Caption NASA:"Wispy Terrain reflects Sunlight brightly in the lower left of this Cassini image of the Northern Latitudes of Saturn's moon Dione.
These "Wisps" are actually Fractures located on the Trailing Hemisphere of Dione. Lit Terrain seen here is between the Trailing Hemisphere and the Saturn-facing Side of Dione. North is up.

The image was taken in Visible Light with the Cassini spacecraft narrow-angle camera on Dec. 20, 2010. The view was obtained at a distance of approx. 107.000 Km (66.447 miles) from Dione and at a Sun-Dione-Spacecraft, or Phase, Angle of 109°. Image scale is roughly 640 meters (2100 feet) per pixel".
