    This happened a while ago now, but I was wondering if anyone had logged something similar on the same night. On Saturday, 5 August 2017, 2:00 – 3:00am, I saw a bright flash of light right in the centre of Grimaldi. I was using a 130mm Newtonian and about a 220x magnification. It may have been a meteor strike. Interestingly I discovered that focusing in the general area of Grimaldi was difficult for several minutes afterwards. It wasn’t elsewhere. Suggesting some sort of ejecta.

    Telescopes: One Newtonian, three Maksutov Cassegrains, seven refractors, and a large SCT.

    David – are those times GMT or BST, and roughly what was your geographical location. If you were observing from the UK the Moon would have been pretty low in the sky on that night. This would increase the chances of the explanation being due to a red flashing navigation light on a very distant aircraft, and you would not necessarily notice the aircraft if it were very distant. Impact flashes can also sometimes be red, but are really incredibly rare if they were to be seen against the illuminated side of the Moon.
