The paper provides a detailed description of energetic ion measurements from the Energetic PArticle Composition instrument (EPAC) and magnetic field measurements from the dual-technique magnetometer on board Ulysses made in the duskside Jovian magnetosphere after its Jupiter flyby on February 8, 1992. The Ulysses spacecraft performed these in situ measurements on its outbound trajectory passing through the local time sector between 2100 and 1830 from northern to relatively high southern latitudes. The outbound pass is divided into six different regions, which are differentiated by magnetic field measurements and by the behavior of the particle intensities, ion spectra, and composition, as well as ion anisotropies. At a distance of 21 RJ the energy spectrum of 0.57--1.42 MeV protons suddenly becomes much softer, indicative of a transition between a dipolar-like inner magnetosphere and the inner edge of the plasma sheet. The EPAC instrument observes a dramatic increase in all particle intensities at distances around 50 RJ at southern magnetic latitudes of 30 ¿S. The intensity levels are as high as those observed during the inbound equatorial plasma sheet crossings at comparable distances. The increase is interpreted as a temporal phenomenon associated with a thickening of the plasma sheet. After the first magnetopause crossings at distances near 80 RJ, EPAC measurements reveal signatures of magnetospheric particles existing in the magnetosheath which imply that the Jovian magnetosphere is open. Following a change in the interplanetary magnetic field orientation, these particles are then no longer observed within the magnetosheath. A further puzzling particle observation along the Ulysses outbound pass is the reentry into the magnetosphere between 115 and 124 RJ at 37¿ southern magnetic latitude. It impressively shows the high variability of the Jovian magnetosphere. ¿ 1999 American Geophysical Union
