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-Mcs 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.
