今朝は久しぶりの撮像シーイングだった、のに、亀岡は薄雲 厚雲。 京都の方には雲が無い。
やっとのタイミングで２画像、  ほかの方々はどうでしたか？

・ＮＥＢｓからのフェスト−ンが増えて目立つようになってきました。
・ＥＺｓの明るさが目立ちます。
・ＳＥＢｓの濃部と淡部が規則正しく繰り返し、数珠つなぎのように

The Cassini-Huygens mission
South up

2000/10/01 15:26 UTC
This image of Jupiter was taken by the Cassini Imaging Science narrow angle camera through the blue filter (centered at 445 nanometers) on October 1, 2000, 15:26 UTC at a distance of 84.1 million km from Jupiter.
The smallest features that can be seen are 500 kilometers across. The contrast between bright and dark features in this region of the spectrum is determined by the different light absorbing properties of the particles composing Jupiter's clouds. Ammonia ice particles are white, reflecting all light that falls on them. But some particles are red, and absorb mostly blue light. The composition of these red particles and the processes which determine their distribution are two of the long-standing mysteries of jovian meteorology and chemistry. Note that the Great Red Spot contains a dark core of absorbing particles.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini mission for NASA's Office of Space Science, Washington, D.C. The imaging team is based at the Space Science Institute, Boulder, Colo.
