© Alexander Massey This sketch is of one of the brightest features on the Moon, the crater Aristarchus. The brilliantly illuminated internal western wall requires time to spy out the many fine details within it, otherwise these features would be washed out. A myriad of riles radiate out from this crater.
Wedged between Aristarchus and the terminator is the crater Herodotus. Its incompletely illuminated eastern wall seems to extend out to form one end of the serpentine valley Vallis Schröteri. This meandering valley sees the highlighted valley wall bounce around from side to side with the change in direction of the meander.
Again I chanced upon very stable conditions to be able to see such fine detail. This is one of my favourite sketches I’ve done.
