摘要：

A discrete auroral are is set up by precipitating electrons. Current continuity requires a ret urn current fed by a horizontal current from the are. In the closing of this current system E-region plasma might escape along the return current, and if the source acts as a constant current generator the horizontal electric field can get enhanced. The existence and relative position of these features can be used to diagnose the state of the magnetospheric generator.
