Terminal flash
Observation Yes
Remarks The fireball was descending, getting brighter as it fell and faded quite abruptly. It did not flash bright enough to cast shadows or pop the sky like a flashbulb but it did get significantly brighter at the end of its flight. I had a distinct impression of an asymmetric shape. The leading edge appeared somewhat flattened and the trailing edge had "tips" extending back from the fireball. The general impression was somewhat like a home game machine controller, somewhat rectangular with the tips extending backward.
Fragmentation
Observation Yes
Remarks At least two or three distinct fragments separate from the main fireball.
