Terminal flash
Observation Yes
Remarks Brightness and size increased significantly (double?) when last seen on the left eye field before disappearing. At that time or shortly before, the tail or part of it was still visible.

The hundreds or thousand of shooting stars I have seen did not behave this way, and extinction (or end) was a simple disappearance, and not an increase in size.
Fragmentation
Observation Unknown
