Shakespeare called Romeo and Juliet star-crossed because there was no hope for their love. Being Moon-crossed is not a commonly recognized condition (and isn't fatal) but it appears to mean being obsessed with seeing crosses along the terminator. Perhaps Tom is not obsessed, but he was pleasantly surprised to stumble upon one of the well-known crosses. Matching his image with sheets 55 and 65 from Jim Mosher's image version of Rükl's Atlas provides locational information. The cross is easy to find, if the terminator is crossing it, because it continues on a line from Aliacensis past Werrner. The cross is a clair obscur phenomena that can occur where ever two crater rims touch on an east-west line. Here the rims of Blanchinus and Purbach are reinforced to the north with La Caille, and Purbach's east rim has a high bump to help define the cross's center. Recognizing this cross does nothing to help understand the geology of the Moon, but it is a delight to see, especially if accidently observed.
