Abstract Multi-spacecraft observations by Helios, IMP, and Venera show that interplanetary shocks can extend up to more than 90° east of the flare normal and are capable of accelerating particles, in particular protons up to energies of some tens of MeV. At the flanks the shock speed and the acceleration efficiency decrease; this decrease is more pronounced in high than in low energy protons. Shock spikes can be observed at energies up to 50 MeV and shock acceleration seems to be very effective inside 0.5 AU.
