解説（安達）/ Comment by Makoto Adachi
1)地上観測を基にした解説（Comments based on images shot on the earth）
Hellasは明るくなく、南部がSPCによって少し狭められた姿をしている。Syrtis Majorの赤道部はターミネーターにかけて白雲が見えている。
北極付近はMare Acidariumの方向にダストベールがあるようで、黄色っぽい姿を見せている。
Hellas is not bright,and the southern part is somewhat narrowed by SPC. In the equator part of Syrtis Major,white clouds are visible through
the terminator. There seems to be a dust veil in the direction of Mare Acidarium near the Arctic,showing a yellowish figure.

2)MRO画像を基にした解説（Comment based on the image from MRO）
Eden北部の注目されるダストストーム以外にも、西経150度にあるPropontis IIの暗斑の北側に小さく目立ったダストストームが見ら
れる。ここにはなぜか、しばしば同じものが見られ、1〜2日で拡散してしまう。今回のものも翌日には西に流され、見えなくなる。
Eden北部の大ダストストームは西経0度付近で馬蹄状の姿になっている。西南西の方向に風に流されている姿がはっきり見られる。
この位置はMare Acidariumの北東方向にある帯状の地表の模様と傾きが一致している。地形的にも、ダストストームの進行にかか
わりがあるように見える。
In addition to the notable dust storm in the northern part of Eden, small dust storms are seen on the north side of the dark spot of
Propontis II at 150 degrees west. Here, for some reason, the same thing is seen often and it diffuses in one or two days. The thing of
this time is also drained to the west on the next day, it disappears.
The large dust storm in the northern part of Eden has a horseshoe shape near 0 degrees west. It is clearly seen that the wind
is being swept in the direction of the west-southwest. This position is in agreement with the inclination of the belt-shaped ground
pattern in the northeast direction of Mare Acidarium. Even topographically, it seems to be involved in the progress of the dust storm.
