Heating of ionospheric ions on polar border of auroral region
Abstract
Data of thermal ion heating on auroral polar border measured by Interball-2 (Auroral Probe) satellite is presented. When the satellite crossed of the polar cap on auroral polar border during high geomagnetic activity intense low frequency electromagnetic perturbations are detected. At the same time local heating of thermal plasma occurs. Near the border AKR generation not far from satellite also measured. In the presentation the mechanism of simultaneous thermal ion heating and AKR generation is discussed.
