The effects of corotating interaction regions (CIRs) on energetic particles were first studied in detail about 30
years ago. The three-dimensional extent of CIRs and its importance in
structuring the quiet heliosphere, however, became obvious first from Ulysses observations at high
heliolatitudes. Mid 2007 the energetic particle fluxes measured at the position of Ulysses at about 1.5 AU and
about 30 degree South, at SOHO, close to Earth, and at the location of the two STEREO spacecraft show
pronounced solar rotational variation. From July to September 2007 a series of CIRs are observed. In this paper
we investigate the longitudinal and latitudinal variation
of the paricle modulations and the correlation to coronal hole structures seen in synoptic maps.
