解説（安達）
John Sussenbach氏の観測では、北半球の模様が淡く見えてきている。柚木氏
の画像では、ソリス(Solis lacus;90W,-27)に見られたダストストームの小さな
塊ははっきりしなくなったことが分かる。Damin Peach氏の画像からは、エリダ
ニア（Eridania;215W,-45）付近にダストストームのバンドのあることが読み取
れる。(reported by 8 observers)
In John Sussenbach's observation, the pattern of the Northern Hemisphere
is recorded palely. By the picture of Yunoki, it understands that the
small coar of dust storm looked at by Solis lacus (90W,-27) stopped
clarifying. It can read that dust band is near Eridania (215W,-45) in
the picture of Damin Peach. (reported by 8 observers)

Bright region near limb around Libya
obviously in NIR image,recogn in blue image.
Already some detail in Mare Cimmerium.

John Sussenbach(C11 280mm SC) |
On the first of August the seeing was here reasonable 5 to 6 /10.
The attached Mars images show Mare Cimmerium and a trace of Elysum is detectable.
Due to dust the overall contrast of the dark albedo features is low.

Still dusty on Mars,though no thick patches- perhaps things will settle out soon.
Syrtis Major seems "thin" in my image,but conditions were only fair.

シーイングが悪くピントが全く掴めない。夜明け前シーイングが一時やや改善したので撮像出来た。ソリス付近がわかる。

Images of the same area near mare Cimmerium. The RGB is still dusty bust as Don said,the IR image show the markings to be recovering at these longitudes.

Here are some images from August 1st. Excellent seeing conditions allowed some good images,and despite the hazy Martian atmosphere some finer albedo details were captured,albiet with considerably reduced contrast from normal.

David Arditti (250mm Dall-Kirkham Cassegrain) |
Slightly clearer again than the last set, but marred by a strong edge-effect. IR
here used as luminance. The limb brightness in G/Y is perhaps not entirely an
artificial effect, but indicative of the dustiness?
