Superthermal Particles. The processes by which particles in cosmic plasmas are elevated in energy out of the ‘thermal’ regime and accelerated to very high relativistic energies has been a challenge to understand for decades. The Solar-Planetary-Relationship Section has organized a series of sessions around this theme, beginning with the upper atmosphere at the fringes of space and extending into the auroral regions, the effects of substorms, acceleration to high energy in the earth's radiation belts, and studies of the powerful effects of acceleration at Jupiter. Finally, sessions devoted to the high-energy particles in the solar wind, including cosmic rays, complete the span of energies in the ultrarelativistic region.
