New Horizons observed the unexplored, distant Jovian magnetotail to > 2500 RJ. A high-temperature,
multi-species population of energetic particles is characteristic of regions closer to the planet. Velocity
dispersions, anisotropies, and compositional variation seen in the deep-tail (> ~500 RJ) with a ~3-
day periodicity suggest similar events that were observed at ~100 RJ in Galileo data. The signatures
suggest plasma streaming away from the planet and injection sites in the near-tail region (~200 to 400
RJ) that could be related to magnetic reconnection events. The observed tail structure remains coherent at
least as far as the first outbound crossing into the magnetosheath. Preliminary estimates suggest that this hot
plasma population is sufficient to balance the pressure of the interplanetary magnetic field to this distance,
maintaining the magnetotail structure.
