解説（安達）/ Comment by Makoto Adachi
南極冠のターミネーター付近に背の高いプロジェクションが出現した。次の観測者の画像にその様子が記録された。（Clyde Foster・
Bruce Macdonald）そのほかの観測者の画像にもかすかに見られるものがあるが、はっきりしない。これは南極冠のエッジよりも少し内部
に入り込んだ位置にある。カラー画像では白雲かダストが巻き上げられたものかの判断はできない。ダストストームが南極冠の上に入り
込んで起こった現象であることは確かだ。
西経０°から100°付近の南極冠はダストストームの侵入を受け、黄色くかすんでいる。
Christophe Pellier氏の画像では南極付近や北極
付近の白雲が見事にとらえられている。
Bruce Macdonald氏の画像は注目される。ダストストームの濃い部分が南北の縦じまになって記録されている。おそらく南極冠の部分
のように高度の高いところにまで発達しているのだろう。また、この画像はダストストームの広がりが非常にによくわかるものだ。畑中氏
の画像は興味深い。RGBだとSyrtis Majorはほとんど写らないが、IRだと非常によく見え、RGBだとダストストームの影響を大きく
受けることがよくわかる。このRGB画像は肉眼観測で見た火星面に少しコントラストを付けたような姿に記録されている。今日は
Daedaria付近に晴れ間が見られた。
Christopher Go氏の画像ではダストストームが南極冠に侵入して背の高い白雲になっている様子を記録している。本来の南極冠の緯度
よりも北側に広がった姿をしている。この様子は、Milika-NicholasのIR画像でも記録されている。
Tall projections appeared near the terminator of the SPC. This state was recorded in the image of the next observer. (Mr. Clyde Foster,・
Mr. Bruce Macdonald) There are some faint images of other observers,but it is not clear. It is in a position slightly inside the edge of
the SPC. In color images it can not be judged whether white clouds or dust are rolled up. It is certain that it is a phenomenon caused
by the dust storm entering the SPC.
The SPC around 0 ° to 100 ° West west is invaded by dust storms and is hazy yellow.
In the image of Mr. Christophe Pellier,the clouds
in the vicinity of the Antarctic and the North Pole are captured brilliantly.
The SPC around 0 ° to 100 ° West west is invaded by dust storms and is hazy yellow.
In the image of Mr. Christophe Pellier,the clouds
in the vicinity of the Antarctic and the North Pole are captured brilliantly. Mr. Bruce Macdonald's image is drawing attention.
The thick part of the dust storm is recorded in the north-south vertical strip. Perhaps it is developing to a high altitude like the SPC.
Also,this image shows the extent of the dust storm very well. Mr. Hatanaka's image is interesting. In RGB,Syrtis Major hardly appears,
but it looks very good if it is IR,and it is obvious that RGB has big influence of dust storm. This RGB image is recorded in such a form as
giving a slight contrast to the Mars surface as seen by macroscopic observation. A sunny day was seen near Daedaria today.
Christopher Go 's image records the appearance of dust storm entering the SPC and becoming a tall white cloud. It spreads to
the north side than the latitude of the original SPC. This situation is also recorded in IR image of Mr. Milika-Nicholas.

Poor conditions. This face of Mars is almost unrecognisable with very little detail visible.
[Clyde Foster:Centurion,South Africa]
Follow-up of the storm from this morning ! I think the storm is only reaching its paroxysm now.
And that it could be even denser et wide than in 2001.
[Christophe Pellier Bruz City,France]
Left side of planet under sand storm,
not visible Arabia Area,Sinus Sabaeus.
Mare Acidalium still visible
[Guilherme Grassmann,Americana-San Paulo,Brasil]
(Bruce Macdonald : Punta Gorda,Florida USA)
Some familiar shapes visible through all the dust
[Simon Kidd: Welwyn Herts,United Kingdom]
It looks here like there is a general semi-opque obscuration,but distinct thicker clouds of dust seem to be visible on the terminator.
N and S up images given.
[David Arditti: Edgware Middlesex HA8 5LW: United Kingdom]
22時ころ、雨が降っていたので、無理と思っていたが、2時半頃目が覚めて窓から見ると晴れているので撮影した。
雨上がりだったが、案外揺れは少なかった。 しかし、模様の濃さは、昨日より薄かった。
今日もダストストームの中に白い雲（水蒸気？）が、見える。形は変化しているが。可視像、近赤外像、ブルー像を比べるとおもしろい。
≪三重県熊野市 畑中明利≫[Akitoshi Hatanaka:Kumano Mie Japan]
Excellent conditions today.
Unfortunately,Mars still hides its prominent features with a global dust storm!
Mare Cimmerium is suppose to be at the CM but one could hardly see it!
Sinus Gomer is very faint but is slowly peeking out of the dust.
There is a hint of Elysium in the north.
[Christopher Go : Cebu Philippines]
[Szabolcs Nagy: London United Kingdom]
Poor seeing. The planet is unrecognisable. I include inset a view of how it should look!
[Damian Peach: Loudwater,Buckinghamshire,United Kingdom]
Under average conditions,we can see again clouds on Northern polar area,
and close to the Southern polar area on the limb. South polar Cap show some details.
[Marc Delcroix Tournefeuille,France]
Under dense Saharra dust aerosols.
[Efrain Morales Rivera Aguadilla:Puerto Rico]
Only an iR610nm as the seeing was fairly pedestrian this night.
[Milika-Nicholas:Adelaide,South Australia]
