FAST Observations of Electromagnetic Stresses Applied to the Polar Ionosphere

Abstract

The Fast Auroral Snapshot Explorer (FAST), with its 83 inclination orbit and 4000 km apogee, is ideally suited for investigation of the high latitude perturbations to the geomagnetic field. These data can be used to determine fieldaligned currents, but here we emphasize the perturbations themselves, rather than their spatial gradient. This allows us to more… (More)
