Bright Region in the C-Ring

Caption NASA:"This bright, isolated plateau in the middle of the C-Ring displays interesting internal variations in brightness. The plateau is not high in terms of elevation, but rather in terms of its particle density (seen here as brightness), which is several times higher than the surrounding Ring Structure.
Ring scientists are working to understand what produces the sharp boundaries of the plateau features, as well as the nature of the internal variations in brightness.
This view looks toward the sunlit side of the Rings from about 18° below the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 12, 2007 at a distance of approx. 230.000 Km (about 143.000 miles) from Saturn. Image scale is roughly 1 Km (3353 feet) per pixel".
