解説(安達)/ Comment by Makoto Adachi
I thought I would never see the stars again, but at last low clouds temporarily cleared up to reveal a banded cirrostratus sky with lunar halo and red planet. So pretty dismal, very humid and lightly foggy conditions this time, with unstable and varying seeing, which however resulted in this contribution.
The large northern cap appears visible in IR, and marginally in R, under a partially transparent hood which joins a wide morning limb arc. Perhaps the limb arc is a bit lighter at the extreme southern limb as well. No detached east-west cloud bands in the north, as was apparent a month ago. Albedo features look normal.
