Description

Seeing worsened a bit. Saharan dust limited transparency. Shortly after this photo, low clouds came in from the south, cutting off the opportunity to photograph Mars.

Notes:

  • The north polar hexagon is resolved.
  • The northern storm is stretched across the visible hemisphere of the planet. The storm appears to have two cores.
