I saw the fireball reflecting lots of light as it streaked vertically down. Then, when it was rather low in the sky, I saw a kind of flash (like one you might see if you lit magnesium on fire).
Fragmentation
Observation
Yes
Remarks
Directly following the flash of light immediately before the end of the event, I saw little reflective "pellets" fall away from each other quite quickly. There looked to be at least 5 or more distinct ones from what I recall. It was quite amazing and impressive.
