| Summary: | Abstract. This article is dedicated to one of the actively developing line of investigation in space plasma physics such as artificial modification of the ionosphere. Experiments carried out using Tromso heating facility with pump wave frequency of transmitter 4.04 MHz with square modulation period 10 minutes in 16 February 2003 is considered. This event was selected because of orbits projections of CLUSTER satellites along magnetic field lines went nearby disturbed region in ionosphere according to Tsyganeko model (T96). Electric, magnetic field and electron density data from CLUSTER satellites and IRIS imaging riometer data using wavelet, short time Fourier transform and spectral time analysis developed in IZMIRAN are analyzed. It is shown that effect is clearly observed in IRIS imaging riometer data (16 February 2003) right in the beam where the heating spot is. Also effect of heating is observed in CLUSTER data when satellites cross magnetic field lines conjugated with disturbed region. Thus it is experimentally shown that functioning of heating facility affects not only ionosphere but also the coupled ionospheric-magnetospheric interaction system. |
