The impact of high-energy (relativistic) electrons on orbiting
satellites can cause electric discharges across internal satellite components,
which in turn leads to spacecaft upsets and/or complete satellite failures.
The Relativistic Electron Forecast Model predicts the occurrence of these electrons
in geo-synchronous orbit.
Plots and data are updated daily at 0010 UT. Dashed vertical lines indicate
the last vertical value.
When the input parameters are not available, the forecast is not shown.
