On the solar wind composition during the November 1997 solar particle events: WIND/MASS observations

November 1997 saw a series of very intense and unusual solar particle event s that have been well, studied [Cohen et al., 1999; Lario et al., 1998; Mas on et al., 1999; Mazur et al., 1999; Mobius et al., 1999]. However, the com position of the solar wind has not previously been analyzed. We report the elemental and charge-state composition of the solar wind during these event s. We find unusually broad and high charge-state distributions for O, Si, a nd Fe. Fe/O was enhanced by a factor > 3 - 5 relative to the ambient solar wind in the magnetic cloud and in the following material. We speculate whet her the observed compositional similarities in the solar wind and energetic particles might, in part, be explained by a common reservoir out of which both kinds of particles were accelerated.
