解説（安達）/ Comment by Makoto Adachi
Misty in the south,possibly subduing Bosphorus〓Gematus and Thaumasia a bit.
Solis Lacus and Aurorae Sinus a little darker than the rest of Erythraeum.
Oxia Paulus,Oxus,Indus region was the darkest feature on the disc,looking bluish grey.
Morning mist at the terminator. Chryse was bright on the evening limb.
North Polar region looking bluish white,but with a brighter whiter bite on the CM,the cap showing through the hood?

We had a late clearing here but of course,the planet was getting quite low down in the west.
Seeing was average and the apparent diameter is now only 5.8" however,there were a number of interesting features on the disk:
・The SPR were bright but largely featureless.
・On the prec. side of the disk,Solis Lacus could be seen,and to the north,what I took to be Nilokeras.
・There seemed to be bright clouds on the prec. limb of the disk.
・Mare Sirenum visible on the morning side and to the south,
Phaethontis seemed to be quite bright perhaps due to white cloud activity?
・To the north of Sirenum,there seemed to be some vague shadings in Biblis Fr.
The NPC was visible although perhaps not as bright as before. A thin line just south of the cap was observed.
Seeing became too poor to continue at 2056UT.

Short cloud break gave me a chance to image Mars. Good to very good seeing.
Easily visible is Solis Lacus in the southern hemisphere and Achilles Fons in the north.
But even finer detail can be resolved,like Aurorae Sinus,Agathadaemon or Tithonius Lacus for instance.
To my own astonishment I even found the three Tharsis volcanoes Arsia,Pavonis and Ascraeus Mons easily visible in both images.
NPH gets smaller but still very bright and prominent. Lots of haze in the south around the pole region.
And haze on the p-limb with some stronger intensity over Chryse and Xanthe.
