Data-based models have been derived to forecast the >0.8MeV and >2MeV electron fluxes at geostationary Earth orbit. The models employ solar wind parameters as inputs to provide an estimate of the average electron flux for the following day, i.e. the 1-day-ahead forecast. The identified models are shown to provide a reliable forecast for both >0.8MeV and >2MeV electron fluxes and are capable of providing real-time warnings of when the electron fluxes will be dangerously high.
