Catena Abulfeda (David North <d _at_ timocharis.com>)
For the nth time, I rediscover Catena Abulfeda. The crater of the same name
is of little interest -- well formed with a smooth floor -- but there is a
very large "ray"structure leading off to the east, with a bit of a southerly
slope. Unlike more defined catanae, it also seems to incorporate a slump
valley, and at times looks more like a rille than a crater chain. In this
regard it reminds me of the more prominent Vallis Rheita. I guess this is
just one of those nights when everything I find looks like a smaller version
of another old friend.
Sacrobosco (David North <d _at_ timocharis.com>)
I can't travel this part of the moon without a stop at Sacrobosco, if for
no other reason than the name is so dang silly (Holy Chocolate Milk,
Batman!) The crater cooperates with the joke by looking silly, too. It has
three major impacts inside its somewhat indistinct walls, making it look
like a happy face with puckered lips. In a more serious vein, there were
some interesting albedo contrasts inside, which may just be a trick of the
light, or may imply some bright ejecta from one or more of the newer,
internal impacts.
