  λ=252°Ls,  ( ω=212, 218°W,   φ=20°S ),   δ=10.4",   ι=47°


Notes:
Left image: An observation of Mars made at 06:50 U.T. under integrated light (IL) and also using a magenta (Wratten 30) filter. The South Polar Cap (SPC) appears brilliant (10/10) surrounded by a dark (3/10) collar comprised of Mare Australe, Thyle I and II, and Mare Chronium. A very dark (2.5/10) albedo feature was noted at the approximate location of Ulyxis Fretum (190*W, -63*). The regions of Electris, Eridania, and Ausonia appeared to be partially obscured by a bright (7/10) haze (water-ice clouds/ low-lying fog?). Mare Cimmerium appeared dark to dusky (3-4/10) with it's southern border partially obscured by the bright (7/10) haze. Mare Tyrrhenum and Syrtis Minor also appeared dark to dusky (3-4/10) following the CM. Elysium was visible over the north-preceding (Np) limb and appeared to be obscured by a bright (7/10) haze. Cerberus/Pambotis Lacus/Eunostos I (4-5/10) were visible along Elysium's southern border. Zephyria, Aeolis, Aethiopis, and Aetheria appeared bright (7/10) without any detail visible within. An extremely bright (9/10) evening limb haze (ELH), North Polar haze (NPH), and morning limb haze (MLH) was noted as well.

Right image: An observation of Mars made at 07:15 U.T. using a Wratten 38 (blue) filter. A wedge-shaped bright (7/10) was noted to extend between Electris, Eridania, and Ausonia (water-ice clouds/surface fog?). A bright cloud (7/10) was noted over Elysium. The evening limb haze (ELH), North Polar haze (NPH), and morning limb haze (MLH) appeared extremely bright (9/10). The South Polar Cap (SPC) region appeared extremely bright (9/10) as well.
