There are several interesting things to watch for in this portrait of Saturn from the narrow-angle camera on board Cassini.  Subtle cloud textures are visible in the northern hemisphere. In the thin shadow of the F-ring (the upper-most ring shadow) there is a lump at center left, cast by a knot or clump in the twisty ring. At the lower left, the rings reveal themselves to be as thin and translucent as fine vellum. The circular artifact at the lower center of the rings is a flaw in a camera filter, and not an actual object.

 

At right is an image, also taken this week, of Saturn’s complex and violent clouds, including several large storms in the south.
