Bright glowing train with green or maybe blue flashes or streaks
Terminal flash
Observation
Yes
Remarks
May not have been a terminal explosion because it preceded the glowing train, it started as a bright dot growing in brightness before quickly fading and producing a train
Fragmentation
Observation
Yes
Remarks
I don't remember details, only an impression of fragmentation into smaller and fainter dots or branching in the glowing train
