You also have to take into account, I think, the composition of the atmosphere around the meteor. (Here's a page on the aurora that I googled up, but the info should be fit for the ionization of atmospheric gasses by a meteroid, too http://www.wonderquest.com/NorthernLightsOxygen.htm). FWIW, I've seen plenty of fireballs that are green, and about the same apparent size and brightness as a round from a roman candle. ______________________________________________ Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
