摘要：
Simultaneous observations by EISCAT and the Kilpisjarvi all-sky camera revealed the presence of a band of enhanced electric field on one side only of an auroral arc. Both the arc and the enhanced electric field drifted equatorward at a velocity close to the prevailing convection velocity. The same drift speed was indicated by EISCAT measurements of ion-frictional heating: this descended in height as the magnetic field lines carrying the enhanced electric field cut across the EISCAT beam.
