Photometric and interferometric observations of a mid-latitude stable auroral red arc
Abstract
Observational results of the mid-latitude stable auroral red arcs of October 30/31 and October 31/November 1, 1968 are presented. The measurements were made with a turret photometer and a 6 in. dia. high resolution, pressure scanning Fabry-Perot interferometer. The structure, intensity, and position of the red arc were determined from photometer scan measurements which show that the arc was stable, persisted for more than 12 hr, and moved southward during the night. The arc appeared to extend across the eastern part of the United States tilted to lines of constant magnetic L-shells. The results of the Doppler temperature measurements made with the Fabry-Perot interferometer show no measurable neutral gas temperature increase within the red arc.
