も明るい白雲に覆われている。また、アキダリウム(MareAcidarium;30W,+50)
付近には濃い白雲が見えている。ヘラス(Hellas;290W,-50)も白雲に覆われて
いる。(reported by 16 observers)
A light cloud has extended to the vicinity of Tharsis (95W,+10).
Moreover, it is covered with white clouds with bright Arctic area.
Moreover, thick white clouds are seen in the vicinity of Mare
Acidarium(30W,+50). Hellas (290W,-50) is covered with white clouds.

今朝は、この夏初めての透明度の良い快晴の天気でした。
FujiFilmのBPB45フィルタ使用の画像を1/5secで撮影してみました。
昨日より画質は向上しますが、地表の模様が写っており、別のフィルタを探します。

コメント：
オリンポス山、アルシア、パボニス、アスクレウス３山が
辛うじて写っている。（眼視では、確認出来ず。）
南極冠は、ひょうたん型に見える。
この日も、27時過ぎ（JST)から低層の霧のような雲が湧き、
透明度が一気に悪くなった。今年の夏、特有に感じる。

懲りずに、擬似３Dのアニメーションを
作ってみました。（学術的では無いですが）
画像の色、濃度が均一でないと
パッシング現象が現れてしまいますね…

<眼視の印象>
火星のリムが白く輝いて見えた。
北極の周りが白く見えた。
TeleVueのMarsBフィルタを使うと,ソリスが濃く見えた。
<Impression-visual observation->
It seemed that the rim of Mars shone in white, and looked white surroundings of the North Pole. When the NPS filter of SIRIUS OPTICS was used, it becomes easy to see the albedo features. When the MarsB filter of TeleVue was used, S0LIS PLANUM looked thick.

撮影方向に薄雲がかかり透明度が良くない。北極地方に雲がＢ画像でわかる。

コメント：撮影開始直後は比較的シーイングに恵まれたが、
その後、雲が広がり撮影が中断した。雲が切れ
た後はシーイングが悪くなってしまった。
ソリスの形は、池村さんのシミュレーションと
良く一致しています。

Seeing began very poor, but improved enough to get a few images later.
I note a large increase in the brightness and scope of the NPH in the past 48 hours.

I send you a Mars image from this morning - 2005/08/18 19:28 UT
Comments: Solis Lacus can be seen in detail, the volcanoes Tharsis and Mt.
Olympus Mons can also be seen. Seeing conditions were pretty rough during
the capture, though imaged @ 74fps using the LU075.

I think this is a good comparison between the Canon and ToUcam. The biggest advantage the ToUcam has is that I can remove the IR blocking filter and use an IR pass filter.
Attached is a short animation of Mars rotating between 7:40 and 8:50 UT, 8-18.
Clouds during some of the exposures forced me to abandon the color.

The fifth consecutive clear dawn in Suffolk produced an even better
result than that of the previous morning!
Seeing was mainly fair but with just one brief good period when the
best AVI was captured. This will be the last clear/stable morning
for a while as the High Pressure is now moving East.
Orion Optics 245mm f/6.3 Newt + 5x Powermate = f/42.
ATiK 1HS + Red & Blue filters. Seeing briefly good for the best AVI.
Transparency fair/poor (very misty). Temp + 12 C.
Processed in Registax 3/Maxim DL/PSPro 8.

Here are some Mars images from the 18th. A bright morning limb haze extends from Hellas, across Libya into the NPH. The haze surrounding the SPC remains prominent.
14" (35cm) Celestron SCT @ f/39.5.
Lumenera LU075M CCD camera.
Seeing fair-occ good (Pickering 5-7.) Deteriorated later.
Transparency good (4.0mag) mist/haze.
No wind. Heavy dew.

Seeing just fair with good transp (for a city), strange was that the ir image was far less in quality as the plain rgb image, the polar haze is visible

A second set with the Lumenera. Seeing was better. The parasites lines have been seriously minimised by shooting at 60 fps for R and G, with a stacking of 2000 frames each. The blue images are taken at 7,5 fps, as 60 fps isn't possible anymore.
