解説（安達）
南半球のエッジはやや白くなり、霧の出ている様子を示している。永長氏の画
像ではミッチェル山が良く出ている。畑中氏のIR画像では、アルギ
レ(Argyre;35W,-50)付近が明るく、地上の模様も広い範囲にわたり明るく変化し
たことを示している。肉眼観測でもアルギレは形がとらえられなくなった。
Carlos.E. Hernandezのレポートでは低緯度地方に雲の帯を観測している。安達
の青色での観測も同じ様子を示しており、これからは低緯度地方の白雲にも注意
を払わねばならない。(reported by 10 observers)
Morning limb of the southern hemisphere whitens a little, and shows the
appearance from which the fog has occurred. Novs Mons is good and it is
reflected in the image of Einaga. In IR image of Hatanaka, it is shown
to be bright to be near of Argyre (35W,-50), for the pattern of the
ground to extend to the large range, and to have changed brightly. Shape
was not caught Argyre the visual observation. The belt of the cloud is
observed to the low latitude provinces in the report of Carlos.E.
Hernandez. The appearance as which the observation in blue view of Adachi
is the same is shown, and it will be necessary to take account to white
clouds in the low latitude provinces in the future. (reported by 10
observers)

コメント：少しは大気の状態が良くなると期待したが、だめだった。
南極冠の状況は２００３年の９月ごろと同じ季節に当たって
いるようで、もう少しすれば日本からもミッチェル山が見え
てくるのではと思っています。

雲が流れ、透明度が悪く、おまけにシーイングもいまいちで、曇ってしまったため途中中断もあり、条件は良くありませんでした。
ＳＰＣの様子の描出を試みましたが、元画像が良くなく、これが精一杯でした。
色調がそろえれられれば良かったのですが、なかなかうまくいきません。
それでも、ＳＰＣの自転にともなう変化の様子が、少しは出せたと思います。

 My first even partially clear dawn for 3 weeks enabled me to
capture another Mars image. Seeing was fair in Red but fair/poor in
Blue. Temp +12C. Alt 35 degrees. Cloud encroaching (as always!)from
the East.

Here are some Mars images from this morning. Poor conditions, with clouds rapidly arriving.
Note Propontis is seen near the bottom of the disk, and the small bright patch on the edge of the SPC.
14" (35cm) Celestron SCT @ F39.5.
Lumenera LU075M CCD camera.
Seeing poor (Pickering 3-4.)
Transparency initially excellent (5.5mag) clouds early.
Wind SW (5mph.) No dew.
Altitude= 34 degrees.

I made an observation of Mars on July 18, 2005 (06:50 and 07:15 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain under average (5-6/10) seeing conditions. The planet presented an impressive amount of detail although only subtending 10.4 arc-seconds. Most notable was the presence of significant cloud (haze) activity over the Electris/Eridania/Ausonia region, especially under blue (Wratten 38) light. I do not believe that dust activity was present over these regions, but instead typical atmospheric phenomena (clouds and haze). I welcome any comments on my observation.
Date (U.T.): July 18, 2005
Time (U.T.): 06:50 (left image) and 07:15 (right image)
CM: 211.9 (left image) and 218.0 (right image)
Ls 252.0, De -20.0, p 0.84, 10.4"
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 248x and 388x
Filters: Wratten 30 (magenta) and 38 (blue)
Seeing (1-10): 5-6, Antoniadi (I-V): III
Transparency (1-6): 3 (haze present)
Notes:
Left image: An observation of Mars made at 06:50 U.T. under integrated light (IL) and also using a magenta (Wratten 30) filter. The South Polar Cap (SPC) appears brilliant (10/10) surrounded by a dark (3/10) collar comprised of Mare Australe, Thyle I and II, and Mare Chronium. A very dark (2.5/10) albedo feature was noted at the approximate location of Ulyxis Fretum (190*W, -63*). The regions of Electris, Eridania, and Ausonia appeared to be partially obscured by a bright (7/10) haze (water-ice clouds/ low-lying fog?). Mare Cimmerium appeared dark to dusky (3-4/10) with it's southern border partially obscured by the bright (7/10) haze. Mare Tyrrhenum and Syrtis Minor also appeared dark to dusky (3-4/10) following the CM. Elysium was visible over the north-preceding (Np) limb and appeared to be obscured by a bright (7/10) haze. Cerberus/Pambotis Lacus/Eunostos I (4-5/10) were visible along Elysium's southern border. Zephyria, Aeolis, Aethiopis, and Aetheria appeared bright (7/10) without any detail visible within. An extremely bright (9/10) evening limb haze (ELH), North Polar haze (NPH), and morning limb haze (MLH) was noted as well.
Right image: An observation of Mars made at 07:15 U.T. using a Wratten 38 (blue) filter. A wedge-shaped bright (7/10) was noted to extend between Electris, Eridania, and Ausonia (water-ice clouds/surface fog?). A bright cloud (7/10) was noted over Elysium. The evening limb haze (ELH), North Polar haze (NPH), and morning limb haze (MLH) appeared extremely bright (9/10). The South Polar Cap (SPC) region appeared extremely bright (9/10) as well.
The best of luck in your own imaging of the red planet. The best of luck to you, your family, and the members of ALPO Japan.
