I got a reasonable view of the western end of the dust storm last night. It is interesting that Argyre I and Campi Phlegraei were very bright and the whole region looked like a pseudo SPC. Evidence of dust can be seen in Eyrthraeum and Solis Lacus. It will be interesting to watch how the storm evolves and changes the albedo features. UK observes can examine the regions effected over the next few weeks.
