コメント：１週間ぶりの撮影となった。今年の連休は最悪の天候で、
夜に星が見えなかった期間が最大となった。
土星の高度も低くなり、また小さくなったが変化は無い
ように思われる。

The Cassini-Huygens mission
South up South up Original image tif 214kB

Two pairs of dark spots, or storms, in Saturn's atmosphere squeeze past each other as they dance around the planet. In this group of four storms, the top left and lower right storms are fringed with white clouds. The image was taken with the Cassini narrow angle camera in the near infrared on May 5, 2004, at a distance of 29.5 million kilometers (18.3 million miles) from Saturn. Image scale is 176 kilometers (109 miles) per pixel. Contrast in the image was enhanced to aid visibility.
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-Huygens mission for NASA's Office of Space Science, Washington, D.C. The Cassini orbiter and its two onboard cameras, were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
