Back in 1982, I saw a very bright flash on the Moon - naked eye! It was early Sunday morning (5.22 am) on July 18th. To this day, I'm not sure what caused it, and I've always eagerly followed up on any reports of 'transient Lunar phenomena', or, as in this instance, 'bright explosions'. I once spoke to Patrick Moore about it, with a full description (I remember him asking if it was summer time - yes, it was). He was similarly intrigued, and promised to look into it, but I never managed to follow up...
