Mars November 20th, dust storm

Mars on November 20th: after twilight the seeing was horrible, the dust storm could be detected only as a yellow smudge. Later that night the air briefly stabilized and some more detail appeared. The tail of the storm was dim on the west rim of the planet, over the southern Solis Lacus area.
