Abstract:

Three mid-latitude red arcs were measured by the night airglow photometer on board the OV1-10 1966-111B satellite during the winter of 1966-1967. One arc was observed as a conjugate phenomenon. Another arc was observed for two 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 of these arcs were found to be associated with the plasmapause, the location of which was determined from the VLF measurements made from the OV3-3 1966-70A satellite. 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. Author
