  • In-situ observed electron spectrum and hard X-ray photon spectrum correlation:
    • Explore why there is no agreement with the prediction of the thick-target model (Brown, 1971) that would be expected for footpoint emission.
  • Arrival time of ions at 1 AU suggest a delayed release of the ions relative to the electrons (Wang et al., 2005), is this due to:
    • Different accelerators for electrons and ions or
    • Propagation effects (turbulence, diffusion, magnetic connectivity)?


Required observations:


  • Several hours.

Other constraints:

  • Perihelion.
