Comments: This morning’s capture of Mars shows the iconic Syrtis Major and the Hellas Basin. This apparition has had its fair share of dust activity already, although these have been localised. There is quite nice detail here and it can be seen that the Hellas Basin is much clearer than it was a month or so ago, but that dust clouds are still partially obscuring it. They are quite thick across the Mare Hadriacum albedo area to its north and there is a hint of dust across Sytris Major itself. The dust in the area seems to have rusty red hue to it. This aspect is at perhaps 90 degrees to the one I captured recently with Sinus Meridiani central. Therefore the dark cleft that could be seen in that image is side on here. The brown colour is confirmed, although the red area seen in my last image cannot be seen here. It is likely that what we are seeing here is exposed surface where the ice has sublimated away and this is apparently not uncommon at this stage of the southern summer. There may of course be some dust activity in the region as well.
