Ionosphere aurora borealis
WebAURORAL DISPLAYS INDICATE that the ionosphere and our protective atmosphere are being energized by the electric power generated in the magnetosphere. As these electrical currents are discharged in the ionosphere many phenomena are produced, including the visible emissions we recognize as the Aurora and magnetic storms.
