Abstract : The drift velocities ranged from about 0.6 to 5-6 km/s, with a median speed estimated to be about 2 km/s. The drift effects of auroral ionization, lying inside the auroral zone, were considerably irregular, quite different from the regular character observed at latitudes between 50 and 60 degrees. In the time-interval between 22-02, and especially between 02-06 MET, the echoes were usually obtained from about 5-10 degrees farther east of north than during the rest of the day, during which the average distribution of the echoes seemed to be relatively constant. For some of the recordings obtained by means of the rotating antenna, a striking oscillation of the reflecting center was found. (Author)
