| Zusammenfassung |
Using EISCAT radar data,
we find that electrons are strongly heated in the magnetic field-line direction
during high electric field events. The remote site data show that the electron
temperature increases in almost the same way in the field-perpendicular
direction; electron heating by E region plasma turbulence is isotropic. We
discuss the implications of our observation for the "plasmon"-electron
as well as the wave Joule heating models of the anomalous electron heating in
the E region.
