Comments: The iconic Syrtis Major is just on the f side of the CM and to its south is, of course, the Hellas Basin, which has now resumed its more normal golden colour after many weeks/ months of obscuration by clouds of dust. The southern border of the basin is not as well defined as the rest of this largely circular basin suggesting that some dust is present there. To the north of the Hellas Basin is Mare Hadriacum. There are clearly dust clouds right across this albedo area and they appear to have defined bands in places. Some fingers of these dust clouds appear to encroach on the Hellas Basin. Towards the ever shrinking SPC there is more evidence that cascades are in progress and the rapid sublimation of CO2 is, it seems, driving wind borne dust in the f and p directions. The SPC clearly has two parts and the island sitting to the north at the CM is Novus Mons
