解説(安達)
 明け方のエッジでは、アキダリウム(Mare Acidarium;30W,+50)付近の白雲と、
南半球低緯度の白雲が目立っている。ここしばらくは、同じ傾向が続いている。
瀧本氏の画像では、北半球が南半球とくらべると、かすかに赤っぽく見えてい
る。火星が地平線から昇ってくる時は、この傾向が強くなる。根市氏や小石川
氏の画像では、アキダリウム(Mare Acidarium;30W,+50)付近の白雲の様子が非
常に良く分かる。キンメリウム側では、目立った変化は見られないが、こちら
側もNPHがはっきりしている。(reported by 15 observers)

In morning edge, white clouds in the vicinity of Mare Acidarium (30W,
+50) and white clouds of low latitude of the southern hemisphere are
remarkable. Recently, the same tendency continues. In the image of
Takimoto, the northern hemisphere looks faint red compared with the
southern hemisphere. This tendency strengthens when Mars rises from
the horizon. In the image of Neichi and Koishikawa, the appearance of
white clouds in the vicinity of Mare Acidarium is understood very well.
A remarkable change is not seen on the Mare Cimmerium (210W,-20) side,
and NPH is clear hither.

コメント:火星が東の空に上がって、さあ観測を始めた途端、
雲が北の空以外は覆ってしまい1枚のみの観測と
なった。今年の天気は雲り空が多いが、雨量は少ない。
視直径も17秒台となって、小口径でも観測可能では
あるが、シーイングが悪い状況となっている。
火星面は、大まかな模様しか見えない。

天気予報に反して雲が切れない。シーイングは良いのでかなり様子を見たのだが、いっこうに雲が切れず、全面を雲が覆い始めた。雲を透しての撮像となり、R系の画像しか得ることは出来なかった。

コメント:SonyHC1の撮影のコツが分かってきたので、今回も露出を
1/125秒に設定してシーイングの悪い分を補っています。ゲインを
最大の18dbにすると1/250秒でも撮影できますが、さすがに画面が
ザラザラになってしまうので、1段落とした15dbで1/180秒にするか、
2段落とした12dbで今回のような1/125秒位で撮影するのが良さそう
です。ToUcamの感覚で1/30秒に設定すると、画面は大変滑らかで過剰
クオリティーになりますが、鳥取の悪シーイングでは像はボケボケに
なってしまい、全く使い物になりません。2枚目や3枚目と同じ条件
であっても、おそらくは1枚目のようなボケボケの画像になったで
あろうと思われます。
やはりこのカメラの高速シャッターで惑星に対応できる能力はありが
たいです。

28日から29日にかけて、10日ぶりに観測できました。
気流透明度ともに良く、今までにないくらいの良画像を取得できました。
特に、北極付近の青白い雲が見事ですね。
また、火星情報での中規模の砂嵐の前兆は、ないように見えますが。

シーイングが悪く、観測意欲がわいてきません。なかなか粘れなくなってきました。
気力、体力の衰えに、我ながら情けないことになってきたものだとややがっくりきています。
・クリセ平原あたりの輝きがとても強いです。

Here are some images from this morning. Poor seeing with the jetstream parked overhead.
In Blue note the Arsia Mons orogprahic cloud is present on the evening terminator. Also a weak cloud just south of Propontis. A bright morning mist covers Ausonia across Mare Cimmerium. Also a dense patch of mist toward the SPC over Mare Chronium. The NPH is thick with a dark band on its southern boundary.
14" (35cm) Celestron SCT @ f/39.5.

Seeing poor occ fair (Pickering 2-5.)
Transparency variable with frequent low clouds (cloud - 6.0mag.)
No wind. Heavy dew.

I made observations of Mars on September 28, 2005 (06:30 U.T. (IL/W30) and 06:50 U.T. (W38)) under average seeing conditions (5-6/10). Brief moments of steady seeing (7/10) allowed me to note much detail over the Martian disk, especially over the southern hemisphere. I welcome any comments that you may have on my observations.

Notes:
06:30 U.T. (Left image, IL/W30): The South Polar Cap (SPC) appeared very small but brilliant (10/10) and surrounded by a dark (3/10) collar (Mare Australe). Mare Cimmerium was prominent (3-4/10) and mottled preceding the CM with Tritonis Sinus on the CM itself. A section of "Valhalla" was visible (5/10) to the north of Mare Cimmerium towards the preceding limb. Scamander was visible along the southern border of Mare Cimmerium (it's base (Scamandri Sinus) was darker (3/10) compared to the rest of the feature (4-5/10)). Electris, Eridania, and Ausonia appeared shaded to bright (6-7/10) and finely mottled. Mare Chronium appeared dusky (4/10) along the CM towards the south. Hesperia appeared as a bright to very bright (7-8/10) angled wedge on the CM between Mare Cimmerium and Mare Tyrrhenum (3-4/10). Syrtis Minor was visible as a dark (3/10) wedge following the CM. Mare Hadriacum was visible as a dusky to dark (3-4/10) eastern (preceding) border of a very bright to brilliant (8-9/10) Hellas. Iapygia Viridis was visible (4/10) adjacent to an extremely bright (9/10) morning limb haze (MLH). Syrtis Major appeared as a dark (3/10) wedge adjacent to the MLH. Moeris Lacus (4-5/10) was visible projecting from the preceding (eastern) border of Syrtis Major. Libya appeared very bright (8/10) possibly due to clouds or haze. Aeolis, Aethiopis, and Aetheria appeared bright (7/10). Elysium was very bright to extremely bright (8-9/10) along the north-preceding limb. Pambotis Lacus (3/10), Eunostos (4/10), and the Hyblaeus Extension (3-4/10) were visible along the following border of Elysium. Nodus Alcyonius was visible as a dark (3/10) oval following the CM. Utopia was partially visible (4/10) south an extremely bright (9/10) North Polar Hood (NPH). An extremely bright (9/10) evening limb haze (ELH) was visible as well.

06:50 U.T. (Right image, Wratten 38): The South Polar Cap (SPC) appeared brilliant (10/10). Mare Cimmerium and Mare Tyrrhenum were visibly dull (5/10) with little other detail towards the center of the disk. Syrtis Major was  visible as a dull (5/10) projection towards the following limb. Libya appeared very bright (8/10). Hesperia appeared as a thin, bright (7/10) wedge just preceding the CM. Hellas appeared very bright to extremely bright (8-9/10) with very bright (8/10) projections extending from it's preceding border over Ausonia. Extremely bright (9/10) morning and evening limb hazes (MLH and ELH) were visible. the North Polar Hood (NPH) appeared extremely bright (9/10) as well.
