解説（安達）
　DCパ−カー氏からの画像では、オーロラ(Aurorae sinus;50W,-10)の南方が
明るくなっている。本来はもう少しくらい部分であるところから、この部分に
ダストが覆っている可能性がある。この分解能なら南極冠が見えていてもおか
しくないのだが、全く判らない。極付近はダストに覆われているようだ。

January 16th, 2004.
The south of Aurorae sinus (50w,-10) is light with the image of D.C.
Parker. Originally, it is an a little more dark area. It has
possibility in this area dust. SPC can't be seen from this image,
and the extreme neighborhood seems to be covered with dust.
