South Polar Hood (SPH): Appears extremely bright (10/10) over the southern limb.

Sinus Meridiani: It's following (western) border appears adjacent to the evening (preceding) limb enshrouded by an extremely bright (9/10) evening limb haze (ELH).

Margaritifer Sinus: Appears dark (3/10) and triangular-shaped towards the p. limb.

Mare Erythraeum: Appears dark (3/10) with lighter (shaded, 6/10) regions consisting of Pyrrhae Regio and Protei Regio (preceding to following). A dark (3/10) bar (Arsinoes Depressio?) appears to divide Pyrrhae Regio and Protei Regio. Eos appears shaded to bright (6-7/10) north of Pyrrhae Regio.
