解説（安達）
　瀧本氏（香川）の画像では、北極の白雲がしっかりと記録されている。同じ
傾向が続いている様子を記録している。パ−カー氏(D.C.Parker)の画像ではア
エテリア(Aetheria;240W,+40）やウートピア(Utopia;260W,+50)付近にある暗
斑を記録している。また、この付近一帯が暗くなっており、北極地方の南限を
はっきりさせている。また、北極地方の白雲は２つに分かれて記録されている。
南極付近の白雲はしだいに濃くなってきているようだ。

February 3rd, 2004.
A white cloud is recorded in the north pole with the image of Takimoto.
This does this tendency, and rose follows it. Dark spots of Aetheria
(240W,+40) and Utopia (260W,+50) are recorded with the image of D.C.
Parker. And, this neighborhood is dark. South edge of Arctic hood is
made clear. An Arctic cloud is divided into two. The Antarctic cloud
becomes thick gradually.

          模様が出てきた。アルギュレは明るい。南極冠は見えなかった。

The South Polar Hood appears
to be forming. The Syrtis Blue Cloud is visible, and some dusky markings
are present east of Syrtis Major. Is this a revival of the Laocoontis-Thoth
comples?
