South is up in this image, more info below.
At six days past new, the north western
portion of the moon is dominated by the pair Atlas and Hercules
just below left of center. Hercules contains a very deep cone
shaped crater inside, with a flat bottom. Atlas is known for
its dark volcanic out gassing spots inside its 53 mile width.
Above center is the shallow highly fractured crater Posidonius.
It is nearly 60 miles in diameter. The small mare just below
its north edge is Lacus Somniorum. The two dark terraced craters
on the lower right emerging from the darkness are Aristoteles
on the bottom, and Eudoxus on top, sizes 53 and 43 miles in diameter
respectively.
