Observations of SAR arcs from OV1-10
Abstract
Three midlatitude red arcs were measured by the night airglow photometer on board OV1-10 (1966-111B) during the winter of 1966-1967. One arc was observed as a conjugate phenomenon. Another arc was observed for 2 days at a constant local time and was found to decrease in intensity, increase in width, and move to higher L values with universal time. Both arcs were found to be associated with the plasmapause, the location of which was determined from the VLF measurements made by OV3-3 (1966-70A). These observations are shown to be consistent with the theory that SAR arcs are generated at the plasmapause as a consequence of the turbulent dissipation of ring current energy.
