Jupiter tail phenomena upstream from Saturn

Plasma wave and plasma probe measurements from Voyager 2 for February 1981 suggest the detection of phenomena associated with a well defined Jupiter tail, at a distance of about 6,200 Jovian radii. This is held to imply that the Saturn magnetosphere will be affected by the Jovian tail, and that insight into the physics of Saturn's magnetosphere may be obtained through comparisons of Voyager 1 and 2 data. Among the effects that can be sought in Voyager 2 data are magnetosphere size variations, bow shock location, radio emission strength and trapped radiation belt population.
