Capella and Toricelli (David North <d _at_ timocharis.com>)
Capella, a crater at the north of Mare Nectaris, has a remarkably outsized central peak (or so it appears). Near the terminator, two "wings" seemed to extend north and south and a bit west. Apparently they are just coincidental structures caused by nearby smaller craters and wrinkles. Made an odd impression, though.

Such low light also gave an odd look to Torricelli, with a similar "winged" look, made even weirder by the odd craterlet attached to its eastern edge. It was like some odd creature had been squashed onto the moon.

Torricelli Ray
There's apparently a Torricelli sunrise ray: see the L'ALPA page on the Torricelli ray (in Italian) for timing predictions.
Rimae Gutenberg (David North <d _at_ timocharis.com>)
Just to the west of Rimae Goclenius, the similarly intricate Rimae Gutenberg slashes to the northwest across some truly rough terrain, twisting and turning but not quite managing to penetrate the foothills to Mare Tranquilitatis. I suspect this is the easier of the two complexes, as it showed quite as well but the light was not as favorable.

Both share the characteristics of not being on the edge of a Maria, nor really in a mare zone... which makes them apostate. The classic rille structure is formed around the edge of a mare, or the edges and center of a large crater (probably a slumping effect). But here and there are some that cut right through the highlands. Perhaps the most spectacular example is Rima Sirsalis, but these groupings near Mare Nectaris and Tranquilitatis are in their own way equally as fascinating, in that they both have tripartite parallel runs.
