Abstract
We present observations of solar energetic particles and shock‐accelerated particles observed by the Kiel Electron Telescope (KET) on board the Ulysses spacecraft in the time interval 26 October 1990 to mid November 1991. 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 >30 MeV/n nuclei are observed at merged or double shocks. Slowly‐varying populations (SVP) with long time scales neither related to prompt events nor to local shock effects are a new feature at these intermediate distances.
