High-energy electrons in the earth's magnetosphere in different phases of a magnetic substorm
Abstract
The behavior of energetic (20 keV to 1.4 MeV) electrons during magnetic substorms is analyzed on the basis of satellite data. A substorm model is elaborated with representation of extended involved magnetospheric disturbances and tie-ins with geophysical data. The most typical and general properties of electron dynamics in various substorm phases are examined. Regions of electron acceleration which are localized in latitude correlate with regions of activation of magnetic disturbances. Two mechanisms are proposed for a substorm rise in electron flux on the daytime side of the magnetosphere.
