[meteorite-list] color of lunar meteors

[Randy Korotev]

I suspect that for most meteors, the incandescent material is so hot 
that most of the light is from black body radiation, not electronic 
emission.  If so, then the composition is irrelevant.

I really don't know the temperature, though.

If composition is a factor, then I can't think of any reason why 
lunar meteors would be a significantly different color than 
asteroidal meteors.  All meteorites are low in Na (compared to earth rocks):

Na is a strong emitter and the cause of the yellow incandescence 
we're all familiar with (like, in sticking a piece of paper in a 
natural gas flame).  Lunar rocks have very low (sub ppm) 
concentrations of Cu (= green).  They're also much lower in Ni than chondrites:

Most lunar meteorites are not basalts, but anorthosites ("highlands" 
in figures),

which are rich in Al and Ca compared to chondrites:

Neither ionic Al or Ca is particularly "colorful" as an electronic emitter.
