Abstract

Intensity of the auroral radiation from the entire sky as a function of time was monitored photoelectrically at College, Alaska. Measurements extended over two years. Very good correlation was found between the 3914A band of N2+ and the 5577A line of OI. An intensity-time curve of a typical auroral display is shown. A diurnal variation curve is obtained which is very consistent, giving the same form for weak, moderate, and strong aurorae, and showing no evidence of seasonal variation. A rapid fluctuation in the intensity of radiation is reported.
