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.

Awesome - hopefully another fall and a find - guys, get you boots on.
Is it true ?? Iron meteorites result in a green fireball??
