Abstract

Using high-latitude observations by the Polar Geophysical Institute, the development of a typical auroral substorm on September 13, 2013, is traced. The event, according to satellite data, is linked to solar wind parameters, physical magnetospheric domains, and boundaries. The characteristics of the spatial structure of polar auroras (scaling indices, anisotropy) have been determined for typical auroral structures (quiet and rayed arcs, breakup, pulsating bands, omega structures).
