more continuous stream of
useful information.

Well, what about using a difraction grating? Just putting it in front of
the lens could give spectra of bright fireballs, or not? Maybe we could
get a -12 spectra per month or quarter. I see this better than the 3
channel low-res spectroscopy of the colour cameras.
