According to “Spaceweather”:
“A METEOROID HITS THE MOON DURING LUNAR ECLIPSE: On Jan. 21st at 04:41:43 UT, a meteoroid slammed into the Moon. We know this because so many people witnessed the explosion. It happened during a total eclipse of the Moon, visible from five continents.”
Did anyone catch it?
