Because it appears to pass behind Dione and because Dione was almost directly at its furthest from Cassini at the picture time, the target object (if a satellite of Saturn) must be in an orbit exterior to that of Dione. I tried matching the moon's ephemeris from Cassini's pictures with the named smaller moons (Kiviuq, Narvi, Ymir, etc) using JPL's Telnet, but couldn't find a match. I'd say it might be one of the as-yet-unnamed moons (the S/2004 bunch), except I doubt they'd be bright enough...

That shape, it's somehow... ...familiar. Can't *quite* place it, though!
