Local Acceleration of Auroral Electrons
Electron precipitation in the vicinity of auroral arcs is discussed. The energy spectra and degree of field alignment are interpreted in terms of an acceleration model in which the energy gain is distributed randomly about the mean value. Some suggestions are made for definitive future measurements.
