西経０°付近でみると、北極と南極の周辺に、今日も晴れている部分が見える。中田氏の画像では、2日前から見られているMare
Sirenum付近の淡いダストベールが今日も同じ位置にあることを示している。この画像だと、淡いベールが確認できる。
畑中氏と堀内氏はDaedariaの北側に目立った白雲を記録している。これはTharsisのArsia Silva MonsとPavonis Monsによる
山岳雲の連なったものだ。
Gianluca Bianchi氏の画像は裏返しの画像なので、注意して見てください。
In the vicinity of 0 ° west longitude,we can see the sunny areas around the North Pole and the South Pole today as well. In the image
of Mr. Nakata,it shows that the light dust veil near Mare Sirenum seen from 2 days ago is in the same position today. With this image,
a light veil can be confirmed.
Mr. Hatanaka and Mr. Horiuchi are recording noticeable clouds on the north side of Daedaria. This is a series of mountain clouds
by Arsia Silva Mons of Tharsis and Pavonis Mons.
Please note that Mr. Gianluca Bianchi's image is an inverted image.

夕方まで晴れ間がありましたがこの画像の後に完全に曇りました。日本時で20時前の火星です、ノイズが出てしまいました。

夜になっても昼の熱気が残り川底を見るようなシーイングでしたが、南中を過ぎる頃になってようやく落ち着いてくれました。

Well,despite of the wind gusts,which was a bit lighter than early evening,
Mars shone brightly overhead crossing the zenit as I tried to get some RGB sequences,
Conditions were not great but some interesting albedo features were recorded nicely:
Aeria,Syrtis Major,Crocea,Trinacria,Iapygia,Mare Serpentis,Mare Ionium,Hellas,
Mare Australe,Sabaeus Sinus,Deucalionis Regio,Pandorae Fretum and other larger regions at the north of Mars.
I think the blue chanel is presenting some slight blue clearing.

砂嵐 も薄くなってきたようで、晴れてきたかな？ この地域は、元々薄かったようだが。 肉眼でも模様が見えていました。

曇天の回復を待ち撮影。火星はコンビニ店上空で、室外機による気流乱れあり。

Despite residual Jetstream,conditions were improved last night after the recent cold front had moved through.
Elysium at lower right and Olympus Mons just appearing at lower left. Mare Cimmerium stretching across the upper section of the image.
Regrettably having a persistent edge artefact which is affecting the SPC.

While waiting for Perseids,
I made an observation of Mars using Pete Lawrence's C14 telescope in Selsey West Sussex.
Although drifting cloud was a nuisance seeing was average and there was some nice details on the disk.
Syrtis Major can be seen on the following side,
the Hellas Basin was rather bright and there seemed to be an interesting shading separating Eridania and Ausonia.

This is an interesting view because although the dust was clearing and albedo features
which had been hidden for weeks were making their reappearance,
there are still thick dust clouds at the central meridian and around the Tharsis shield volcanoes.
Dust can still also be seen pooling in the canyons of the Valles Marineris near the eastern limb (left) in this image.
Olympus Mons however, seems to be well clear of any remaining dust and had a very red colour at this time.
White cloud appears just south of the north polar region at the bottom in the image.
The very blue hue of this area is very clear. Already slightly gibbous the planet was 98% illuminated at this stage,
but still retained a large apparent diameter not far off that of closest approach.
