SOLAR PLASMAS. “As the magnetospheric activity conditions are largely controlled by the stability properties of the cross-tail current sheet, and as the magnetotail current sheet shares many of the properties of dynamically important current sheets found e.g. in the solar plasmas, the dynamics of the cross-tail current has been intensively studied in recent years.”
