Attached is an image I captured under very good seeing showing the progress of the storm that a lot of contributors have reported. I have included the image I captured on 13/11 to show the progression.
The dust is still prominent in Valles Marineris but it appears in the image that the dust is spilling out in the eastern half of the valley down towards Argyre Planitia then drifting west to cover Solis Planum, effectively closing the Eye of Mars. In addition there seems to be a concentration of the dust in the upper part of Solis Planum.
Thanks for looking.
