Unified Model of Auroral Substorm Development.
Abstract
The primary data base for this report on auroral substorm phenomena included DAPP/DMSP satellite images of auroras, selected mid- and high-latitude ground-based magnetograms, and newly developed ground-based photometric measurements of auroral emissions of great sensitivity. Extensive morphological and topological studies were made from the DAPP/DMSP images. An auroral activity index was developed and statistical correlations with magnetic indices determined. The persistence of aurora, and auroral zone, and the relationships between auroral activity with substorms and mid-latitude magnetic signatures were developed from satellite images. Models were developed from satellite images using midlatitude magnetograms to detect substorm occurrence. The photometric studies gave new information on the location of particle injection at substorm onset and on morphological characteristics of auroras in local time. The advantages of X-ray monitoring of the ionosphere from a polar orbiting satellite are described; and statistics of the solar wind electric field determined.
