Notes:
Left Image 05:00 U.T. (CM 135.8, IL/W30): The South Polar Cap (SPC) was brilliant and very small (more readily noticeable during moments of steady seeing). 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. Ambrosia (5/10) and Bathys (5/10) were noted to project from the southern border of Solis Lacus. Geryon (5/10) and Calydon (5/10) were noted to project from it's northern border. Aonius Sinus appeared dusky (4/10) with Phasis (5/10) projecting from it's northern border. Daedalia, Phaethontis, and Electris appeared bright (7/10). Mare Sirenum appeared dark to dusky (3-4/10) and mottled following the CM (Caralis Fons (4/10) was noted along it's following-southern border). A bright (7/10) streak was noted within Mare Sirenum along it's east-west length (possibly a cloud or dust?). Araxes was noted as a dull (5/10), diffuse projection over the preceding end of Mare Sirenum. Mare Cimmerium was diffusely visible within the extremely bright (9/10) morning limb haze (MLH). Memnonia and Zephyria appeared bright to very bright (7-8/10) north of Mare Sirenum. Tharsis and Amazonis appeared bright (7/10). Tempe and Arcadia appeared dull to shaded (5-6/10). Olympus Mons appeared as a bright (7/10) circular albedo feature over Tharsis preceding the CM. An extremely bright (9/10) evening limb haze (ELH) and North Polar Haze (NPH) were noted as well.

Right image 05:45 U.T. (CM 146.8, W38A): Solis Lacus, Mare Sirenum and Mare Cimmerium appeared dull (5/10). A very bright to extremely bright (8-9/10) cloud was noted to project from the preceding limb over Tharsis. Bright to very bright (7-8/10) clouds were noted over Memnonia and Zephyria. Extremely bright (9/10) evening limb haze (LH), morning limb haze (MLH), and North Polar Haze (NPH) were noted as well. A very bright (8/10) projection (cloud) from the NPH was noted over Tempe-Arcadia.
