Abstract
The latitudinal component of the ionospheric current distribution has been calculated for three isolated substorms during the ionosphere modification by SW heating in Troms phi, Norway. The specific features of the auroral we stward electrojet behavior have been determined in connection with the oper ation of transmitters: electrojet maximum displacement and fixation of the electrojet equatorward boundary. The current calculation results have been corroborated by a comparison with the observations of auroras.
