The asymmetric propagation through the solar wind of shocks from solar eruptions influences the dynamics of the outer heliosphere. In 2002, these effects - and not the crossing of the termination shock (TS) - may have been responsible for the differences in observations made by Voyager 1 (V1) at 85 AU, 34° North and Voyager 2 (V2) at ~67 AU, 24° South. We suggest these observations stemmed from two series of solar eruptions that propagated asymmetrically in longitude and primarily to the south. At V1 this led to unusually weak magnetic fields and increased access to particles from two sources: the TS and particles accelerated at the shocks created by the second series of solar eruptions as they propagated outward, passing V2. Because V1 was farther out, these particles showed anisotropies from an interior source. We used the HAFv2 model to study the propagation of the solar events. It predicted: 1) the 1 August 2002 shock observed on V2; 2) the trends in the V2 plasma and magnetic field data in August 2002; and implied 3) an extended period of increased particle transport near V1 in 2002. We estimate that on August 1, 2002 the termination shock was at ~ 121 AU.
