Abstract
Observations of auroral dynamics in the polar cusp region is used to derive regularities of the time and space distribution of large-scale electric fields at the magnetopause and in the polar ionosphere. The interpretation of experimental data is based on the supposition that the magnetopause electric field (the reconnection electric field) consists of the potential and vortex components which have different sources in the magnetopause vicinity, and different signatures in the polar ionosphere.
