We consider whether the observed fractionation of Ne isotopes recently reported in solar energetic particle (SEP) events is due to the same charge-to-mass dependent fractionation processes that apparently cause SEP elemental composition variations. We find that the observed correlation of the 22Ne/20Ne and Na/Mg ratios in nine large SEP events is consistent with a common fractionation process if the charge states of these ions are characteristic of a source temperature of -1.5 to -4 million degrees.
