解説（安達）
NPHはまだ明るくならない。Damian Peachの画像には面白いものが見つかっ
た。テンペ(Tempe;70W,+45)の西側に明るく小さな白い点が見つかった。見え
方から判断すると、山にかかった霜のようなものの可能性がある。アスクリス
ラクス(Ascuris lacus;85W,+53)の付近だろうと思われる。
(reported by 4 observers)
NPH has not lightened yet. The interesting one was found in the image
of Damian Peach. A bright, small, white spot was found on the west
side of Tempe. Judging from how to see it, there is a possibility of
the one like the frost that hangs to the mountain. It seems near
Ascuris lacus (85W,+53) it might. (reported by 4 observers)

寒気の流入が激しく、１８時を過ぎるまではまともな像は得られませんでした。

コメント：寒い・・・
体調を崩して、観測できませんでした。
それにしてもこんなに寒い１２月は初めてです。
この後、雲って観測を中止。その後、雪となった。

I made an observation of Mars on December 17, 2005 (01:00 U.T.) under average seeing conditions (5-6/10), but had to peek through "holes" in the clouds passing overhead. The weather did not allow me to make a blue light (W38A) observation. I welcome any comments that you may have on my observation.
Date (U.T.): December 17, 2005
Time (U.T.): 01:00
CM 166.5
Ls: 341.7 (Late Northern Winter/Southern Summer)
De: 19.2, Ds: -7.6, p 0.94. 14.3"
Instrument: 10-inch (25-cm) F/9 Newtonian (Palermiti Observatory)
Magnification: 320x
Filters: Klee OPS Barlow (employs a filter layer within the lens)
S (1-10): 5-6, Antoniadi (I-V): III
Transparency (1-6): 1 (visible through holes in the clouds)
Notes:
01:00 U.T. (CM 166.5): The South Polar Cap (SPC) was not visible at this time (SPR haze?). Mare Chronium appeared dusky (4/10) on the CM. Mare Sirenum appeared dark to dusky (3-4/10) preceding the CM. Mare Cimmerium appeared dark to dusky (3-4/10) following the CM. Electris and Eridania appeared bright (7/10) with thin, dull (5/10) streaks across projecting from Mare Sirenum and Mare Cimmerium. Memnonia, Zephyria, Aeolis, and Aethiopis appeared bright (7/10). The Propontis Complex appeared dusky (4/10) adjacent to the extremely bright (9/10) North Polar Region (Hood) preceding the CM. Phlegra appeared dark to dusky (3-4/10) following the CM towards the North-following limb. Extremely bright (9/10) morning limb haze (MLH), evening limb haze (ELH), and South Polar Region (SPR) were noted as well.
The best of luck to you, your family and the member of ALPO Japan. Thank you for your latest images of Mars, Saturn, and Venus.

Here are some images from Dec 17th. Mars is shrinking fast. A misty cloud over Sinus Meridiani, and also the south polar cap looks rather misty. Also a weak morning cloud over. Daedelia.
