≪神奈川県相模原市 佐藤康明≫
雲のある晴れで、Ｂ画像の5回目は雲が来て、撮れませんでした。ヘラスから左の方まで、ダストストームが広がっているのでしょうか? Ｂ画像では大シルチスに雲があるようにも見えます。

時間が経つとともにシーイングがどんどん悪化したため、途中で断念しました。

上空を薄雲やうろこ雲が高速で移動していましたが、思ったよりも模様が見えました。

シーイングはダメでした。Gain を上げても他の５倍露光時間のかかるBE410フィルターでの撮影は、もう無理な感じです。
≪大阪府 枚方市 井上 修≫[Osamu Inoue. Hirakata-shi,Osaka,Japan]
Bads conditions of seeing 2.5/5 and transparency〓2/5 estimate.
After a few days of rain,some gaps〓between highs cirrus clouds finally opened at the end of the day.
Although the image is not very good,the decreasing evolution of the dust storm in this area seems to remain without much changes.
The Hellespontus-Noachis area is still covered. Already in Argyre it is less thick.
The scattered dust seems to reach Mare Australe and the south pole itself appears dim in its brightness.

ほぼ10日ぶりに晴れました。ヘラス辺りもダストの影響は見られません。
<<北海道札幌市 宮原正育>>[Miyahara Masayasu. Sapporo,Hokkaido,Japan]
この時間だけ少し気流が改善しました。

≪宮城県大崎市 佐々木一男≫
ヘラス周辺から大シルチス南部周辺にかけてダストが広がっているようです。
厚い雲が通過する中で薄くなったところを見計らって撮りました。シーイングは極悪ではないものの透明度は最低でした。

The albedo on Mars hows two interesting deviations:
(1) the dense streak over Argyre extending from Noachis is evident in the RGB-IR image.
This darkness might be due to the presence of dust still prevalent in that area (See Manolo Rodriguez observation of 2020/11/30 19:33UT).
(2) An extension of Niliacus Lacus towards Oxia Palus is also evident. This feature is not the first time that I have recorded it.
Most of Mare Erythraeum is dark with no albedo variations. This could be due to the dust prevalent over this area,
which unfortunately is not so evident in my RGB-IR image due to non-optimal weather conditions.
Chyse seems to be covered by some limb clouds. The south pole is now very much reduced in size.
[ Charles Galdies :Naxxar-Malta]
I managed to make a drawing of Mars although I had to wait until rain clouds cleared,
and I only had half an hour before more cloud arrived from the North.
The seeing was average,but with a few brief better moments.
〓
No morning mist seen. The Evening Limb was yellow with dust,but not especially bright now.
Moab was a little brighter on the Evening Limb. Hellas appeared brighter still,and yellow.
Hellespontus was well seen and appeared free from dust.
Depressiones Hellesponticae appeared quite dark and I had a few glimpses of a parallel dark streak running from there into Western Hellas.
Noachis appeared dusky,Argyre bright and clear.
〓
SPC appeared uniform and bright white.
NPH appeared normal and bright white. Indus and Oxia Paulus well seen in the North.
Margaritifer Sinus,Aurorae Sinus,Mare Erythraeum,Pandorae Fretum,Deucalionis Regio,Sinus Sabaeus,and Sinus Meridiani all appeared normal.
[Chris Nuttall : York,UK]
Very difficult seeing,most of the time blurring images,just short moments of less bad seeing.
I could process just one film of 18. Hints of the storm still dedectable.
Cloudy weather with snow as forcast - maybe my last attempt to image the planet.
[Michael Karrer : St.Radegund,Austria]
よく晴れたが、シーイングは極めて悪かった。 ダストストームは、かなり衰退して、元の模様が見えている。
ダストに覆われて明らかに形の見えないというところはなく、コントラストは低いもののすべての模様は見えているようだ。
ただ、シーイングが悪く、詳細不明。

Fairly good seeing conditions here on the 30th,
the attached is the result of 2 x 4,000 frames de rotated in Winjupos (5 mins),
each AVI just 2.5 minutes in length (about 20,000 frames each).
