Terminal flash
ObservationYes
RemarksThe flash was very bright, like a mirror reflecting the sun. Immediately after, there were two bright trails coming off. The whole thing was over in 1-2 seconds. A smoke trail remained, approximately horizontal in the sky (it had some wiggles). I think the two big pieces also had smoke trails. The smoke persisted for about 90 seconds.
