I hope that you,your family,and your fellow ALPO Japan members have been doing well. The images and observations of Mars posted on the ALPO Japan web site are very impressive for the apparent diameter of Mars.
I was treated to an exceptional view of the planet Mars on January 18,2010 (06:15-07:00 U.T.). I observed fine detail over the Martian surface (and atmosphere) extending between Amazonis on the preceding limb and Syrtis Major on the following limb. During moments of steady seeing the Hybaleus Extension-Aetheria region of Mars reminded me of the observation of the same region made in 1909 by the famous Greco-French astronomer Eugene M. Antoniadi (1870-1944) at which time he described the region as composed of dark knots and streaks. The region between Trivium Charontis and the Propontis Complex was also complex.
Date (U.T.) January 18,2010
Time (U.T.): 06:15-07:00
CM (Degrees West): 234.4-245.3
Ls 039.5* (Mid-Northern Spring/Southern Autumn)
De: 16.1*,Ds 15.4*,Phase 99%,13.9 arc-seconds
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 295x and 443x
Filters (Wratten): 30 (Magenta) and 80A (Blue)
Seeing (1-10): 8,Antoniadi (I-V) II
Transparency (1-6): 5
Notes:
06:15 U.T. (CM 234.4*W, Wratten 30 (Magenta)): The North Polar Cap (NPC) was brilliant (10/10) with dusky to dull (4-5/10) streaks noted within it. I believe I noted the initial separation of the NPC remnant Lemuria (~205*W) along the southern border of the North Polar Cap. The NPC dark to dusky (3-4/10) collar was composed of Lemuria and Utopia/Casius. The Hybaleus Extension was visible on the central meridian (CM) and appeared to be composed of dark to dusky (3-4/10) streaks and condensations (knots). Elysium was visible preceding the CM with a very bright (8/10) cloud over the northeast (north-preceding) sector of Elysium. Trivium Charontis/Phlegra/Azania appeared dark to dusky (3-4/10) and mottled over the preceding border of Elysium. Nodus Alcyonius was visible following the CM as an elliptical ("teardrop") shaped albedo feature. Mare Cimmerium was visible preceding the CM and appeared dark to dusky (3-4/10). Hesperia was visible as a diagonal, bright (7/10) following the CM. Mare Tyrrhenum (3/-510) and Syrtis Minor (3/10) were visible following the CM. Syrtis Major was visible as thin, dark to dull (3-5/10) projection ("finger") over the following (morning) limb partially obscured by very bright to extremely bright (8-9/10) haze. The preceding (evening)/southern/following (morning) limbs appeared very to extremely bright (8-9/10).
07:00 U.T. (CM 245.3*W,Wratten 80A): The North Polar Cap (NPC) appeared brilliant (10/10). A very bright (8/10) cloud was visible over the northeast (N-p) sector of Elysium whereas the rest of it appeared bright (7/10). A bright to very bright (7-8/10) haze was visibly extending from the morning limb haze (8-9/10) over Aetheria. The preceding (evening)/southern/following (morning) limbs appeared very to extremely bright (8-9/10).
The best of luck in your own imaging/observations of Mars.

コメント：昨晩よりもシーイングは良くなかったのですが、画像処理は楽でした。
しかし、火星の色合いはむずかしいです。機械的な処理で一定にした
いのですが・・・
極付近の様子に少し変化があるような気がします。

Very good seeing,especially in the blue channel with only little disturbance at the discs rim. Red channel much more unstable.
