Satellite Flash (18:29)

Satellite Flash Satellite Track / Flash recorded whilst acquiring a 60s exposure of transient target AT2023abtv (blue circle) Satellite evidentally rotating, and a flash of sunlight is reflected towards the Observatory Site Flash is relatively is relatively minor and is barely recorded, if at all, by the AllSky Camera. The event is not in the same league as an Iriduim Flash , but is notable as it has been captured in the Telescope CCD Images
