The brightness of the south polar cap is muted by the dust storm. The cap also appears to have a hole.

CM1: 249.00°

CLat: -12.20°

Description

Seeing continued to be decent. Saharan dust limited transparency, but not as much as the previous night.

Notes:

There's a faint cloud above the dust storm in much of the southern hemisphere east of the central meridian.
Mare Tyrrhenum is hidden under a completely opaque part of the dust storm.
Mare Cimmerium is relatively visible compared to other dark features.
The brightness of the south polar cap is muted by the dust storm. The cap also appears to have a hole.
Hellas Basin is under a bright cloud of dust.
