  This Cassini view shows a bright storm which appeared in Saturn's southern hemisphere in mid-September and continued to evolve for some time afterward. This type of storm is a good candidate source for lightning because of its sudden appearance and high level of activity. Lightning can be detected by Cassini's cameras when the spacecraft is on Saturn's night side, and by the radio and plasma wave detector on either the day or night side.

Several dark ovals to the left and right of this storm mark the sites of other storms in this turbulent westward flowing region of the atmosphere.

The icy moon Enceladus (504 kilometers, 313 miles across) is visible near the bottom of the image.

This image was taken with the narrow angle camera on September 25, 2004, from a distance of 7.7 million kilometers (4.8 million miles) from Saturn through a filter sensitive to wavelengths of visible red light centered at 619 nanometers. The image scale is 45 kilometers (28 miles) per pixel.

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 Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
