解説（安達）
　今日もアキダリウム(Mare Acidarium;30W,+50)付近は白雲に覆われている。
ヘラス(Hellas;290W,-50)は夕方になると、夕霧が淡くかかるようだ。アルギレ
（Argyre;30W,-50)は円形の盆地の姿が見え、晴れてきたことが分かる。Damiann
Peachはアルシア・シルバ(Arsia Silva;125W,+20)が雲に覆われていく様子を
とらえた。アルシア・シルバのすぐ北東にある小さな山にも同じ現象の起こる
様子がとらえられている。また、赤い色に見えるニクス・オリンピカも中央で
はなく、周囲が赤い色をしている様子が良くわかる。画像を見る限り、ニクス
・オリンピカも、正午を過ぎると、濃さが濃くなるのが分かる。
(reported by 9 observers)

The vicinity of Mare Acidarium (30W,+50) is covered with white clouds
today. The evening mist seems to hang lightly when Hellas   (290W:-50)
becomes an evening. It is understood that Argyre (30W,-50) is seen the
appearance of a round basin, and has cleared up. Damian Peach caught the
appearance from which Arsia Silva (125W,-50) was covered with the cloud.
The appearance in which the same phenomenon as a small mountain where
Alsia Silva exists soon in northeast happens is caught. Moreover, Nix
Olympica seen a red color understands the appearance in which the color
with a red not the center but surroundings is done well.
When Nix Olympica also passes noon as long as the image is seen, it is
understood that the density thickens. (reported by 9 observers)

が、やや青白く見える。
シーイングは少し冷え込んだため、あまり良くなかった。
今朝、１９度まで気温が下がった。

I took some blue images of Mars showing good visibility of the large Arsia orographic cloud.
This animation shows its rotation from 02:16 UTC to 03:15 UTC (one hour difference)
note its shape and especially its shadow at the lefter side.
The seeing was better in the blue light then in the other wavelengths,which is very strange.
I have noted
that already for a longer time.

Here is the complete observing set of my Aug 28 observing session.
Poor seeing during the whole night,with high clouds
but just very good seeing in the last minutes of darkness,after passing a field of clouds.
In this minutes I took these images.
The first image is one in near infra-red and shows especially Olympus Mons very well as a bulge.

The blue images below are those used for the animation of the cloud above Arsia.

The bulge of Olympus Mons is very obvious.

seeing was poor to fair and rarely the planet image appearing with some details.
I hope in best future seeing conditions..... I'm only to the beginning...
