Abstract
From 2001 to 2002 the anomalous cosmic ray (ACR) He intensity at 52 MeV/nuc increased by a factor of ∼2.2 at Voyager 1. The increase was larger at lower energies, indicating that Voyager 1 was 7.5±2.2 AU closer to the termination shock in 2002. Since Voyager 1 moved outward 3.8 AU during this time, it appears the shock moved inward 3.7±2.2 AU following short term transient motions outward during solar maximum.
