The "Rukl" numbers refer to charts in Antonin Rukl's Atlas of the Moon, widely acclaimed by lunar observers as the best lunar atlas for the telescopic observer. Long out of print, the second edition has been recently reissued by Sky Publishing. The "L" numbers refer to the feature's position in the Lunar 100, where applicable. The Lunar 100 is an observing list covering the 100 most significant features on the Moon, ordered by difficulty.

Rukl 44, 55. A great night for sketching these craters! Situated nicely on the terminator. High clouds made view hazy but didn't really interfere. I caught a nice wrinkle ridge running through the floor of Alphonsus, as well as the craterlet Ammonius on the floor of Ptolemaeus. Even got Herschel along for the ride. Sadly, Rimae Alphonsus was in shadow.
