Although boring from the standpoint of few albedo features being visible, the atmospheric phenomena are interesting. The most prominent features are clouds, the largest being a pie-shaped wedge extending from Chryse along the east (preceding) limb through Tharsis. A circular cloud patch floats over Nix Olympica near the central meridian. Two smaller cloud patches are visible, one over Arcadia and a second over Elysium along the west (following) limb. The North Polar Region (NPR) is very small, barely 2" across. Mare Boreum circles the NPR. Mare Acidalium and Nilokeras are visible along the preceding limb. The sketch at left is based on the view in my 10-inch reflector at 388X.
