Prange R, Rego D, Southwood D, Zarka P, Miller S, Ip Wet al., 1996, Rapid energy dissipation and variability of the Io-Jupiter electrodynamic circuit, Nature, Vol: 379, Pages: 323-325

THE electrodynamic interaction between Jupiter and the closest of its large moons, Io, is unique in the Solar system. Io's volcanoes eject a considerable amount of material into the inner jovian system (>1 tonne per second), much of it in the form of ions(1); the motion of Io through Jupiter's powerful magnetic field in turn generates a million-ampere current(2) between the charged near-Io environment and the planet's ionosphere. This current is presumably carried by Alfven waves(3), the electromagnetic equivalent of sound waves. Here we present far-ultraviolet observations of the atmospheric footprint of this current, which demonstrate that most of the energy is dissipated rapidly when the waves first encounter Jupiter's ionosphere; the position of the footprint varies with time, We see no evidence for the multiple ionospheric interactions that have been proposed to explain the structure of the radio emissions associated with these waves(4).

Magnetic field measurements from the Ulysses space mission overthe south polar regions of the sun showed that the structure and properties of the three-dimensional heliosphere were determined by the fast solar wind flow and magnetic fields from the large coronal holes in the polar regions of the sun. This conclusion applies at the current, minimum phase of the 11-year solar activity cycle. Unexpectedly, the radial component of the magnetic field was independent of latitude. The high-latitude magnetic field deviated significantly from the expected Parker geometry, probably because of large amplitude transverse fluctuations. Low-frequency fluctuations had a high level of variance. The rate of occurrence of discontinuities also increased significantly at high latitudes.
