3-day GOES Proton Flux plot

This proton flux plot contains the 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 >t=10 Mev. Large particle fluxes have been associated with satellite single event upsets (SEUs).

August 26, 2008 -- The GOES 11 spacecraft eclipse season starts September 1 and will continue for about 40 days (October 10). Maximum daily outages will reach about 65 minutes around September 20 in the middle of the eclipse season.
