The Artemis II crew just reported several impact flashes—explosions from hypervelocity impacts of meteoroids with the Moon—during the solar eclipse. We make a big effort to see a handful of these from Earth with telescopes. That astronauts flying by the Moon saw >4 in tens of minutes is AWESOME.

This is what a (fairly large) impact flash looks like on the Moon when viewed from Earth. This 12-frame sequence from the NELIOTA project in 2017 shows an impact flash that appears and fades over four frames. Credit: NELIOTA Project

NELIOTA saw 113 "validated" and 70 "suspected" flashes in 283.4 hours of observing time, i.e., one flash every ~2 hours. ">75% of the impacting meteoroids have masses between 1 and 200 g, radii between 0.5 and 3 cm and produced craters up to 3.5 m" www.aanda.org/articles/aa/...
