A couple of websites state that Pioneer 11 discovered a new moon of Saturn during its 1979 flyby and nearly collided with it.
http://www.uwgb.edu/DutchS/CosmosNotes/voyagr00.htm The website says Pioneer 11 missed the previously unknown moon by only a few hundred km. http://www.uwgb.edu/dutchs/planets/satslid.htm Apparently the spacecraft inferred the moon's existance by the disturbances it created in Saturn's magnetic field. Is this right? Did Pioneer 11 nearly end its mission in an unforseen Deep Impact style crash? -------------------- It's a funny old world - A man's lucky if he gets out of it alive. - W.C. Fields.

We can also confirm that Pioneer 11 was the first spaceprobe to image Epimetheus, with photo F-12E taken 00:29 hrs, 1979-SEP-01. The F-ring and Tethys are also visible:
The Saturn Viewer produces a plot of the same situation albeit as seen from Earth; here, the view is from beneath the ring plane (Pioneer was above it). Adding to the confusion is Dione, which is somewhat in the foreground and out of Pioneer's field-of-view in the image above. But the issue is seemingly settled: 1979 S1 was indeed Epimetheus:
