The structure of this radiation belt is almost perfectly stable for more than 5 years of Cassini observations, despite the intense variability of the radiation belts, outside the location of Tethys.

ScienceDaily (Sep. 21, 2009) — Scientists using the Cassini spacecraft's Magnetospheric Imaging instrument (MIMI) have detected a new, temporary radiation belt at Saturn, located around the orbit of its moon Dione at about 377,000 km from the center of the planet.
The discovery will be presented at the European Planetary Science Congress in Potsdam by Dr Elias Roussos on Monday 14 September.
