Seeing was very variable this evening.
The region is very similar to the region imaged last night. The Tharsis Volcanoes can be seen sticking out of the clouds on the left. Albedo features are not as resolved as yesterday's image.

Very poor conditions recently,but here's an image from last night showing
Syrtis Major. Elysium is very bright.

Captured throug a thin layer of fog ore cirrusclouds in gaps of thicker
cummuliclouds. I had to use very long exposertimes (1/38 sec instead of
1/108 sec in blue),so the noisy images show not a lot of details and
image processing was very difficult...

The seeing was poor. The Syrtis Blue Cloud was visible as well as a brilliant Elysium orographic on the PM limb. There were also clouds over Aeria and Libya-Isidis.
Hellas appeared dull in red light and was apparently overlaid with cloud rather than frost.

Some very good seeing on this night. Here is a set of RGB images and also a detailed B image i obtained that despite the rapidly dwindling apparent diameter showing some delicate cloud structures across the disk. The Olympus cloud appears brilliant.
Images from the April 13th session clearly show the southern high altitude limb cloud again. I've attached a G filter image showing the feature protruding above the SW limb.
