GEO Proton Flux Alerts

Current Conditions

The description of the current state of the proton radiation environment at GEO attributed to SEP activity is based on the latest available NGRM proton flux measurements at three energies. For each energy, 5.5, 9.0 and 45 MeV, the categorical variable SEP activity receives the value YES when the current measurements exceed the empirically derived background noisy flux levels. The relative differences [(value-reference)/reference] of the latest hourly averaged differential proton fluxes with respect to the averaged values of the proceeding hour are also provided per energy channel.
