Observation of Mars on 11 October 2005

  λ=304°Ls,  ( ω=110, 121°W,   φ=12°S ),   δ=19.0",   ι=23°


Notes:
Left Image 05:30 U.T. (IL / W30): The South Polar Cap (SPC) was very small and brilliant (10/10) surrounded by a dark (3/10) collar. Mare Australe appeared dusky to dull (4-5/10) and mottled. Solis Lacus was visible towards the preceding limb and appeared dark to dusky (3-4/10) with northern (Geryon (5/10) and Calydon (4/10)) and southern (Ambrosia (5/10) and Bathys (4/10)) projections over Thaumasia (7/10). Nectar (3/10) was visibly connecting Solis Lacus to Mare Erythraeum (3-4/10). Agathodaemon (Coprates) was visible as a dark (3/10) projection from the preceding limb connecting to a partially obscured, by clouds/haze (8/10), Tithonius Lacus (Melas Lacus (4/10) and Noctis Lacus (5/10); also comprising Echus Lacus, Hebes Lacus, and Ius Lacus which were not visible). Bosporos Gemmatus was dark to dusky (3-4/10) with condensations. Aonius Sinus (3/10) was visible on the CM with Phasis (4/10) projecting to the north. Phasis appeared to connect to a curvilinear and dusky (4/10) band from Tithonius Lacus which then completed a ring complex surrounding Solis Lacus. Daedalia appeared bright (7/10) between Phasis and Araxes (5/10). Mare Sirenum was visible following the CM and appeared dark to dusky (3-4/10). Sirenum Deprresio appeared a dark (3/10), circular albedo feature over the south-following border of Mare Sirenum. Phaethontis appeared bright to very bright (7-8/10) south of Mare Sirenum. The western (following) border of Mare Acidalium (5/10) was partially obscured by clouds/haze (8-9/10). Tharsis appeared shaded to bright (6-7/10). Arcadia and Amazonis appeared dusky to dull (4-5/10) and very mottled. A bright (7/10) patch was noted within this region which may represent the area of Olympus Mons (no specific brightening was noted over this area using the blue filter(W38A)). Dusky to dull (4-5/10) albedo features were noted over (or visible through) a semi-transparent North Polar Hood (NPH, 8-9/10). Thin and extremely bright (9/10) morning and evening limb hazes (MLH and ELH) were noted as well.

Right Image 06:15 U.T. (W38): The South Polar Cap (SPC) appeared small and brilliant (10/10). Solis Lacus and Mare Sirenum were visible as dull (5/10) albedo features. A very bright (8/10) W-cloud was noted over Tharsis, north of the Tithonius Lacus complex. Arcadia and Amazonis appeared to be obscured by a very bright to extremely bright (8-9/10) haze. Extremely bright (9/10) morning limb haze (MLH) and evening limb haze (ELH) were visible as well.
