Abstract
Simultaneous measurements of the 5577A line and the 3914A line in the aurorae are described. The measurements were made with a scanning photoelectric photometer. The 3914A line was present toward the north during the entire period of observation. The 3914A line usually showed a larger increase relative to the night-sky background than did the 5577A line. In a pulsating aurora, the 3914A line showed many small pulsations, whose period was 1 to 2 seconds, in addition to the large pulsations.
