A broad and ghostly spoke drifts past under Cassini's gaze. The spoke-forming region of the B ring displays faint longitudinal variations in brightness, from left to right, a feature seen in other images (see PIA08300).

This view looks toward the unlit side of the rings from about 35 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 17, 2006 at a distance of approximately 2 million kilometers (1.3 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 158 degrees. Image scale is 12 kilometers (7 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.
