Trimpi events on low latitude paths - An investigation of gyroresonance interactions at low L-values
Abstract
Trimpi events observed at Durban (L = 1.69, 29 deg 53 min S, 31 deg 00 min E) are reported, and the efficacy of gyroresonance scattering in precipitating electrons into the atmosphere at low L (less than 2) is investigated. Utilizing the full relativistic equations of motion, a test particle simulation is used to determine the region in parameter space where large pitch angle scattering occurs. It is found that at low L the conditions for pitch angle scattering are less favorable than at higher L (L of about 4).
