Re: Watching meteorites fall on the Moon
Hello List,
Good thread here, and Gene I'd like to see what you have. I have been looking for a reference for an account I read some time ago, but don't recall enough accurate details to search. The account goes something like this...
A "medieval" monk in Europe , perhaps France, was recording the features on the moon when one night he observed "fire on the moon" (with his unaided eye perhaps, but later details indicate this was with a telescope). He was hesitant to recount his observations for fear losing his credibility. It came to pass that another monk or nobleman, etc. also saw something too. Subsequently, there was a new huge crater observed, TycoB comes to mind.
Does anyone with a searchable database have this account?
Regards,
Elton
