I saw this fireball while attending a film at Red Rocks Amphitheater in Morrison Colorado and was alerted to it's presence because others in the crowd began cheering. I looked above and to the left (North East) of the movie screen and witnessed about 2-5 seconds of the fireball falling. I would guess that many people in the audience observed this (possibly hundreds) as it fell for such a long time. Time enough for me to turn to and ask my wife if she was looking at it and then I was able to turn back to face it and still witnessed another second or two of it falling.
