Notes:
Left Image 00:50 U.T. (CM 154.1, IL/W30): The South Polar Cap (SPC) was brilliant and small. Mare Austale was dusky to dull (4-5/10) and mottled. Solis Lacus appeared dark to dusky (3-4/10) over the south-preceding limb. Aonius Sinus appeared dusky to dull (4-5/10) with Phasis (5/10) projecting from it's northern border. Daedalia, Phaethontis, Electris, and Eridania appeared bright (7/10). Mare Sirenum appeared dark to dusky (3-4/10) and mottled on the CM (Caralis Fons (4/10) was noted along it's southern border). Mare Cimmerium was dark to dusky (3-4/10) following Mare Sirenum. "Valhalla" appeared as a dull (5/10) and diffuse band north of Mare Sirenum and Mare Cimmerium. Memnonia and Zephyria appeared bright to very bright (7-8/10). Tithonius Lacus was visible as a dark to dusky (3-4/10) wedge along the preceding limb surrounded by a very bright to extremely bright (8-9/10) cloud projecting from the extremely bright (9/10) evening limb haze (ELH). Tharsis and Amazonis appeared bright to very bright (7-8/10). Tempe and Arcadia appeared dull to shaded (5-6/10). Olympus Mons (orographic cloud) appeared very bright (8/10) over Tharsis preceding the CM. Phlegra appeared dusky to dull (4-5/10) towards the following limb (preceding Elysium). The southern components of the Propontis Complex (Euxinus Lacus, Propontis I, and possibly Castorius Lacus) were dusky to dull (4-5/10). Elysium appeared bright to very bright (7-8/10) adjacent to an extremely bright (9/10) morning limb haze (MLH). An extremely bright (9/10) North Polar Haze (NPH) was noted as well.

Right image 01:15 U.T. (CM 160.2, W38A): A very bright to extremely bright (8-9/10) cloud was noted to project from the preceding limb over Tharsis and extending to Memnonia. Mare Sirenum and Mare Cimmerium appeared dull (5/10). Olympus Mons (orographic cloud) was very bright (8/10) towards the north-preceding limb over Tharsis. Bright to very bright (7-8/10) discrete clouds were noted over Phaethontis, Electris, Memnonia, and Zephyria. Elysium appeared bright to very bright (7-8/10) over the north-following limb. Extremely bright (9/10) evening limb haze (LH), morning limb haze (MLH), and North Polar Haze (NPH) were noted as well.
