Mars was shining high in the South. At 6 UT Amazonis was at the
CM position. This side has only a few dark details and since Mars is only
7"it might look the boring side . However,the big Tharsis volcanoes are
here,among them the mighty Olympus Mons. Olympus as well as the other three
volcanoes Arsis,Pavonis and Ascraeus can easily be distinguished by the
presence of their orographic clouds,in particular in the Blue channel. Also
note some details in the Northern polar cap.

Attached is a Mars drawing I made on 28th November 2011.
Doesn't show very much I'm afraid; seeing was very poor and there was a vast amount of dew!
I was stable able to make the attached disk drawing and the key points from the observation are as follows:
-Mare Sirenum in the far south, quite dark in places
-I suspected a brightening south of Sirenum
-I'm reasonable convinced there was a bright cloud on the proc. limb, and a bright cloud over Olympus Mons.
These two clouds may have been connected but in these conditions I was unable to be certain.
-NPC large and bright.
