A Survey of Known Indicators of Auroral Substorm Onset.

Abstract

This report summarizes current research in the area of auroral substorm prediction. Long term indicators are investigated; in particular the solar cycle solar flares coronal holes, and the tendency for these phenomena to recur. Short term indicators are also reviewed: recurrence probability in Defense Meteorological Satellite Program images, the solar winds and the interplanetary magnetic field, the equatorward boundary of the auroral oval, electron density dropouts at geosynchronous orbit, visual observations from the ground, magnetometers measurements, auroral radar and riometer measurements. Keywords: Auroral substorm prediction; Substorm onset; Equatorward boundary.
