3-day GOES Proton Flux plot

GOES 5-minute averaged integral proton flux (protons/cm2-s-sr) as measured by the SWPC primary GOES satellite for energy thresholds of >=10, >=50, and >=100 MeV. SWPC'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).
