解説（安達）/ Comment by Makoto Adachi
Seeing conditions improved briefly allowing for increased detail.

薄曇りの空で、最初は雲を通しての撮影でしたが、一時的に透明度は低いものの晴れたので、１セット撮影出来ました。
しかしその後は完全に曇ってしまいました。

The sky was mostly clear when I started imaging. But there were thunderclouds headed my way.
There were periods of good seeing. I had to shut down a few minutes before we had a heavy downpour.
The dust storm has engulfed a huge area around Mare Erythraeum.
Dust is still prominent on Vallis Marineris and Aurorae Sinus/Eos.
Sinus Meridiani and Sinus Sabaues can be seen on the right. The dust is headed that way.

全天を雲が覆っていましたが、やや薄くなったところで１セットだけ撮影できました。

Poors conditions of seeing 2/5 estimate,poor and variable transparency,many cirrus
Follow the evolution of the storm. It seems that the great cloud that yesterday covered Solis Lacus is dispersing.
On the other hand there is a great accumulation of dust on Foelix and Aonius Sinus. From this position,
towards the southeast it seems to continue to evolve as well,extending
[Manolo Rodriguez : El Pedroso,Seville,Spain]
We had a brief clearing here this evening,and although the jet stream was right overhead,the seeing was rather good!
The wind was a nuisance at times but overall I managed two drawings of the planet.
The first thing which caught my attention was the appearance of a bright 'dust lane' which seemed to start in Dia and pass over
(and obscuring) Coraeis Portus into Foelix and Claritas.
Aonius sinus and Solis Lacus could still be made out. Thurmasia also seemed to contain clouds/dust.
The preceding limb was yellowish from the equator up to the SPC.
On the following side,Sirenum could be seen however I had the impression that the feature was not as dark as usual.
I also had the impression that there may have been dust in Phaethontis but I am not certain of this.
The second drawing was made with a W21 (orange) filter and largely shows the same thing
but there was more structure in the brighter regions than in IL.
By 1902 the seeing became hopeless and I closed down the observatory.
[Paul G. Abel:Leicester:United Kingdom]
same area of Mars without and with the storm. Is hiding the surface of the planet.
[Joaquin Camarena:Spain]
Questa sera,poco dopo il tramonto,ho eseguito questa ripresa che mostra la tempesta in corso su Marte.
Un'elaborazione con una mia precedente immagine (ottenuta precisamente un mese fa) mostra perfettamente lo sviluppo della tempesta.
Vedremo come si svilupper〓 questo interessante fenomeno.
This evening,shortly after sunset,I took this shot showing the storm in progress on Mars.
An elaboration with a previous image of my (obtained precisely a month ago) perfectly shows the development of the storm.
We will see how this interesting phenomenon will develop.
[Fattinnanzi Cristian : Montecassiano ITALY]
ダストストームの拡散が続いているようです。IR撮影中にシーイングが悪化してしましました。
[Masaaki Nagase,Kawasaki-City,Japan]
子午線湾が復活していました。
≪大阪府堺市 熊森照明≫[Teruaki Kumamori:Ohsaka Japan]
気流が良くなく、視直径の縮小もあってか細部は写りません。
発生源の二条の所から、ARGYREの方に砂嵐が流れているのでしょうか、ARGYRE付近は昨日より明るくなっている様です。
そこから右の方にも、明るく伸びているのも、砂嵐の延長でしょうか？

Poor conditions and a race against thickening cloud. I just managed the poor IR as the clouds ended the session,
but included it for completeness anyway.
It did however allow me a first glimpse of the dust in Valles Marineris.
Incoming evening cloud is the order of the day here,but hopefully get some breaks.
[Clyde Foster:Centurion,South Africa]
11月4日以降この日迄、10日連続で晴れた。天気予報では曇るはずが、ラッキーにも晴れてくれた。しかし、透明度が悪く拡大率を落としての撮像となった。
大阪の空も火星も共にダスキーで、３色合成の際RGBの元画像のバランスが普段とは異なり、カラーバランス調整に時間を要した。アリンの爪が普段の姿に戻った。

今回は北を上にして報告します。ダストストームは太陽湖の南部を更に東に拡散しているように見える。
[青木和夫:東京都世田谷区][Kazuo Aoki:Tokyo Japan]
ダストストームは、ますます発達してきた。Noachisの南部に活動の中心部ができて、明るく見えている。まだまだ広がしそうな気配を感じる

ダストストームはさらに南北両半球へ広がっているように見えます。
≪東京都 立川市 皆川伸也≫[Nobuya Minagawa:Tokyo Japan]
318mmニュートン鏡筒内面反射防止に、全面に黒色の養生スポンジシートを張り付けた。結果は大変良好であった。
やや淡い雲越しの撮影となったが、そのおかげで眼視像は非常に安定していた。画像処理に時間がかかったので報告が遅れた。

Despite strong gusts of wind and jetstream overhead,
the attached image clearly shows the spreading dust storm on Mars.
The dust is spilling over from the Solis Lacus region on the bright limb at 10 o'clock.
I look forward to watching this storm develop and the active region rotates into view.
[Peter Edwars: West Sussex United Kingdom]
Seeing was stable: never good.
Despite that it was a joy to recognise signs of the storm at live view
and a surprise what an interesting stucture appeared in a quick image processing.
Capture time 190 sec.,exposure 11ms,gain 270. 1500 frames selected by Autostakkert 3 (just 17 aligment points),
sharpened with Registax and final processing with Photoshop.
[Michael Karrer : St.Radegund,Austria]
Very poor imaging conditions especially transparency,
but wanted to get in another observation before the jet stream strengthened again.
Have around 1TB of unprocessed data from the dust storm,including Nov 11.
Will send a composite image later.
