We present results from the ionospheric heating experiment conducted at the High Frequency Active Auroral Research Program (HAARP) facility, Alaska. During the experiment, HAARP transmitted in the direction of the magnetic zenith X-mode 4.57-MHz wave. The transmitted power was modulated with the frequency of 0.9 mHz, and it was pointed on a 20-km spot at the altitude of 120 km. The heating (1) generates disturbances in the magnetic field detected with the fluxgate magnetometer on the ground and (2) produces bright luminous spots in the ionosphere, observed with the HAARP telescope. Numerical simulations of the 3-D reduced magnetohydrodynamic (MHD) model reveal that these effects can be related to the magnetic field-aligned currents, excited in the ionosphere by changing the conductivity in the E region when the large-scale electric field exists in the heating region.Sudden changes of the solar wind dynamic pressure have significant impacts on the dynamics of the magnetosphere-ionosphere system, a sudden decrease in solar wind dynamic pressure was observed by the Wind satellite, which drove the entire magnetosphere-ionosphere system as recorded in many ground-based and space-based.
