  We perform an oscillation parameter-independent analysis of solar neutrino
flux measurements from which we predict the charged-current rate at SNO
relative to Standard Solar Model to be $R_{SNO}^{CC}=0.35^{+0.16}_{-0.09}
(0.46^{+0.13}_{-0.11})$ for oscillations to active (sterile) neutrinos. By
alternately considering the $^8$B flux normalization fixed and free, we find
that the flux measured by Super-Kamiokande (SK) not being a result of
oscillations is strongly disfavored for oscillations to active neutrinos. SNO
will determine the best-fit value of the $^8$B flux normalization $\beta$
(equal to the neutral-current rate), without recourse to neutral-current
measurements, from the derived relation $\beta=R_{SNO}^{NC}=5.85 R_{SK} - 4.85
R_{SNO}^{CC}$. Using a simple parameterization of the fraction of high,
intermediate, and low energy solar neutrinos starting above resonance, we
reproduce the results of global analyses to good accuracy; we find that the LMA
solution with a normal mass hierarchy is clearly favored. With $\beta$ free,
our analysis for oscillations to active neutrinos gives
$R_{SNO}^{NC}=\beta=1.34 \pm 0.34$, which corresponds to $R_{SNO}^{CC}=0.28\pm
0.07$.
