[meteorite-list] Utah, Wyoming, Idaho Bolide 18NOV09

[Chris Peterson]

Virtually all slow, bright fireballs are green. The color comes from 
atmospheric oxygen. Any green lines from iron would show up 
spectroscopically, but not visually. There is no way to determine 
composition from visual color. This was apparently breaking up over a long 
distance- I estimate at least 300 miles. So my bet would be on a stony body.
