Variations in the polar cap area during two substorm cycles

Variations in the polar cap area during two substorm cycles

This study employs observations from several sources to determine the location of the polar cap boundary, or open/closed field line boundary, at all local times, allowing the amount of open flux in the magnetosphere to be quantified. These data sources include global auroral images from the...
