I am a meteorite collector and have quite a bit of knowledge in astronomy and meteors. I was impressed by the steepness of this one's trajectory, and the fact that it clearly fragmented. This was the most impressive meteor I have seen since a huge fireball over Indiana in '77 or '78.

Remarks
I don't recall a flash although that may have been what caught my attention, I definitely saw that it was fragmented in a tight cluster of maybe 4 or 5 pieces. It may be noteworthy to add that ALL the fragments I saw stopped ablation exactly simultaneously.
