Chatanika Radar observations of ionospheric convection velocities spanning auroral latitudes (58/sup 0/-75/sup 0/..lambda..), and contours of electrostatic potential derived from them, are described for a period of moderately strong geomagnetic activity in the midnight sector. Digitized H component magnetograms and contours of magnetic perturbation, ..delta..H, derived from them are presented in order to compare the convection pattern and radar-deduced currents with the observed ground response to auroral electrojets. In spite of midnight sector substorm activity, the convection pattern maintains a two cell character. The latitude of greatest negative potential in the evening sector, determined from the radar data, accurately denotes the position of the Harang discontinuity in the ionospheric currents.
