解説（安達）/ Comment by Makoto Adachi
Mare Acidariumの北方に晴れ間ができている。Peter Edwars氏の撮影したＳＰＣの暗部は、毎回ＳＰＣに見られる「割れ目」である。
小さくなってきたＳＰＣにいつもの模様を認めた。ＳＰＣの周辺は0°付近はダークフリンジがよく分かる。
There is a fine day north of Mare Acidarium. The dark part of SPC photographed by Mr. Peter Edwars is "split" seen in SPC every time.
I recognized the usual pattern on the small SPC. Dark fringe is clearly understood around 0° around SPC.

Despite relatively poor seeing it's clear that the global contrast is still very weak.
I have included one of my image from 2003 luckily taken at same martian season and same central meridian.
The martian atmosphere was much more clear then!

透明度が悪く、風はあまり無いのにシーイングが目まぐるしく変わる状況でした。

Visually the markings other than the polar cap and dark collar are only seen with a lot of attention:
they have perhaps 25% of the normal contrast ratio.

雲間を縫ってIR850にて捕らえた火星を報告します。
[Masaaki Nagase,Kawasaki-City,Japan]
I can only submit this IR from last night as a tribute to Emil and Autostakkert.
Conditions were terrible,RGB was out of the question,
and I resorted to taking a lengthy string of IR captures in the hope that I may get lucky,
and eke something out.
Most of the data went straight to recycle bin after first process,
but this one somehow popped out.
I have noted recently the bright spot over S Meridiani and it shows quite clearly.
It has been visible in my images from 25 July.
I does not appear to have moved,so I suspect it is dust settled on the ground
and hopefully not a persistent dust cloud hanging over Opportunity rover out of spite…..
