Abstract

This paper describes the solar wind plasma ejected by the proton flares of August/September, 1966, in McMath Region 8461. The discussion will serve a dual purpose. First it will help complete the record on the events of August/September 1966. Secondly we will discuss the helium enrichment of the interplanetary plasma associated with the flares. This is the fifth case reported in which major flares produce helium enriched interplanetary plasma. Relative helium abundances of greater than 15% are typical. These findings are interpreted in terms of a solar atmosphere that contains helium enriched regions.
