THE ASSOCIATION BETWEEN RADIO AND VISUAL AURORA,
Abstract
Sections of the northern sky were scanned by radar and photometer at the Prince Albert Radar Lab. in central Saskatchewan, Canada, with its radar of 448-Mc/s frequency. Results demonstrated that there is often good spatial and temporal correlation between radio and visual aurora when (1) the visual aurora form is high enough in elevation angle so that the atmospheric extinction does not preclude its detection, (2) the lower atmosphere is clear of clouds and haze, and the background light from the moon and other sources is low for permitting observation of visual aurora, and (3) the aspect angle is close in orthogonality (low elevation angles in the direction of the magnetic north from Prince Albert) for permitting detection of radio auroral returns.
