Statistical properties of the magnetic field in the Kronian magnetotail lobes and current sheet
Statistical properties of the magnetic field in the Kronian magnetotail lobes and current sheet
We examine the characteristics of the magnetic field in Saturn's magnetotail lobes and current sheet during the Cassini spacecraft's exploration of the magnetotail from day 18 to day 291 of 2006. During this period Cassini reached maximum downtail distances of ∼68 RS, with orbits at the beginning of the survey interval concentrating on the equatorial regions, while later orbits moved to somewhat higher latitudes. We find that the field strength in the lobes falls off as Blobe (nT) = (251 ± 22) × (r (RS))-1.20±0.03. We show that the lobes and current sheet have distinctive magnetic pressure distributions, and we examine the transition of the field from the central current sheet out into the northern and southern lobes.

Abstract
We examine the characteristics of the magnetic field in Saturn's magnetotail lobes and current sheet during the Cassini spacecraft's exploration of the magnetotail from day 18 to day 291 of 2006. During this period Cassini reached maximum downtail distances of ∼68 RS, with orbits at the beginning of the survey interval concentrating on the equatorial regions, while later orbits moved to somewhat higher latitudes. We find that the field strength in the lobes falls off as Blobe (nT) = (251 ± 22) × (r (RS))-1.20±0.03. We show that the lobes and current sheet have distinctive magnetic pressure distributions, and we examine the transition of the field from the central current sheet out into the northern and southern lobes.
