Watercolor of Mars
(black pen HB and blending stump on white paper plus coloration via Paint)
made with my Mewlon 250/2500.
The usage of the UHC filter imporve a little bit the contast through the storm.
Hellespontus and Hellas bassin were visible only with this filter,
out of that only the South area was detected.

The pre-dawn session centred on Arabia and S Sabeaus(what there is visible of it!) SPC is showing a bit of complex structure.

The attached shows a comparison of Mars three days apart.
In the latter image,the polar caps seem a little clearer.
Note that Olympus Mons (right) and Ascraeus Mons (left)
appear to be present as dark patches in the 4th of July image,
just north of the centre.
[Mark Lonsdale : [Canberra,Australia]
Dust storm still hide Mars surface,we can detect Syrtis Major,
Hellespontus,Mare Tyrrhenum and Hellas very bright.
Looks like that a left portion of SPC start be under a storm.
[Guilherme Grassmann,Americana-San Paulo,Brasil]
Hellas and Syrtis Major are prominent in this view,
and the dark areas N of the S Polar cap around L=300 are striking.
