シーイングは中程度だった。Mare Sirenum はかすかにしか見えない。
おそらくダストベールで、コントラストが落ちているものと思われる。NPC周囲のバンドの幅が広く見えるようになってきた。

Visually,Mars is now very tiny. The main reason I could make this observation was because my seeing was very good.
I did not see any bright areas using the red (23A) filter,so I don't think there is much dust currently. I did see bright clouds on the p. limb in integrated light (IL) and blue light,which would indicate atmospheric clouds (water ice or CO2 ice). There was also a bright patch over Solis Lacus/Ganges on the f. limb which I found very interesting.
Mare Erythraeum to the south and Mare Acidalium to the north were both fairly dark--Meridiani not so much. The NPC was narrow and bright with a dark collar. There was also a bright spot in the south polar region.

Here is a mars report performed with the CC154mm under average good images.
Veils were noted against the color segment.
