解説（安達）/ Comment by Makoto Adachi
今日は、ダストストームの西半分の観測が集まった。Clyde Foster氏の画像はこの面の大気の情報をたくさん含んでいて素晴らしい。
7月3日に発生したエッジダストストームは1日で拡散し、すっかり見えなくなった。SPCの黄色くなった部分も淡くなった。その代り、
ダエダリア（Daedaria;W120,-30）周辺はダストが非常に濃くなり。表面模様を覆い隠している。SPCにそって、東西に深いダストが
覆っている。
赤道付近に進んでいるダストストームの先端部はリムに位置しているため、形状は分からないが、東西に延びたダストストームがはっきり
記録されている。
注意しなければいけないことは、この部分の模様のコントラストを上げると、このダストは消えてしまうことである。報告者は模様を過剰に
濃くしないようにしていただきたい。
Today the observations of the western half of the dust storm have gathered. Mr. Clyde Foster's image is great as it contains
a lot of atmospheric information on this side. The edge dust storm that occurred on July 3 spread in one day and disappeared completely.
The yellow part of the SPC also became lighter. Instead,the dust around the Daedaria (W120,-30) becomes very thick. It covers the surface pattern.
Deep dust covers the east and west along the SPC.
Although the shape of the dust storm that is proceeding near the equator is located on the limb,its shape is unknown,but the dust storm
extending east and west is clearly recorded.
The thing to be careful is that if you increase the contrast of the pattern in this part,this dust will disappear. The reporter should not
make the pattern too dark.

Not particularly good conditions this morning. Olympus Mons is at lower right.
The Tharsis Montes stretch diagonally across the centre(upper right-lower left),but are not clearly seen. S Lacus is at upper left.
Small light features are seen to the SE(upper left) of Olympus Mons,which I assume to be dust clouds.
Again,to my eye,I have the perception of dust haze across the southern albedo features.
