解説(安達)
NPHはやや明るさが低くなった。画像からは、低緯度地方以外はリムが黄色
くなって、両極地方がダスティーになっていることが分かる。ブルークリアリ
ングは今日もシルチス・マイナー(Syrtis Miner;260W,0)付近が見えている。
この様子は米山氏と柚木氏の画像で見ることができる。火星面は午前の半球で
朝霧が目立つようになってきた。特に、朝霧の特に濃い部分が、南半球に見ら
れるようになった。この様子はChristophe Pellierの画像で良く分かる。
(reported by 17 observers)

Brightness has lowered to NPH a little. The limb yellows from the
image excluding the low latitude provinces,and it is understood that
the two poles provinces are dusty. Blue clearing sees the vicinity of
Syrtis Minor (260W,0) today. This appearance can be seen in the image
of Yoneyama and Yunoki. The morning mist has come to conspicuous in
the hemisphere in the morning side on the Martia surface. Especially
the part where the morning mist was especially thick came to be shown
in the southern hemisphere. This appearance is understood well from
the image of Christophe Pellier. (reported by 17 observers)

22時過ぎに雲が晴れて何とか撮影出来ましたが
シーイングもかなり悪く、また明朝早起きしなければ
ならないので1回の撮影で終了します。
450nm以下でのブルークリアリングは確認できません
でしたが、周辺部分以外に、中央部分の明るさに変化が
あるようです。雲でもあるのでしょうか。

Fitsファイルも送付します。

 不安定な冬型の天気で、シーイングも悪く写りも悪いですが
大シルティスあたりの青白いベールが目立ちます。

このところ、雲一つないので撮像の準備をすると突然雲が出てくるので撮像が困難である。絶えず雲が押し寄せ、切れ間からの撮像となるのだが、薄い雲を透しての撮像になりがちでゲインが変化する。
ブルークリアリングはテュッレム付近を除き地表の模様と同定出来るものは、ほぼなくなってきている。北半球、南半球とも薄い雲や水蒸気のあると考えられる所以外は、模様と関係なく一様に暗く写っている。

コメント:シーイングが大変悪い。北極付近は青白い雲で覆われている。
シルチスが出てきた付近は朝霧のようです。相変わらずコントラストも低い状況です。

Despite the relatively poor seeing conditions,a distortion of the limb of the planet is visible. (arrow)
Can it be Charitum Montes? The phase is 0.992 and still unnoticeable.

My **BEST** Mars frames so far were captured last night in freezing and
very soon after,foggy conditions in deepest Suffolk,UK.

Margaritifer Sinus/Oxia Palus are near the meridian.

The image is at a similar longitude to the Oct 28th HST shot,i.e. when the
dust storm was near this region.

Seeing was fair !!! Almost unknown at this site !

Celestron 14 (356mm f/11 SCT) + 3 x Barlow = f/44
0.1 arcsecs/pixel (7.4 micron pixels)
Lumenera LU 075M + Red & Blue filters (Green simulated).

Temp 0C.... Dew starting to freeze and fog forming.
Transparency fair but deteriorating.....

Captured/converted with Streampix.
Processed with Registax 3/Maxim DL/PSPro 8.
Further details on the image.

Ian Sharp (200mm Newtonian ATIK-1HS)
Here are 2 imags from 18th Nov,one with the Toucam,and one with the ATIK.
I only used the Toucam as I was imaging with my kids and I wanted them to
see it in colour as we were recording it!
No resampling today - just 100% size.

here a image from mars 2005/11/18.
The seeing was not the best and several chimney on the roof spoil sharp images.

Some images from the night of 17-18. This was the first occasion I tried an
Astro-Engineering x1.6 Powermate to increase the EFR on Mars from about f30
to f48 (a 2x Barlow is too much on this telescope).

The IR images show some detail,but the colour composites have turned out
strangely technicolour. I don1t know whether this is the poor seeing
instrumentation,or my fault,but I couldn1t seem to process it out. G and B
images were very blurry this night.

Hi all,there was an inversion layer that night and seeing was excellent just a few hours before fog began.

http://www.astrosurf.org/pellier/M051118b-CPE (IR,violet,UV)
I like most the morning mists - much details can be seen on them. On the blue,violet,UV images they can even be followed as streaks extending into the morning sol (martian day)
I tried a true LRGB image. LRGB can bring a better resolution than RGB if seeing is very good,alhtough the image is more difficult to build at same level of quality.
A interesting word I think about this image - you can see some circular lines at the following side (morning) already seen back in october on some Damian and Dave Tyler's blue images... well I have the explanation :-)) it's an artefact caused by a reflection on some optical pieces (I don't know which). The ghost Mars located at left is visible in the original fit frame with proper level adjustment.

When I set up the telescope the seeing was very good,but afterwards
cloudies from sud-east covered part of sky and seeing was very poor.
