Notes:
Left Image 00:45 U.T. (CM 277.5, 6" F/15 Refractor): Mare Cimmerium appears dark to dusky (3-4/10) preceding the CM. Hesperia appears as a light (7/10) division between Mare Cimmerium and Mare Tyrrhenum. Mare Tyrrhenum and Syrtis Minor appears dark to dusky (3-4/10) following the CM. Mare Chronium appears dusky (4/10) preceding the CM towards the South-preceding limb. Eridania and Ausonia appear shaded to bright (6-7/10). Mare Hadriacum appears dark to dusky (3-4/10) over the eastern (preceding) border of Hellas (8-9/10). Iapygia Viridis appears dusky (4/10) and Syrtis Major dark to dusky (3-4/10) towards the following limb. Aeolis and Aethiopis appears bright (7/10). Libya appears bright to very bright (7-8/10, haze?). Very bright to extremely bright (8-9/10) haze is visible over the south polar, preceding (evening), north polar, and following (morning) limbs.

Right image 01:05 U.T. (CM 282.3, 10" F/9 Newtonian): The above description (00:45 U.T.) applies to this observation with the addition of a greater clarity of albedo features. The Hyblaeus Extension (4-5/10) was visible towards the northern limb. The preceding (eastern) portions of Hellespontus (4/10) and Sabaeus Sinus (3/10) were visible over the following limb.
