Abstract

This chapter shows an example of Data Relay Technology Satellite (DRTS) anomalies. Highly energetic electrons in the outer radiation belt disappear during the main phase of the magnetic storm, and rebuilding of highly energetic electrons is made during the recovery phase of the magnetic storm. Increase is caused by the supply of intermediate-energy electrons by the substorms and these seed electrons are accelerated internally up to the MeV energy range by the intense plasma waves. The distance of the new peak of highly energetic electron flux from the Earth is inversely proportional to the amplitude of the magnetic storm. Integration of the magnetic activity index is a good proxy for the increase of the flux of MeV electrons not only at the geostationary orbit altitude but also in the outer radiation belt that gives a clue for the radiation belt forecast.
