解説(安達)
 江口利哉氏は日本で最初のダストストームの姿をとらえることに成功した。
その画像によれば、南極冠よりの高緯度にダストストームの張り出しが見られる。
画像はカラー画像1枚だけのため、ダストストームによる雲か南極地方にできた白雲かの
区別はつかないが、形状を見る限り、ダストストームの張り出しのように見える。
また、Deucalionis Region方面に広がったダストストームの張り出しはNoachi方面にも
広がっているように見える。
 Mike Hood氏やGary Walker氏の画像を見ると、Helasを中心としたダストストームの
広がりは変化がなくなったことが分かる。その代り、Hellasを中心とした地域は
黄色くなくなり、白っぽい白雲になってきた。
 Clyde Foster氏の観測では、南極冠の北側に淡い雲が記録されている。青画像では
はっきりせず、緑画像で鮮明なことから、単なる白雲ではなく、小規模な砂嵐の可能性がある。

Mr. Eguchi caught a figure of the dust storm first in Japan. According to the image, 
an apron stage of the dust storm is seen in high latitude from SPC. 
 The distinction that is the white cloud which there was in a cloud by the dust storm 
or the south pole region is not accompanied by the image only for one piece of color image. 
I look like an apron stage of the dust storm as far as I see a shape. 
In addition, the apron stage of the dust storm which spread through the 
Deucalionis Region area seems to open in the Noachi area.
 The expanse of the dust storm around Hellas understands that a change disappeared when 
I look at the image of Mr. Mike Hood and Mr. Gary Walker. 
On the other hand, the area around Hellas was not yellow and became the whitish white cloud.
By the observation of Mr. Clyde Foster, a light cloud is recorded in the north side of SPC. 
The small sandstorm is possible not simple white cloud from a clear thing with 
a green image without becoming clear with the blue image.

Mike Hood (200mm ED refractor,355mm SC)
This image of Mars was taken with a TEC 200 mm refractor with Mars
only 24 degrees above my horizon.  It shows the progression of the dust cloud in Hellas.

Clyde Foster(355mm SCT)
Mars at 10 arc seconds with the Tharsis region central and Olympus Mons lower right of central.
Conditions made processing a bit of a challenge and the SPC is overprocessed.
During processing light cloud was noted close to the SPC. No obvious significant activity.

Gary Walker(355mm SC & 250mm APM)
Rather poor resolution due to seeing and low altitude.

Efrain Morales Rivera(300mm SC)
Under average conditions.
