450nm以下で大シルティスが全く写らない。もっとも、これが普通なのであるが・・・。

Marte questa sera era osservabile in discrete condizioni.
In queste zone la tempesta degli scorsi giorni sembra non essere pi〓 presente,o comunque risulta molto indebolita.
Mars this evening was observable in fair conditions. In these areas,the storm of recent days seems to no longer be present,
or in any case it is very weakened.

上空の気流は常に早く流れています。その中で少し落ち着いた時間に撮像しました。

天気予報どおりに晴れず、半ば雲の中での撮影でした。

夜中になって、急に晴れました。HELLASは、黄雲のせいか、明るく見えます。子午線湾は黄雲が薄れたのか、淡く見え
ています。ＮＯＡＣＨＩＳにも黄雲でしょうか。ＭＡＲＧＡＲＩＴＩＦＥＲ ＳＩＮ ＵＳは、まだ、淡いので、ここも黄雲がありそうです。

Much better transparency this time but seeing was quite unstable.
The martian atmosphere seems very hazy overall,but am not seeing any new dust plumes on this side.
[Robert Heffner:Osaka,Japan]
《京都府宇治市、堀内直》[T.Horiuchi: Uji- City Kyoto Japan]
Still fighting clouds,but seeing between breaks has been good. A dust veil is prominent across Noachis and Argyre;
also fainter dust partially obscures Margaritifer Sinus and brightens Chryse.
Solis Lacus is dimly seen.
[Stephen James O'Meara : Maun,Botswana]
[Du Jin Kim,South Korea]
Here is a mars report performed last 25th november under very good images with the 127 EDT refractor.
Dust veils were there as shown. From this side of the planet it seemed the dusty event intensity〓slighter than the previous night.
Here is a second report of mars performed later with the 80mmF12 scopetech refractor under fixed images almost.
The atmospheric veils are still present at the limb with conspicuous〓details.
The polar cap well seen and the polar hood proheminent at the north.
The quality of the fixed images helped a lot for this status.

Seeing 4/10 Trans 1/5
[Dmitry W. von Aichegg : Domodedovo,Moscow Russia]
Very poor conditions,but I was having withdrawal symptoms due to the recent weather,so persevered....
From the latest images,it looks like most of the dust activity has headed south-east towards Hellas,
with some residual clouds over the southern M Erythraeum regions.
[Clyde Foster:Centurion,South Africa]
≪愛知県 春日井市 伊藤了史≫[Satoshi Ito. Kasugai City,Aichi,Japan]
In reasonable conditions. A number of things of note:
・The dust seems to have largely cleared Solis Lacus. Depr. Pontica and Aonius SInus seem to be quite dark now.
・In drawing 1 there appeared to be an interesting diagonal bright zone- probably made of dust extending
from the Argyre basin into Ogygis Regio.
There was a brighter dust core over Argyre but to the north a number of details in Erythraeum could be made out.
・There seemed to be a darker region south of Argyre. Once more the SPC was small and bright.
・There seemed to be a interesting thin horizontal yellowish feature in Erythraeum ending on/near Aurora Sinus.
・Ganges contained a darker shaded region and above,Ophir and Candor were bright.
NPH seen but it did not appear to be particularly conspicuous tonight.

[Xavier Dupont,Saint-Roch France]
エリダリア付近からヘラスを経てノアキス付近まで帯状に拡がるダストが在るようにも思えますが・・・・・。
[Ki.Ozaki,Sobue Inazawa Aichi JAPAN]
≪愛知県稲沢市祖父江町 尾崎公一≫
D200mmF5.2鏡での撮影画像も添えました。コントラストがいいミラーですので薄い模様の火星撮影には適当かと思います。
D318mmニュートンは筒内気流対策ができていませんのでややコントラストは低いですが、
明日以降は鏡筒排気用冷却ファンをとりつけますので改善するかと思います。
≪滋賀県守山市 森田光治≫[Mitsuji Morita:Siga Japan]
[Pascal Lemaire : France]
Unfortunately over the central Mediterranean there is a local atmospheric cut-off low pressure that is deteriorating the visibility of the night sky during such an important period on Mars. The dust cloud seems now to have extended as far as Solis Lacus covering the entire half of this hemisphere as CM 279.8degrees.
Subtle detail can still be seen through the dust cloud,suggesting again that it is not very dense.
Getting a good focus during image acquisition is now becoming more difficult and a rather hit or miss thing.
The lack of good contrast is also leading to difficulty in proper image stacking and sharpening.
Unfortunately the weather forecast for Malta doesn't look good for the coming weeks.
[ Charles Galdies :Naxxar-Malta]
シーイングは、今日も悪い。Hellasにダストストームが入り込んで、明るく見える。Eridania方面に向かってあかるいバンドもできているのが分かる。
しかし、詳細は分からない。ダストストームは北半球の砂漠よりも明るく、目立っている。Sabaeusは黒くはっきり見えるが、Meridianiはぼんやりとしか見えない。

Still mild dust activity on this face of Mars.
[Christophe Pellier Bruz City,France]
[Niall MacNeill : Wattle Flat,NSW,Australia]
Seeing was quite bad and I had to force the processing in order to reveal some surface details.
Dust storm continues near the west terminator.
