Dust Storm on Mars, Nov 24, 2020
At left is an image of Mars taken on November 24, showing the massive dust storm started few weeks after the planet opposition that is now affecting large parts of Mars' surface. At right, for comparison, a realistic simulation generated from the images taken weeks earlier with the same instrumentation, showing what would have been the aspect of the planet at the same time without the storm. Aside the normal shrinking of the polar cap it is quite striking the extension of the raving storm.
Good seeing condition, derotation of 3 videos, each of 120 sec per RGB channel. Diameter of the planet at date 15.7".
