AB: We present initial results from a study of global and local auroral electrodynamics in pseudo-breakups. These short-lived localized auroral disturbances have a typical lifetime of tens of minutes and a spatial size of hundreds of kilometers. Pseudo-breakups occurring after a quiet period were identified by the use of the Polar VIS Earth Camera. The spatial and temporal morphology of the auroral electrojet configuration is studied by the use of SuperDARN line-of-sight convection measurements and all available ground based magnetometers. In addition FAST measurements are used whenever possible.
