I witnessed a bright flash on Sunday morning while I was at the Naylor Observatory. Unfortunately, I was inside the French Dome at the time and didn't see what created the light. I happened to be looking through the shutter opening around 12:26 a.m. EDT when the entire eastern sky was brightly illuminated for a split second.
Note: the questions regarding the direction of the trajectory do not apply since I saw only a terminal (?) flash. The figures shown are incorrect.
