解説（安達）/ Comment by Makoto Adachi
　ダストストームの様子は、観測条件が悪く、よくわからない。しかし、全体の広がり方を見ると、前日よりもやや広がったように見える。
Avani Soares氏はタルシス(Tharsis;80W~120W,+10)の山岳雲を記録した。一方、オリンピア山(Olympus Mons;135W,+25)には雲のない
様子も記録している。

The condition of the dust storm is poorly understood due to poor observation conditions. However, looking at the overall spread,
it appears to be slightly wider than the previous day. Mr. Avani Soares recorded a mountain cloud of Tharsis (80W ~ 120W, + 10). 
On the other hand, there is no cloud at Olympus Mons (135W, +25).

（by 3 observations; reported by Makoto Adachi)

under reasonable conditions. I suspect subtle clouds remain over the M Erythraeum and Margaritifer regions.
Some structure is seen in the SPC. Ophir/Candor remains bright.

薄曇のため、Gain を大きく上げ、露光時間も普段の数倍にしての撮影でした。

A Mars already showing enough details but still a long way away. 
What drew attention are the 3 orographic clouds over the 3 Tharsis mountains.
