解説（安達）/ Comment by Makoto Adachi
今日も南極と北極の白雲が顕著に観測されている。南極冠の上にできる背の低いプロジェクションは今日も見られた。（Clyde Foster氏・
Christophe Pellier氏・阿久津富夫氏）全球で2か所みられる。
Clyde Foster氏の画像では南極冠が半分だけ見えている。Hellespontusの冷気の吹き出しによる影響を受けている。このため、Hellasの
ダストストームの西の輪郭が見えている。ただし、これは堆積したダストストームの輪郭と同じ可能性がある。IR画像では下の模様の様子が
わかるが赤画像では全体がベールに覆われている様子をよく示している。
Christophe Pellier氏の画像では北半球の
ダストストームがやや淡いため、Mare Acidariumが広く暗く見えている。
Blue clouds of Antarctica and Arctic are also observed remarkably today. Tall projections that can be seen on the SPC were also seen
today. (Mr. Clyde Foster,Mr. Christophe Pellier,Mr. Takao Akutsu) There are two places in the global.
In the image of Mr. Clyde Foster,only half of the SPC is visible. Hellespontus' cold air blowing out is affected. For this reason,
the outline of the west of Hellas' dust storm is visible. However,this has the same possibility as the contour of the deposited dust storm.
The IR image shows the state of the lower pattern,but in the red image the whole is well covered with veil. .
In the image of Christophe Pellier,the dust storm in the northern hemisphere is a little pale,so Mare Acidarium appears wide and dark.

-------------------------------------------------------------------------------------
CM 10,so Sinus Meridiani and Margaritifer still heavily obscured. Better seeing is projected by Meteoblue in coming days,but we shall see.
Mars midnight session last night,with what is meant to be Syrtis Major central,and Hellas basin upper central.
The IR definitely seems to cut through the dust,at least to some extent.
The SPC is heavily affected by the dust,and there is some finer dust detail on the bright section of the cap.

Images were poor but a relative hole into seeing helped to produce the present report.
Still very low contrasts on features assimilated to ghost features
but with a relative contour which correspond to the known formations.
Syrtis Major is not fully occulted,general contrasts can be stated less than 5% except
on the dark border of the polar cap more vivid.
[Stanislas Maksymowicz Ecquevilly,France]
Still very active dust clouds at these longitudes.
[Christophe Pellier Bruz City,France]
Seeing was better on the 28th.
I took a very similar longitude on the 29th (so that was a bit of a waste of time).
Clearly Sinus Meridiani is now visible.
It’s true however that IR images like this don’t represent the visual view accurately.
I couldn’t see Sinus M visually.
The dust scatters the long wavelength of the IR less,
and then there’s some sharpening applied; how much,
and so how visible to make the contrasts,is a matter of judgement.
But I try to maintain a consistent process from night to night.

Very poor conditions so took a quick image set for the record.
This shows the Chryse hemisphere of the planet - not that you would know it given everything is covered.
Dust across the SPC also.
