  The Sudbury Neutrino Observatory (SNO) is a water imaging Cherenkov detector.
Its usage of 1000 metric tons of D$_{2}$O as target allows the SNO detector to
make a solar-model independent test of the neutrino oscillation hypothesis by
simultaneously measuring the solar $\nu_{e}$ flux and the total flux of all
active neutrino species. Solar neutrinos from the decay of $^{8}$B have been
detected at SNO by the charged-current (CC) interaction on the deuteron and by
the elastic scattering (ES) of electrons. While the CC reaction is sensitive
exclusively to $\nu_{e}$, the ES reaction also has a small sensitivity to
$\nu_{\mu}$ and $\nu_{\tau}$. In this paper, recent solar neutrino results from
the SNO experiment are presented. It is demonstrated that the solar flux from
$^{8}$B decay as measured from the ES reaction rate under the no-oscillation
assumption is consistent with the high precision ES measurement by the
Super-Kamiokande experiment. The $\nu_{e}$ flux deduced from the CC reaction
rate in SNO differs from the Super-Kamiokande ES results by 3.3$sigma$. This is
evidence for an active neutrino component, in additional to $\nu_{e}$, in the
solar neutrino flux. These results also allow the first experimental
determination of the total active $^{8}$B neutrino flux from the Sun, and is
found to be in good agreement with solar model predictions.
