Additional Information

Facula Caes, an exceptionally bright craterlet

Located near the upper right corner of this map is the officially unnamed high-albedo craterlet northwest of Sinus Honoris (Rukl 35) which is a noteworthy telescopic target during Full Moon (that craterlet looks very much like a "star"). It was photographed by the orbiting astronauts of Apollo 15 in the summer of 1971. In fact, there's nothing special to say about it whenever the LRO's extreme close ups are examinated (it's just a common bowl shaped high-albedo craterlet), but... it looks conspicuous during Full Moon! (there's a compact ejectablanket around that craterlet, looking like a very young, dense and bright nebula).
