解説(安達)
北極地方は晴れてきたようだ。NPCと思われる白くて明るい斑点
が見られる。12月10日は白く広がっていたが、今日はスポット状
になっており、比較してみると晴れてきた様子が分かる。今回注目
されるのはヘラス(hellas;290W,-50)が今シーズン初めて白雲に覆わ
れたことだ。しかも、白雲の広がりは、ヘラスからやや北に広がっ
ており、広い範囲を覆っている。観測が始まって初期の頃は、アエ
リア地方(Aeria;310W,+20)に淡く暗い斑点ができているかに見え
たが、今回の観測の結果、新たな模様の出現のないことがはっきり
した。
The North Pole region seems to have brightened. The white
and bright spot which seems to be NPC is seen. In December
10th, the North Pole region was widely covered, being white
but today, it becomes shaped like the point. When comparing,
it finds that the north Pole brightened. It is that the
observation of the first time and white cloud was gotten by
the Hellas(290W,-50) that attracts attention this time. White
cloud is spreading from the Hellas to Syrtis major, too.
It thought to the style where the loght pattern formed in
the Aeria( 310W,+20) in the early stages of this season but
not to be in the observation this time was cleared.

Hi all,
Here are some Mars images from Dec 19th showing the Moab area on the CM.
Hellas was bright (easily noted visually at 490x.) The NPC also appears
bright, again also noted visually.
Best Wishes
