Abstract
Solar wind observations associated with the enhanced levels of solar activity in August 1972 are reviewed with an emphasis on recent analyses which more unambiguously characterize the changes in the interplanetary medium. Observations from Pioneer 9 at ∼0.8 AU, Pioneer 10 at 2.2 AU, and in the vicinity of Earth are reviewed and reinterpreted in the light of new data. Recent calculations of local shock velocities are reviewed and their implications discussed. These results indicate that contrary to previously published observations there is no significant deceleration of the interplanetary shocks between 0.8 AU and 2.2 AU.
