Chrysae, N. Lacus and Aurorae Sinus, APRIL 3, 2010





















I have finally managed to get a glimpse of the interesting Chrysae area and adjacent Niliacus Lacus and Aurorae Sinus on the opposite end. This observation had to be made as early as possible after sunset, since N. Lacus currently passes the central meridian at around 14:00UT.

Weather conditions were not optimal and no detail of the impressive "eye of Mars" - Solis Lacus was evident. Instead a hazy area comprising of Delphini Portus, S. Lacus and Aonius Sinus were visible with no evident features except a darker albedo for D. portus and A. Sinus.

Over Bosporos Gemmatus, a slightly blue haze was evident. The surface brightness of Chryse was lighter than Tharsis and Tempe regions.

On the North side, a hazy Niliacus Lacus was visible together with faint Nilokeras and Lunae Lacus. Tharsis and Amazonis regions were bright but showed no features, although a lighter area corresponding to Nix Olympica region was briefly detected with slightly improved conditions.

The albedo over Cydonia region was slightly lighter than adjacent Mare Acidalium. Also evident was the darker albedo stretching from M. Acidalium, Tanais and down towards the start of Nilokeras.

CCD images of Mars taken under better conditions using a larger scope (George Tarsoudis, Greece) close to my observation are here.
