This proton flux plot contains the 5-minute averaged integral proton flux (protons/cm2-s-sr) as measured by GOES-11 for energy thresholds of >=10, >=50, and >=100 MeV. SEC's proton event threshold is 10 protons/cm2-s-sr at >=10 Mev. Large particle fluxes have been associated with satellite single event upsets (SEUs).
