The impact of high-energy (relativistic) electrons on orbiting
satellites can cause electric discharges across internal satellite components,
which in turn leads to spacecraft upsets and/or complete satellite failures.
The Relativistic Electron Forecast Model predicts the occurrence of these electrons
in geosynchronous 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.

September 9, 2010 -- The observed electron values for the Relativistic Electron Forecast Model are now plotted for the GOES-13 satellite. GOES-13 is designated as GOES-East, located at 105 degrees W longitude, is in the best position for observing relativistic electrons. Previously, GOES-11 electron data was used, but since that is now in the designated West location, it is no longer the best option for providing the necessary data.
Historical electron particle data is archived at the
National Geophysical Data Center for
Solar-Terrestrial Physics.
