By combining data from the Stare auroral radar system and the Triad satellite, it has been possible to study the nature of field-aligned current closure in the vicinity of the Harang discontinuity. For the 2 days studied the largest electric fields were directed predominantly in the north/south directions, and field-aligned current closure was via north/south directed Pedersen currents. The concurrent electrojets were overlapping east/west directed Hall currents with the westward electrojet to the north. From the Stare-Triad data, latitudinal profiles of the ionospheric Joule heating rate and the height-integrated Pedersen conductivity have been calculated. The Joule heating rate maximized to the north and south of an auroral arc and had peak values of 2--4 mW/m2. The height-integrated Pedersen conductivity outside of the auroral arc was approximately 4&OHgr;-1, whereas in the vicinity of the arc, it was in excess of 12&OHgr;-1. These values are in good agreement with incoherent scatter and rocket measurements. The agreement is gratifying, since our technique for the calculation of the Pedersen conductivity does not require a model of the altitude-dependent collision frequency.
