解説（安達）
低緯度地方の氷晶雲の存在が、火星のリムの近くで分かるようになってきま
した。タン・ウェイ・レオング(Tan Wei Lepong)氏の画像では南極冠のシレー
ン(MAre Sirenum;160W,-30)の経度にあたる部分が、前日に比べて淡くなって
きていることが見て取れます。ドメニコ・リチェリ(Domenico Licchelli)氏の
ブルーの画像ではサバエウス(Sinus Sabaeus;340W,-5)の南部にサバエウスと
平行に雲の出ていることが分かります。地表の色（温度）に関係があるかもし
れません。(reported by 14 observers)
August 25th, 2003
It got to understand cloud with low latitude well in the limb of Mars.
In the image of Tan Wei Leong, it finds that the longitude of Mare
Sirenum (160W,-30) of SPC became light. In the blue image of Domenico
Licchelli, light cloud can be seen in the south of Sinus Sabaeus (340W
-5). However, this may be related to the color of the Martian surface.

強風が吹き、シーイングは最悪でした。
火星像はアメーバーの如くフニャフニャで
ただ撮影したと言った感じです。

・透明度良好、気流状態最悪でした。
・南極冠の輝度はさらに弱々しくなり、
地表面の最大輝度以下になりつつあります。

夕立が北側を通過したため、幸い当地は降られませんでした。
ＰＭ８時頃から東天低く輝いて撮影を催促されているようでしたが、ＡＬＰＯに投稿する画像処理を優先させたため、撮影開始が１１時近くになってしまいました。しかし、ピントを合わせている内に見る見るモニタ上の火星が暗くなっていき殆ど確認出来なくなってしまいました。急いでＩＲカットフィルターを抜き取り撮像を開始しましたが、間もなく火星は、雲の中へ消えて行きました。
露出不足の画像をＳＴＡＣＫしてみたところＲＥＧＩＳＴＡＸの威力か大きい模様が出てきました。南極冠が縮小しているのとエリシウムの明るさが目立ちます。

撮影前に補正版をきれいにしたので、昨日よりもクリアな像
が得られた。しかし、赤いムラ状の模様が気になる。
現地時間の朝4時を過ぎるとシーイングが急に悪化したので
ここで撮影終了。(とはいっても日本では普通位ですが、)

This is the first of two attachments, as we are having a very slow ISP connection here on the mountain at this time.
This series of three Mars images of August 25 are taken about one hour apart and show the prominent Solis Lacus area, as well as a very nice fully-illuminated Olympus Mons; the peak of this volcanic cone is actually seen in the middle of the three images. Several very thin and high bluish clouds are noted, one very small one on the pr. side of the O. Mons.

Hello
Skies have finally cleared in Perth Western Australia again. We have a forecast of good weather for the next week. I have started to image Mars at the Perth Observatory with the C14 and the Meade 16inch. I have included images from both for comparison. The Meade is not mounted equatorially and suffers slightly from field rotation.

Dear mars observers
The skies cleared up at the last minute and I had to use the 10" mewlon.
Attached is the mars image from 25th August 2003. Mars has already reach the
size of 25.1", just 0.1" to go before the max size.
Seeing was unsteady for this image and I could only pick 460 shot out of
1800 manually.

Hi all,
Here are 2Mars images taken on August 25th 2003 (UT) with bad seeing(2~4/10) and fair transparency(2~3/5).

Maksutov Newtonian 150mm aperature with 3x Teleview Barlow.
Focal ratio of f/18
ToUCam Pro (1/250s shutter, 5 fps)
300 frames (2 minute .avi) processed in Registrax
"First clear night from Tokyo in quite a while. The 150mm Maksutov Newtonian needs careful collimation and quite long cool-down time, but it's optical performance is very impressive. Usually results are similar to a 200cm Schmidt Cassegrain, except that the image scale is smaller for the same focal ratio"
Kind regards
