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.
