摘要

One of the fundamental problems in modern astrophysics is the propagation of cosmic rays in turbulent magnetic fields, which can be studied by way of in-situ measurements of energetic particles in the heliosphere. Between 1 and 10 AU Jovian and galactic particles contribute continuously to the few-MeV electron intensities. As a result of this a 13 month period in the MeV electron intensity time profiles is observed at Earth. During its recent ascend to high latitudes the Ulysses spacecraft approached the planet Jupiter within 1 AU. 3-20 MeV-electrons were measured by the Kiel Electron Telescope (KET) on-board Ulysses from 1990 to 2006. At solar maximum Jovian electrons could unambiguously be identified at heliographic latitudes beyond 40°N and 10 AU from the planet. In this contribution we will present results of an analysis of Ulysses KET MeV electron measurements from the recent third out-off-ecliptic path and compare these data with observations obtained from 1992 to 1994 when the spacecraft was leaving the planet.
