Results are described from energetic particle detectors onboard the Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX) satellite. Electron data are shown for energies E>400 keV in the outer zone of electron trapping (L≳3). The processes by which electrons are accelerated to very high energies (E>1 MeV) are discussed. Data are sorted according to L‐values and are compared with concurrent solar wind and geomagnetic conditions. Data from SAMPEX are also compared to GOES and UARS measurements. It is found that high‐speed solar wind streams drive the acceleration and recirculation of electrons throughout the outer zone on time scales of one day (or less). Very high time resolution measurements from SAMPEX show the very sporadic nature of magnetosphere‐atmosphere coupling processes.
