ペリエ氏(Christophe Pellier)の観測では、南極冠の20Wの輝点がまだ健在で
ある様子がうかがわれます。また、南極冠の中央よりも向こう側に明るい点が写
っており、南極点付近は暗くなっている部分の端に位置する様です。今回の報告
で気になるのはノアキス(Noachis;350W,-40)の中央を右上がりにできている暗い
バンドがあることです。今回はこのバンドがよく目立っています。コントラスト
を上げたことによって出てきたのかも知れませんが、淡いダストのイタズラかも
しれません。アメリカのメリッロ（Frank J Melillo)の画像からは赤道付近の氷
晶雲が良く捉えられています。D.パーカー氏（D.C.Parker)の画像ではオーロ
ラ(Aurorae Sinus;50W,-10)やソリス(Solis Lacus;90W,-25)の様子が、線状に写
っています。肉眼ではこれほど極端に線状には見えません。ブルーの画像では低
緯度地方の氷晶雲にむらのある様子が良く出ています。

The brightish spot which is in 20 W of SPC can be still seen.
Christophe Pellier recorded this state. SPC can see the point which
is brighter with the reverse than with the center. That it does the
SPC center seeming of that it becomes the end of the dark part is done.
The dark band can be seen in the right rising at the center of
Noachis(350W,-40). It seems that it is the pattern which appeared
because it gave the contrast of the image. In the image of Frank J
Melillo, water ice cloud is conspicuous well in the place with low latitude.
In the image of D.C.Parker, Aurorae sinus(50W,-10) and Solis lacus
(90W,-25) fall like a line and the figure of line can not be seen at
the sticker, the naked eye. In the blue image, it finds that it isn't
spreading, that water ice cloud in the place with low latitude is
uniform.

Hello : this morning the seeing was the better I had so far on Mars, amazing
at the 22-26° altitude. This really give a change to the images, I hope I'll
have more mornings like this one ! I see no change in the Sinus Meridiani -
Syrtis Major area since the previous images taken from other places in the
world.

Solis Lacus is very prominent as a dark circular area. Note the details around it.
I had cropped and enlarged the SPC itself and it seems to have some darkening
spots and rifts inside the area.
