A large fraction of the magnetospheric wave energy from lightning discharges propagates in the nonducted (oblique) mode and is often found to multiply (up to 8-10 bounces) reflect back and forth between hemispheres (Edgar, 1976). The reflections occur where the wave frequency matches the local lower hybrid frequency, leading to the so-called Magnetospherically Reflected (MR) whistlers as observed on a spacecraft. Magnetospherically reflected whistlers resonantly interact with energetic (of order 100 keV) electrons in a relatively narrow energy range during multiple equatorial crossings over a wide range of L-shells (1.5 < L < 4). Results indicate that wave energy that enters the magnetosphere at a fixed location can potentially contribute to the loss of particles over a wide range of latitudes.
