Please Note: Proton fluxes are integral 5-minute averages for energies >10 MeV, given in Particle Flux Units (pfu), measured by GOES spacecraft at Geosynchronous orbit: 1 pfu = 1 p cm-2 sr-1s-1. SESC defines the start of a proton event to be the first of 3 consecutive data points with fluxes greater than or equal to 10 pfu. The end of an event is the last time the flux was greater than or equal to 10 pfu. This definition, motivated by SWPC customer needs, allows multiple proton flares and/or interplanetary shock proton increases to occur within one SWPC proton event. Additional data may be necessary to more completely resolve any individual proton event.
Different detectors, onboard different GOES spacecraft, have taken the data since 1976. These proton data were processed using various algorithms. To date, no attempt has been made to cross-normalize the resulting proton fluxes.
Flare associations are given, although data about individual coronal mass ejections (CMEs), available from SOHO only since 1996, are necessary fully to characterize each event.
