解説（安達）
 ブルークリアリングは、柚木氏の画像によればしだいに収束しつつあるよう
に見える。ブルー画像ではあちこちにむらがある。明るくなっている部分が、
果たして水蒸気によるものか、あるいはブルークリアリングによってできた明
部かの判断はつかない。画像からはシルチス・マイナー(Syrtis Minor;260W,0)
の位置が、はっきりと確認できる。
 NPHは明るくよく目だっている。一方、南極付近はヘイジーでコントラスト
の低い状態が、今日も続いている。畑中氏のIRの画像は、クロニウム(Mare
Chronium;200W,-57)がはっきりと出ている。このことからこの周辺はダストの
ベールが覆っていると判断できる。Carlos.E. Hernandezの肉眼観測でも南極
を取り巻く地域の色が違っていることが記録されている。Nicolas BiverはSPC
の周囲が黄色になっている様子を記録した。畑中氏は、シルチス(Syrtis
major;290W,+10)の真上に朝霧を記録しているが、それよりも早い時刻の永長
氏の画像では、畑中氏よりも南方に朝霧を記録している。短時間の間に朝霧の
目立つ地域が大きく移動している様子が記録されている。ソリス・ラクス
(Solis Lacus;90W,-25)付近はD.C.Parkerが観測した。これらの画像にはSPCが
鮮明に記録された。南極周辺のダストはやや収まる傾向にあるようだ。Damian
Peachの画像は、細部まではっきりと記録できている。それによれば、アルギ
レ(Argyre;30W,-50)の上に白雲が出ていることが分かる。また、ダストストー
ムによって明るくなったアルギレが、ダストベールがとれることによって暗く
なったことが判明した。(reported by 15 observers)

It seems to be settling blue clearing gradually according to the image
of Yunoki. There is irregularity in brightness here and there in blue
image. The judgment of the discernment part that can have been done by
due to steam the part that has lightened or blue clearing doesn't
attach. The position of Syrtis Minor (260W,0) can be clearly confirmed
from the image.
NPH conspicuously bright. On the other hand,the state with low
contrast leads to the vicinity of the South Pole by heyzy today. In
image of IR of Hatanaka,Mare Chronium (200W,-57) is clearly seen. It
can be judged that this circumference is covered from this with dust
veil. Visual observation of Carlos.E. Hernandez is recorded the color
in the region where the South Pole is surrounded different. Nicolas
Biver recorded the appearance where surroundings of SPC are yellows.
The morning mist is recorded from Hatanaka to the south in image of
Einaga that is earlier than it though Hatanaka records the morning
mist right above Syrtis major (290W,-50). The appearance where the
region where the morning mist is seen in a short time moves greatly
is recorded. D.C.Parker observed the vicinity of Solis Lacus (90W,-25).
SPC was clearly recorded in these images. Dust around the South Pole
seems to tend to install a little. The image of Damian Peach can
clearly record even the detail. It is understood white clouds are
generated on Argyre (30W,-50) according to it. Moreover,it turned
out that Argyre that lightened by dust storm had darkened by dust
veil's clearing up.

撮影開始後すぐに雲が広がり
まともなのは、この1枚だけでした。
シーイングもたいへん悪い。

薄雲があったので拡大率を下げました。
もう少しいいシーイングにならないかなぁ！

I made an observation of Mars on November 17,2005 (05:00 and 05:45 U.T.) under average to good seeing conditions
(5-7/10). Much detail was noted over the southern hemisphere from Solis Lacus to Mare Cimmerium.
A bright (7/10) streak was noted along the length of Mars Sirenum (cloud vs. dust?).
I welcome any comments that you may have on my observation.

Notes:
05:00 U.T. (Left image,CM 135.8,IL/W30): The South Polar Cap (SPC) was brilliant and very small
(more readily noticeable during moments of steady seeing). Mare Austale was dusky to dull (4-5/10) and mottled.
Solis Lacus appeared dark to dusky (3-4/10) over the south-preceding limb.
Ambrosia (5/10) and Bathys (5/10) were noted to project from the southern border of Solis Lacus.
Geryon (5/10) and Calydon (5/10) were noted to project from it's northern border.
Aonius Sinus appeared dusky (4/10) with Phasis (5/10) projecting from it's northern border.
Daedalia,Phaethontis,and Electris appeared bright (7/10).
Mare Sirenum appeared dark to dusky (3-4/10) and mottled following the CM (Caralis Fons (4/10) was noted along it's following-southern
border). A bright (7/10) streak was noted within Mare Sirenum along it's east-west length (possibly a cloud or dust?).
Araxes was noted as a dull (5/10),diffuse projection over the preceding end of Mare Sirenum.
Mare Cimmerium was diffusely visible within the extremely bright (9/10) morning limb haze (MLH).
Memnonia and Zephyria appeared bright to very bright (7-8/10) north of Mare Sirenum. Tharsis and Amazonis appeared bright (7/10).
Tempe and Arcadia appeared dull to shaded (5-6/10).
Olympus Mons appeared as a bright (7/10) circular albedo feature over Tharsis preceding the CM.
An extremely bright (9/10) evening limb haze (ELH) and North Polar Haze (NPH) were noted as well.

05:45 U.T. (Right image,CM 146.8,W38A): Solis Lacus,Mare Sirenum and Mare Cimmerium appeared dull (5/10).
A very bright to extremely bright (8-9/10) cloud was noted to project from the preceding limb over Tharsis.
Bright to very bright (7-8/10) clouds were noted over Memnonia and Zephyria.
Extremely bright (9/10) evening limb haze (LH),morning limb haze (MLH),and North Polar Haze (NPH) were noted as well.
A very bright (8/10) projection (cloud) from the NPH was noted over Tempe-Arcadia.

Here are my best efforts from last night - frosty and fairly good seeing. My
first night using R(G)B allowing longer runs on R and B.

A set of Mars images taken last night from the continuing frozen wastes
of Suffolk,UK,is attached. This is my 36th night of imaging Mars this
apparition.

Mare Erythraeum is almost on the Meridian.

Seeing was poor visually,but I'm quite pleased with the result.

Temp + 1C but no dew in the dry,cold air.

Poor seeing. Lots of clouds over Tharsis but Olympus Mons clear.
