ObservationNo
Remarks-
Delayed Sound
ObservationYes
RemarksI heard a sound 20 to 30 seconds after the meteor broke up. Lasted at least 5 seconds. Volume changed several times. Sounded more like an explosion (crunching and cracking) than distant thunder (rumbling).

Remarks-
Terminal flash
ObservationYes
RemarksBlue streak started to fade and turn white or yellow, then a orange and red flash smaller than a full moon appears.
Fragmentation
ObservationYes
RemarksFragmentation was of different sizes and went in different directions, not in same trajectory as the blue streak. Fragmentation seemed to flutter like the end of a firework explosion. Not what I expected for a large distant object. Fragmentation lasted less than a second.
