Description

I reprocessed my data from 12th August 2018 and was fairly pleased with the improvement versus my first effort with them. This is an interesting view because although the dust was clearing and albedo features which had been hidden for weeks were making their reappearance, there are still thick dust clouds at the central meridian and around the Tharsis shield volcanoes. Dust can still also be seen pooling in the canyons of the Valles Marineris near the eastern limb (left) in this image. Olympus Mons however, seems to be well clear of any remaining dust and had a very red colour at this time. White cloud appears just south of the north polar region at the bottom in the image. The very blue hue of this area is very clear. Already slightly gibbous the planet was 98% illuminated at this stage, but still retained a large apparent diameter not far off that of closest approach.
