解説(安達)
海外からの観測が集まりました。フランスのペリエ氏(Christophe
Pellier)からは、ダエダリア・クラリタス(Daearia:120W,-30)付近
の画像が送られてきました。ブルーの画像ではタルシス(Tharsis;90W,
+10)にある3つの山に白雲のかかっている様子が捉えられています。

2003,May,31st
An image was collected from the foreign countries. Cristophe
Plellier observed the neighborhood of Daedaria(120W,-30). Cloud
can be seen in the mountain of Thrsis (Tharsis;90W,+10) and it
understands the state well by the blue image. However, cloud can
not be yet seen in Nix Olymoica(125W,+20). It seems to become
in the afternoon in Mars and it may be possible to match. David
Moore observed the neighborhood of Mare Tyrrhenum(240W,-25). SPC
can be seen with a rough face. It isn't possible to judge only
from the image of this blue image but there is possibility that
blue clearing is sprung. It is because Syrtis major(290W,+10)
falls clearly too much, too, too much. Of the occurrence of blue
clearing not moved in the image of Eric Ng. The part at the center
of SPC which was made dark and white cloud near the North Pole
can be well seen. Guilherme Grassmann observed the state that
Tharsis(95W,+10) becomes white. Nix Olympica(135W,+25) doesn't
become white even if it becomes in the afternoon. It still seems
that there is little steam in the atmosphere. In-Joon-Hawang
is observing Edom(240W,-25) which was made bright. It is recording
the place to have become bright partially to Deucarion(350W,-20).

Hi all, Mars this morning in good seeing but poor to fair transparency. This
is the first time I use a good Astronomik filter for the blue image, and
despite the hazy/cloudy sky the image is yet better than the previous ones
with the wratten filter.
Again the same shadowy areas are noticed in the SPC. Clouds over Tharsis
and in the first image Solis Lacus comes into view.
Best wishes

Dear friends
The sky continue clear, but it also continue bad seeing and poor transparency
due to the strong easterly airstream is affecting south China coast.
The worst thing is quite strong wind occured while imaging.
Attached is the best one I could captured from a dozen of avi recorded.
The CM is similar to the one I posted yesterday.
The image was stacked with 500 raw, so it appears a bit noisy.
he dust streak is barely visible and seems moving towards Solis Lacus region.
May someone kindly comment on it.
Polar hood is visible and the limb brightening is not as obvious as previous two days.
Clear, steady and high transparent skies.
