Evidence for Anomalous Cosmic Ray Hydrogen


The period of solar minimum activity in 1987 provided the first evidence for the existence of anomalous cosmic ray (ACR) hydrogen (Christian et al. 1U88). More recent data from the Voyager 1 {Vl) and Voyager 2 (V2) spacecraft and subsequent improved analysis of earlier data serve to confirm the presence of ACR hydrogen. This paper will cover some of these new developments in the analysis.
