LMP Hey, I just saw a flash on the lunar surface!

CC Oh, yes?

Geminids 12/13/1972

LMP It was just out there north of Grimaldi [mare]. Just north of Grimaldi. You might see if you got anything on your seismometers, although a small impact probably would give a fair amount of visible light. CC Okay. We'll check. LMP It was a bright little flash right out there near that crater. See the [sharp rimed] crater right at the [north] edge of [the] Grimaldi [mare]? Then there is another one [i.e., sharp rimed crater] [directly] north of it [about 50km]- fairly sharp one north of it. [That] is where there was just a thin streak [pin prick] [flash?] of light.

CC How about putting an X on the map where you saw it? LMP I keep looking for -- yes, we will. I was planning on looking for those kind of things....
