Energetic ions observed by Ulysses in the Jovian magnetosheath

Karanikola, I.; Anagnostopoulos, G.

In this paper we present a survey of energetic (>∼50 keV) ion and (>∼40 keV) electron measurements made in the Jovian magnetosheath by the (Heliospheric Instrument for Spectra, Composition and Anisotropy at Low Energies) experiment onboard Ulysses, during its flyby of Jupiter in February 1992. The most common characteristics of the magnetosh…

The effect of instrument limitations on the derivation of plasma flows from energetic ion anisotropies, with an application to Ulysses observations at Jupiter

Cowley, S. W. H.; Kolesnikova, E.

Plasma velocities determined from the anisotropies of energetic ions via the Compton-Getting effect have been important in studies of magnetospheric flows, particularly with regard to the magnetospheres of Jupiter and Saturn. In this paper we consider a range of issues concerned with the practical limitations of such measurements, and their effect…
