Auroral heights have been measured by a new method employing a pair of image orthicon television cameras placed at the ends of 10-km baseline. The instrumental configuration permitted auroral height measurements with a spatial resolution of 1 millirad and time resolution of 1/30 sec. Reduction of data gathered by the technique has been done by locating image pairs on the star background and using a computer program to determine the altitude of the auroral lower border. Some typical measurement results are presented for three types of auroral forms: pulsating forms, rayed forms, and post-breakup homogeneous forms. With few exceptions, all pulsating auroral borders were in the range 82-105 km with a median altitude of 92 km. Primary electron energy near 30 keV is required to reach 92 km, and energy near 60 keV is required to produce the lowest border observed, 83 km.
