Terminal flash
ObservationYes
RemarksThe 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
ObservationYes
RemarksAt least two or three distinct fragments separate from the main fireball.
