Prometheus' streamers

Caption NASA:"This view shows Prometheus with a streamer it has created in the inner edge of the F-Ring. Prometheus comes close to the inner edge of the Ring once per orbit, perturbing the Ring particles there.
In 2009, the moon's orbit is expected to carry it repeatedly into the F-Ring core, an event that ring scientists are eagerly awaiting.
Prometheus is 102 Km (approx. 63 miles) across. This view looks toward the unlit side of the Rings, from about 40° above the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 16, 2006 at a distance of approx. 1,8 MKM (1,1 MMs) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 150°.
Scale in the original image was roughly 11 Km (about 7 miles) per pixel.
The image has been magnified by a factor of two".
