Our current understanding of plasmaspheric hiss is that it is typically low-intensity and incoherent. Wave-particle interactions will lead to slow pitch angle diffusion or a slow drizzle particle precipitation. However the previous precepts are not totally correct. We will show that duskside plasmaspheric hiss with ~300 to 650 Hz frequencies can be both intense (~2.0 nT peak-to-peak) and coherent. Such waves can and will lead to very rapid particle losses for L < 6, or the subauroral duskside region. What are the sources of the waves and what particles and particle energies will be resonant with such waves? We will explore these topics in detail during the presentation.
