Coronal isotopic abundances for the elements He, C, N, 0, Ne, and Mg are derived from previously published measurements of solar energetic particles by first measuring, and then correcting for the charge-to-mass-dependent fractionation due to solar flare acceleration and propagation processes. The resulting coronal composition generally agrees with that of other samples of solar system material, but the previously noted difference between the solar flare and solar wind ^(22)Ne/^(26)Ne ratios remains unresolved.
