解説(安達)
非常に良く撮れた画像が報告されてきた。視直径が4.2秒とは
到底思えないすばらしい画像だ。
M.Frassati氏のスケッチでも捉えられていたが、アキダリウム
は非常にはっきりと捉えられている。注意深く調べると、ピーチ
氏も指摘しているように、バルティア(Baltia;50W,+65)が非常に濃く
なっている。また、アキダリウムの北東の角にある、カリンホエス
(Calinhoes;7W,+50)が東へ大きく広がったように見える。さらに
マリネリス渓谷のあるアガトダエモン(Agathodaemon;65W,-12)付近
も微妙な見え方をしているのが気になる。北極付近は白くなって
いるが、これは北極冠ではないようだ。
A very good image was reported from Damian Peach. The
diameter is as wonderful as not to seem 4.2. The image of
M.Frassati was taken but Mare Acidarium is caught very
thick. As Damian Peach points out, Baltia(50W,+65) becoms
very thick. Calinhoes(the corner in the northeast of Acidarium)
seems mainly spread to the east. Moreover, Agathodaemon
(65W,-12) is doing the way of that it is posible to see
which is subtle. It is the place which becomes a feeling.
It becomes white but the North Pole seems not to be NPC.

Hi all,
Here are more Mars images, this time from Dec 10th.
Seeing was good, and occasionally excellent (at last!)
for this session, despite the 25 deg altitude.
What strikes me most, is the markings around Baltia
seem very dark. Also a bright morning haze is present,
which i also saw visually. It also seems as though
coprates appears fairly dark.
Best Wishes
Damian
