This article reports on a study of the characteristics of stable auroral red (SAR) arcs. These arcs are characterized by 6300-[angstrom] emission which normally appears near F region heights. In particular the authors study observations made in September, 1984. These studies showed that oxygen ion collisions in the ring current were responsible for the recovery phase enhancement of the SAR. Satellite observations showed and enhanced 15 to 25 keV proton component in the ring current during the main phase of the SAR which is responsible for the enhancement during this phase of the event. This enhanced high energy proton flux appears to have come from ion injection into the inner magnetosphere in response to an abrupt change in the electric field across the magnetotail.
