Not totally clear why this has only become apparent *since* 2005 - it’s not as if the moon is some obscure object that no one bothered to look at before. What kind of instrumentation is needed to see and catalog these flashes? Backyard telescope and a camera? Hubble telescope? Something in between?
Also wonder what, if anything, could be learned from the distribution of these flashes? Are they truly random, or are they biased in some way or another? If so what does that say?
