Contents
Since June 1992 the Kiel Electron Telescope on Board ULYSSES measures 26-day
variations of the order of 6% in the fluxes of high energy H and He.
In May 1993 ULYSSES entered into the unipolar region of the southern polar
coronal hole, but continued to observe similar effects: increases in the
MeV proton channels due to acceleration near the shocks of the corotating
interaction region and decreases in the intensity of galactic nuclei associated
with the same region.
Amplitude variations are presented for different magnetic rigidities and the
effects are discussed in view of corotating shock development in a
3-dimensional heliospheric structure.
