The South Polar Cap still appears to be muted by the dust storm.

Mars UTC

CM1: 245.10°

CLat: -12.00°

Description

Seeing remained excellent. After this photo, I took some time to view Mars through a Celestron Luminos 23mm eyepiece, which I affectionately call the "Beer Can Eyepiece". The difference in color between the South Polar Cap was surprisingly striking to the eye. Dark albedo markings were barely visible.

Notes:

  • Syrtis Major is rising.
  • The atmosphere above Mare Cimmerium appears to be less opaque than surrounding areas.
  • Hellas Basin has a few yellow clouds streaking over it.
  • The South Polar Cap still appears to be muted by the dust storm.
  • Most of the SPC also appears to be darkened.
