Start/end points of the event were estimated from footage and may not be 100% accurate. In this case I struggled a bit to find stars in the footage, but start/end points shouldn't be too far off. Actual time of the event was 20:52:44UT +/- 5 sec. Duration was at least 181 frames (just over 6s). I did not visually observe this event.
