Lunar impact flash - Geminid meteor

About this image

As part of a lunar impact flash project, I collected data of the uniluminated side of the Moon from about 2am to 6:30am on 13th December 2025. I recorded 5 minute video at 25 fps with an exposure time of 40ms and far too much gain... This resulted in 2.5TB of data in total. I've not been able to yet get the processing software to scrutenise my videos reliably, so am resorting to looking at the 7500 frames per video individually. Two of the three potential impact events, a faint very transient flash of light, have also been observed by at least one other observer which suggests these are impact events. The third of my potential candidates is awaiting someone else to verify if they picked it up too. A really fascinating project being in part run by Tony Cook, Lunar Section Director: https://lif.mi.imati.cnr.it/home_page.php?status=show_home
