Abstract:
Accurate upstream predictions of the flux environment at GEO are highly desirable in order to evaluate the upcoming risk to orbital satellites and instrumentation. Knowledge of the expected flux, in the energy range from 1 eV to 40 keV, with a lead time of ~1 hour, would provide operators with information on the potential risks from surface-charging. Our current model (http://gemelli.spacescience.org/mdenton/) provides the electron and ion flux at any energy between 1 eV and 40 keV, at any local time, and at any value of the Kp index. We will discuss our current model of the electron and ion fluxes at GEO, and also highlight new additions to the model based on LANL/MPA observations ordered with respect to the IMF and solar-wind velocity at 1 AU. We will also discuss other factors (e.g. effects of magnetic latitude) that could potentially improve predictions of fluxes in the inner magnetosphere.
