Energetic electron bursts at high magnetic latitudes: Correlation with magnetospheric activity Original Research Article

There is considerable interest on the origin of high energy electron bursts recently observed at high magnetic latitudes by dosimeters on the GPS satellites. The energy of these electron bursts can be as high as 500 keV. These bursts are seen in regions that map onto open field lines and where normally observed fluxes are at background levels. In this study we examine the distribution of these events, and correlate them with magnetic indices and solar wind magnetic field data. Our results indicate many of these electron bursts are likely to be substorm-associated.
