Abstract :
Proton fluxes, linear energy transfer spectra, and single-event effects (SEEs) rates for the five solar particle events occurring during October 26 to November 6, 2003, are compared with previous events of the current solar maximum and with environment models. It is shown that this period includes the worst week for the current solar maximum and that this exceeds the October 1989 worst week in protons but not in ions. The SEE rates illustrate the importance of allowing for both proton and heavy ion contributions, the relative importance of which varies from event to event and with time during individual events.
