Abstract:

Observations have been made of Lyman-alpha auroral emissions during January and February 1967. The observations were made with a narrow-band sky-scanning photometer mounted on an earth-oriented satellite in polar orbit. Auroras in the southern hemisphere were usually single in structure, and those in the north, complex. The single auroral emissions show a typical latitude spread of about 6.5 deg. Intensities up to 60 kR were observed at times of high magnetic activity, implying energy deposition up to 20 ergssq cmsec. The intensities show a correlation with high-latitude geomagnetic activity, with a breakdown during extremely active periods. Author
