Here's my latest observation of Mars, on the evening of the 10th (12th UT). I thought I would show it side by side with that of Jan. 4th, to show the evolution of the polar veils. The blue morning cloud in the southern polar region was very evident on the 4th, but I could not see any such thing on the 11th. Instead, there seemed to be a much fainter white/grayish curly wisp that ended in slightly brighter circular spot over the pole. The seeing was so bad, and the disk so small (9.4") that I had a hard time recognizing the main albedo spots so I may well have been wrong.
I have a couple of images from those nights (though different times) taken with an ASI 120. They are quite bad and the blue channel, especially, is always catastrophic but I thought it would be interesting to compare them to the drawings. The Jan. 4 image was taken in the worse conditions, with clouds coming and going but it still shows the blue polar cloud no problem. Nothing to see on the 11th, but the grayish wisp was a delicate feature which is greatly enhanced in the drawing, and the shape was also a bit different. I'm just no Chris nor David
