- Аннотация: A series of heating experiments have been carried out in 2006 at the SPEAR heating facility on Svalbard. The experiments on modulated ionosphere heating were mainly aimed on injection of artificial MHD waves into the upper ionosphere. Ground based observations of the artificial magnetic pulsations near the heating site provided by the Polar Geophysical Institute at Barentsburg show some interesting features. Probability of their excitation is rather small (~10%) and independent of the K-index of magnetic activity. The density of background ionospheric currents estimated from magnetic disturbances during the intervals of artificial emission generation are in the range 100 - 200 mA/m, corresponding to moderately disturbed conditions. The pulsation intensity does not vary significantly, with the exception of one case where the amplitude is greater than for others by an order of magnitude. Numerical modeling of the ground based artificial emissions could solve the problem of their effective generation.
