| Zusammenfassung |
For the first time during the mission, the
Anisotropy Telescopes instrument on board the Ulysses spacecraft measured
constant zero anisotropy of protons in the 1.3-2.2 MeV energy range, for a
period lasting more than three days. This measurement was made during the
energetic particle event taking place at Ulysses between 25 November and 15
December 1998, an event characterised by constant high proton fluxes within a
region delimited by two interplanetary forward shocks, at a distance of 5.2 AU
from the Sun and heliographic latitude of 17°S. We present the ATs results for
this event and discuss their possible interpretation and their relevance to the
issue of intercalibration of the two telescopes.
