Abstract

The experimental data of active ionosphere experiment “North-star” are revisited.During the experiment, the plasma jet was injected into the ionosphere plasma transverse to geomagnetic field. A prolonged glow of the plasma cloud was observed. Anomalous ionization, low frequency waves and plasma heating were detected. The asymmetric azimuthal distribution of superthermal electrons indicates the presence of an intense transverse DC electric field. A change in the dynamics of a plasma jet under the influence of this factor is considered in this paper. The external DC electric field and electrostatic ion-cyclotron drift waves on density/temperature gradient along the transverse DC electric field play a role in plasma heating.
