Scientific paper

Observations of magnetosheath plasma intrusion made by Viking in the dayside magnetosphere at auroral latitudes are presented. The intrusion is not connected with the well-known quasi-steady state entry of magnetosheath plasma in the cusp regions; rather, it is of a temporal, transient type. Since these intrusion events are observed on flux tubes which are populated by background boundary layer plasma and which were shown to map close to the magnetospheric boundary, it is concluded that they are the midlatitude signatures of transient solar wind/magnetosphere interaction processes. The event distribution in MLT peaks well away from noon in the postdawn and predusk sectors. Although the occurrence probability in the dawn and dusk sectors is nearly equal, the dawnside events are generally more pronounced. It is inferred that the magnetosheath plasma intrusion events are related to ground-based observations of magnetic impulsive events or so-called traveling ionospheric vortices.
