Observations of solar energetic particles and shock-accelerated particles
observed by the KET on board the Ulysses spacecraft in the time interval
26 October 1990 to mid November 1991 are presented. Prompt events
with diffusive propagation were observed mainly at small radial distances while
at larger distances shock-related events became dominant. Particularly high
intensities of high energy electrons and more than 30 MeV/n nuclei are
observed at merged or double shocks. Slowly-varying populations with long
time scales neither related to prompt events nor to local shock effects are
a new feature at these intermediate distances.
