✦ Synopsis

During periods in 1969-1971 when interplanetary flow conditions were quiet, 17 determinations of the solar wind Fe and Si abundances and 7 of the O abundance were made. On the average (N(Fe)/N(H))= 5.3 • 10 5, (N(Si)/N(H))=7.6 • 10 -5 and (N(O)/N(H)) = 5.2 • 10 -4. Variations from the averages over a total range of factors of ~4 for O, ~4 for Si, and ~ 10 for Fe have have observed. Although Fe and Si abundance variations appear to be correlated, no other element correlation pairs are unambiguously discernible from the present data set.
