Hi Doug-
I don't think atmospheric extinction normally plays much of a role in
color perception of bright meteors. You don't get a full magnitude
difference between red and blue until you are about 15° above the
horizon, or about four air masses. And even at a magnitude difference,
I'd only

HI All,
Marco took the words out of my mouth. Getting tired of hearing that a green
meteor tells you anything
Meteor color is important. It's just not a very useful measure for
determining composition. Color changes with meteor speed and meteor
depth in the atmosphere. And certainly, the composition is a factor,
both in terms of chemical composition and bulk properties. But the
relationship is

A lot of folks say it looked green to them, which means it may have been
metallic;
It is a perpetuated misunderstanding that meteor colours are primarily due to
their composition. It's a science myth inspired by High School Bunsen burner
experiments that appears hard to kill.

The recent spade of very bright fireballs is due to the Taurid meteor stream by
the way, which every 5-6 years shows enhanced activity of this kind.
