2. Nice fireball...actually observing one is a fairly rare occurrence.

A fireball is another term for a very bright meteor, generally brighter than magnitude -4, which is about the same magnitude of the planet Venus as seen in the morning or evening sky. A bolide is a special type of fireball which explodes in a bright terminal flash at its end, often with visible fragmentation.
<snip>
Several thousand meteors of fireball magnitude occur in the Earth’s atmosphere each day. The vast majority of these, however, occur over the oceans and uninhabited regions, and a good many are masked by daylight. Those that occur at night also stand little chance of being detected due to the relatively low numbers of persons out to notice them.

Additionally, the brighter the fireball, the more rare is the event. As a general thumb rule, there are only about 1/3 as many fireballs present for each successively brighter magnitude class, following an exponential decrease. Experienced observers can expect to see only about 1 fireball of magnitude -6 or better for every 200 hours of meteor observing, while a fireball of magnitude -4 can be expected about once every 20 hours or so.

4. They said on the news this morning that the fireball was green..

I wonder if that could tell what elements/gasses were included in it.

7. The green color is usually an indication of Copper in the composition

11. That makes sense.

When you solder copper pipes you get green flame.

5. Wow! That Was BRIGHT!!!

I saw a high light meteorite once, about 10 years ago. It wasn't that big or that bright, though.
