解説（安達）
　前日と変化は見られない。アエテリア(Aetheria;240W,+45)付近に淡い暗部
が見える。北極は白く明るい。DCパーカー氏からは詳細な観測が送られてきた。
１２月の終わり頃に見られたソリス(Solis lacus;
90W,-25)付近に見られた淡いベルトは見えなくなっている。画像を注意深く見
ると、フリクシ(Phrixi regio;75W,-43)が確認できる。アルギレ(Argyre;30W,
-50)からこの明部を通ってバンド状に見えていたのかもしれない。南極北極と
も明るいが、色が違い、南極はダストに覆われているように見える。青画像か
らは北半球に雲の出ていることが良く判る。時間と共に明るくなるところから
地形による白雲と思われる。
（reported by 3 observers)

January 14th, 2004.
A change isn't presumed previous day compare. A dark area can be seen
faintly around Aethria (240W,+45). The north pole is white and light.
D.C.Parker has reported an excellent image.
A faint belt around Solis lacus (90W,-25) seen in about the end in
December can't be seen any more. Phrixi regio (75W-43) can be confirmed
when an image is seen carefully. It passed through this neighborhood
from Argyre (30w,-50), and it might seem to be a band-shaped.It seems
that a color is wrong though the south pole and the north pole are
light. The south pole may be covered with dust. A white cloud is
recorded in the Northern Hemisphere from the blue image. It seems to
be light with the time. This is probably a cloud by the geographical
features.

コメント：北極が白く輝いている。キムメリアの見え方もこの時期としては良い。
          昨日に比べて火星面の状況が良くわかる。
          The North Pole is shining white.
          How whose CIMMERIUM is visible is also good as this time.
Compared with yesterday, the situation of a Mars side is known well.

Also, here is the URL for a REALLY NEAT program for telling what time it
is on Mars for the various landing sites. Also  has all kinds of map
projections, orbits and other good stuff. Will work with Macs or Pcs.
