Patterns in the New SLS5 Longitude System in Saturn's Magnetosphere
Abstract
Very interesting patterns emerge when observations from all 13 years of the Cassini mission are transformed into the new SLS5 longitude system. The SLS5 system uses radio-emissions to define a variable-period longitude system with a north and a south branch. For instance, the component of the magnetic field displays a consistent east-west hemispheric asymmetry of amplitude 0.5 nT, which translates into a similar pattern of ±4 pico-Amps/m2 in perpendicular currents at the equator. Interestingly, there do not seem to be any spiral patterns in the long-term magnetic fields. The energetic charged particles also exhibit patterns, but any spiral-like patterns seem to be confined only to certain temporal epochs and to not persist throughout the entire mission.
