Three‐Dimensional Currents in Saturn's Magnetosphere

Abstract: Observations of Saturn's magnetic field from July 2004 to December 2016 have been combined to allow a numerical calculation of ∇ × B throughout the magnetosphere, thus permitting the first global mapping of Saturn's currents in three dimensions. The azimuthal ring current Jϕ dominates the magnetospheric currents, peaking near the orbit of the moon Rhea and having a total magnitude of over 10 mega‐Amperes integrated within the L‐shell of Titan. In meridional cross section, the ring current has a teardrop shape … Show more

“…The ring current is concentrated between 5 and 15 R S and has a peak strength of ~0.25 MA/R S 2 ≈ 70 pA/m 2 , which is crudely similar to the block model. These results are in general agreement with previous estimates of the location and strength of the ring current (Bunce et al, ; Carbary, ; Kellett et al, , , ; Sergis et al, , , ).…”

“…Figure shows the azimuthal current maps in four local time sectors. These are essentially the same maps shown in Carbary () except the binning has been extended down to ~2 R S . A number of bins had to be filled in (red crosses) even though magnetic field data from several seasons were used.…”
