Abstract

Voyager 1 is observing the energy spectra of anomalous cosmic ray H, He, and O in the heliosheath. The relative abundance of H/He is 20 at 1-1.5 MeV/nuc, indicating that H pickup ions are more efficiently accelerated than was modeled from observations at higher energies. Voyager 2 began observing upstream energetic ions from the shock in late 2004 at ∼75 AU, about 10 AU closer to the Sun than observed by Voyager 1. Voyager 2 will be at 84.7 AU at the end of 2007 and may have crossed the termination shock.
