Dust veil becomes light a little,and Hellspontus (330W,-45) has come
into view lightly. However,the whole and light continue today. The
west side of the area covered with veil is from Sinus Margaritifer
(20W,-10) to Argyre (30W,-50). NPH yellowed a little and was observed.
The cloud of Mare Acidarium (30W,+50) is observed in white. It is the
one with white clouds that Argyre (30W,-50) is bright.

火星も１５秒近くになってしまいました。光度もいくらか暗くなった
ような気がします。シーングは相変わらず悪いです。

≪群馬県佐波郡  冨田安明≫

風が強く望遠鏡が揺れていました。

≪大阪府堺市 熊森照明≫

一週間以上悪天候と悪シーイングで撮影が困難な状態が続いていました。
今夜もシーイングは悪いのですが、何とか見れる画像が撮影できたので報告します。南半球の高緯度に見られる明るい部分が気になりました。
アルギューレにしては広すぎる気がしますが、解像度が悪すぎるので定かではありません。

Hernandez (Drawing:9-inch (23-cm) F/13.5 Maksutov- Cassegrain) I made an observation of Mars on December 8-9,2005 (23:45 and 00:15 U.T.,respectively) under average to good seeing conditions (5-7/10). Detail was noted over the southern hemisphere. I welcome any comments that you may have on my observation. Date (U.T.): December 8-9,2005 Time (U.T.): 23:45 (left image,Dec. 8,2005) and 00:15 (right image,Dec. 9,2005) CM: 221.6 (left image) and 228.9 (right image) Ls: 337.4 (Late Northern Winter/Southern Summer) De -19.1,Ds -9.3,p 0.96,15.6" Instrument: 9-inch (23-cm) F/ 13.5 Maksutov-Cassegrain Magnification: 248x and 290x Filters (Wratten): 30 and 38A Seeing (1-10): 5-7,Antoniadi (I-V): III-II Transparency (1-6): 4-5 Notes: 23:45 U.T. (Left image, CM 221.6, IL/W30): The South Polar Region (SPR) was obscured by a very bright to extremely bright (8-9/10) haze (The South Polar Cap (SPC) was not visible). Mare Chronium appeared dusky to dark (3-4/10). Electris and Eridania appeared shaded to bright (6-7/10) and mottled. Mare Cimmerium appeared dark to dusky (3-4/10) with a bright (7/10) northern border and "Valhalla" visible (5/10) in sections. A thin, dusky (4/10) streak (Aethiops I ?) was visible projecting from the Northern/following border of Mare Cimmerium. Hesperia appeared shaded to bright (6-7/10) with dull (5/10) streaks across it. Mare Tyrrhenum appeared dark to dusky (3-4/10) and Syrtis Minor was dark (3/10). Zephyria, Aeolis, Aethiopis, and Aetheria appeared bright (7/10) without any other detail visible. Elysium appeared bright (7/10) on the CM with a dark to dusky (3-4/10) Phlegra to the east (preceding) and a dark to dusky (3-4/10) Hyblaeus Extension to the west (following). Extremely bright (9/10) morning limb haze (MLH), evening limb haze (ELH) and North Polar Region (NPR) were noted. 00:15 U.T. (Right image,CM 228.9,W38A): A bright to very bright (7-8/10) cloud was visible over Electris-Eridania projecting from the following limb. Mare Cimmerium,Mare Tyrrhenum,and Mare Chronium appeared dull (5/10). A very bright to extremely bright (8-9/10) cloud was visible over the Amazonis-Arcadia region towards the preceding limb. Extremely bright (9/10) MLH,ELH,SPR,and NPR were noted. Ironically the current diameter of Mars (15.6") is just smaller than the largest apparent diameter for the upcoming apparition (15.89" on December 18,2007). The best of luck and Happy Holidays to you,your family and the members of ALPO Japan. [[Carlos.E. Hernandez South Florida U.S.A ]] Ralf Vandebergh(250mm Newton:ATK-1HS)

I attach these results of observations from last night Dec 9,IRGB and blue images.
The blue image shows an obvious brightening at the east limb,already obvious during capturing
at the screen.There are nice subtle color visible over the whole disk.
