Corotating Interaction Regions in the Heliosphere:Workshop Report

Abstract

In June 1998 a workshop was held at the International Space Science Institute ISSI, Bern, Switzerland, on "Development and effects of Corotating Interaction Regions in the Heliosphere". The workshop was the last of a series of three and the results will be published shortly in Space Science Rewiews and in the Space Science Series of ISSI. The development of CIRs throughout the Heliosphere as observed in plasma and field parameters will be discussed. Effects of CIRs include the acceleration of low energy charged particles and the partial rejection of galactic particles from the inner Heliosphere. Results from ULYSSES at high latitudes and from the outer Heliosphere show that the effects can be observed far beyond the actual extent of the CIR in the Heliosphere. The major results of the workshop will be presented in this paper.
