3. Ring Current Energization and Loss

STORM will help us understand the sources and losses of the ring current particles in the inner magnetosphere.

  • FUV and ASI define magnetotail mode.
  • ENA observes injections, ring current variations, dawn/dusk intensities to infer magnetopause loss and neutrals produced by charge exchange.
  • XRI observes magnetopause location.
  • FUV observes precipitation-driven proton aurora 
Ring current intensities diminish rapidly via magnetopause outflow during storms
