Abstract

We perform a model-independent analysis of solar neutrino flux rates including the recent charged-current measurement at the Sudbury Neutrino Observatory (SNO). We derive a universal sum rule involving SNO and SuperKamiokande rates, and show that the SNO neutral-current measurement cannot fix the fraction of solar

ν_{e}

oscillating to sterile neutrinos. The large uncertainty in the standard solar model

^{8} B

flux impedes a determination of the sterile neutrino fraction.
