Abstract : The Brazil Ionospheric Modification Experiments (BIME) provided an opportunity to conduct simultaneous airglow and electron content observations during a space plasma active experiments campaign in Natal, Brazil, in September 1982. A period of background data was also obtained, and computer simulation studies were conducted for the background and artificially disturbed conditions. The BIME -1 release produced a depletion in TEC of 1-1.5 TEC units that was accompanied by an airglow burst of approximately 500 R at 6300 A. Wide-angle imaging at 6300 A revealed an airglow cloud that extended to 150 km in radius. Postmission simulation studies carried out using the Boston University Finite Element Simulation (FES) Code were in good agreement with the observations. (Author)
