The evening mist in the vicinity of Syrtis major (290W,+10) prominent
observed. White clouds in the vicinity of Mare Acidarium (30W,+50) were
observed very brightly. As for the surface,the contrast is overall low,
and the pattern is elusive. The pattern is not seen easily because it
covers with the veil with the visual observation. A usual pattern comes
into view when the image raises the contrast. In a blue image of the
image of Christophe Pellier,the belt of white clouds is recorded in the
high latitude of the southern hemisphere provinces. This latitude appears
in succession with the region where the morning mist is observed always
brightly. The condition that the fog occurs easily seems to be
satisfactory in this region. The image of Damian Peach is recorded to a
very detailed part. The state not seen easily as usual continues to Nix
Olympica. (reported by 13 observers)

Mars,Dec 10 To the webmasters/observers

This set is the result of observations from Dec 10,under fair seeing conditions.
-There is going on definitely a strong activity of clouds in the southern polar regions.

-futher,the orographic Arsia cloud is still obvious but much smaller then before opposition.
-It appears Olympus Mons has turned back to dark but is not very obvious in all wavelengths
but there are some interesting clouds in that region.
The large clouds above Electris and Eridania,were already very obvious in the blue light
as seen live on the monitor screen.

As for christophe,the seeing was relatively good saturday evening and
here is a drawing I made. The following evening,with similar CML,there
may have been a few changes (in cloud cover) in the south of M. Sirenum
and also on the NPH (less extended close to terminator?)
[Nicolas Biver  MEUDON,FRANCE]

These two images were actually taken at different f ratios,then scaled in
Photoshop to look the same. This demonstrates clearly the effect to anyone
who was in doubt - even in poor seeing,you are only exploiting the Toucam
properly on bright planets with a focal length of at least 250 inches
(6.25m).

The earlier,low f image does however show blue haze on the S limb well,and
both images show Olympus Mons faintly. It certainly doesn1t look like it did
at opposition.
