解説（安達）
　瀧本氏の画像では、北半球に淡い白雲が見える。朝霧かもしれない。この
傾向は、永長氏の画像でも見られる。パ−カー氏の画像では、前日に淡くなっ
ていたオーロラ(Aurorae sinus;50W,-10)の南方はやや暗さを取り戻している。
しかし、この画像では、この部分と同じ緯度方向に棚引くような淡いダストの
バンドが写っている。画像全体から見て非常に淡いものと判断できる。ブルー
の画像からはかろうじて南極冠らしき光斑が見られる。

January 17ｔｈ, 2004.
A white cloud can be seen with the image of Takimoto faintly in the
Northern Hemisphere. This may be a mist in the morning. As for this
tendency, even the image of Einaga can be seen.
Darkness is a little taken back with the image of Parker in the south
of Aurorae sinus (50W,-10) which was faint on the previous day. But, t
he band of dust can be seen with this image in this part. It is thought
a very faint thing from the whole state of the image. As for the blue
image, SPC could be seen narrowly.

コメント：時刻が進むに連れ、シーイングが悪くなる。
Time takes for progressing and seeing becomes bad.

視直径７秒台の火星、ToUcamでこんなに写せるんですね。
シーイングが良かっただけにもう少し拡大率を上げればよかった。

It is getting pretty dificult to image, although, the seeing was below average.
So, this is the best image for that evening:
At CM 84 degrees logitude, perhaps Solis Lucas may be visible while it is merging with other albedo features.
It is hard to confirm that under the bad seeing condition.

Tiny SPC remnant glimpsed visually at 700X and suggested on the images.

Tiny SPC Remnant detected -- also glimpsed visually at 700X.
Localized cloud on SW limb -- appears to rotate with planet.
Conspicuous NP Hood and PM limb arc. Chryse bright in all filters. Aurorae Sinus very dark.
