ULYSSES observations of energetic particle acceleration and the superposed CME and CIR events of November 1992

Forsyth, R. J.; Keppler, E.; Kunow, H. +4 more

During November 1992, a series of forward and reverse shocks passed the ULYSSES spacecraft. Spectral and anisotropy measurements are reported for protons and alpha particles between 0.28 and 6 MeV observed by the Energetic Particle Composition Experiment, data recorded by the Magnetometer Experiment and the high-energy (2.7-300 MeV) proton data fr…

Recurrent variations of anomalous oxygen in association with a corotating interaction region

Fränz, M.; Keppler, E.; Reuss, M. K.

The fluxes of anomalous oxygen (E ranging from 3.5-6.8 MeV/amu), as measured by the EPAC instrument on ULYSSES, show a recurrent variation with the solar rotation period, which is anticorrelated with the fluxes of particles accelerated at the shocks of a corotating interaction region (CIR), and correlated with the fluxes of galactic cosmic rays kn…
