予想外の晴れ間があり、あわてて最低限のショットは撮ってみたものの、シーイングは酷く、風も止まず、詳細は不明。

mage set from yesterday evening centred on the Amazonis region,with Propontis I at lower right and M Sirenum at upper centre.
The bright region (possible dust activity) near the NPC that I noted yesterday is not as obvious
In this set.A number of subtle clouds can be seen across the north.

I was lucky to make this recording just before the fog moved in. The brightening below the NPC,between CM and the p-limb,is difficult to interpret in this low resolution but at least it appears real. Note also the bright p-limb region at the equator.
In the south,now 3 haze patches appear,a distributed one at the morning terminator (prob. south/over Eridania/Electris),a concentrated one at the p-limb,and one at the very bottom (6 o'clock).
NPC is visible but only a very small streak.

I was able to get 3 rgb sets for this de-rotated relatively low resolution result,under persistently poor seeing conditions and with Mars rapidly decreasing in apparent size. Clouds are present in the south polar region and also apparently over Hellas. Morning haze covers the area NW of Syrtis major.

Interesting observation tonight: Is there a new dust storm starting in high northern latitudes?
In the first two images take note of the yellow band just framing the rests of an NPH. Normally there are now brighter yellow regions in the recent mars map, so this could be a dust band moving. Evidence for the existence of possible dust can be found in image three, where you can see yellowish clouds right at the limb, obviously drifting in the atmosphere and no ground albedo. Needs more observation in follow up evenings.
Otherwise typical haze at evening limb and in high southern latitudes.
