Hellas was only moderately bright in red,with faint details visible on its floor.
In blue light a bright cloud covers the Hellas basin.

Attached are three Mars drawings I made on the night of the 10th-11th April. Although low passing cloud occasionally made observations awkward,we had some good seeing at times and I was able to use a power of x312.
Drawing 1 IL,2132UT CM: 233.5: Seeing average,x250 used. Mare Cimmerium nicely presented,the very edge of Syrtis Major coming onto the disk. The northern edge of the Mare Cimmerium appeared to be rather irregular with a long extension from Cimmerium in Aeolis. Aeolis and region immediatley north of Cimmerium appeared to be quite bright. There also appeared to be a bright cloud in Libya. Elsium was also quite bright,and there were darkish markings in Phlegra and Aetheria along with Prontis II and II. Boreosyrtis also well defined on the disk. In the far south Eridania was quite bright. NPC bright and Lowell band quite dark in places. Some subtle structure in Mare Tyrrhenum,Hesperia reasonably distinct.
Drawing 2 W#11,2217UT CM: 244.4: Used a W#11 (yellow-green) filter for this. The effect of which was to enhance the albedo features. View similar to drawing 1 except that now Syrtis Major is better placed.
Drawing 3 IL,0012UT CM: 272.5: Back to IL. Syrtis Major now on the disk properly. It seems that there is a cloud over Syrtis Major and Libya. Syrtis Major seems to have a distinctly bluish tint to it. IN the far south Hellas is bright (also a bluish tint present here?) The border of Hellas is rather dark. Similarly the Mare Hadriacum appears to be quite dark. Some nice subtle structure in Hadriacum and Tyrrhenum.
