Scientific paper

We investigate an event observed by the four Cluster satellites in the dayside high latitude auroral region around 80 ILat and 14MLT at an altitude of about about 5Re. The Cluster satellites were located in the auroral region for about 30 minutes, corresponding to several thousand km along the orbit. In this region, the magnetic field showed periodic perturbation of about 2 min., and the upward electron acceleration, usually located just beside the downgoing electron acceleration structures, had the same period. All Cluster satellites observed the periodic acceleration signatures, and hence, we expect that the spacecraft observed filament like auroral arc structures. Similar periodic structures of the electron acceleration and magnetic perturbations have often been observed in the dayside auroral acceleration region by the Cluster satellites. We discuss possible mechanisms to generate the periodic perturbations and their relationship to the auroral particle acceleration phenomena.
