There have been several reports of a possible impact flash in the Byrgius-Lagrange area of the Moon, near the western limb, during the 21 January eclipse. It occurred at 04.41 UT and several observers managed to capture images of the event. There will be a full report in the February Lunar Section Circular, but in the meantime I would be grateful if members could check any images or video captures taken around that time.
