Abstract
Solar neutrinos from the decay of 8B have been detected at the Sudbury Neutrino Observatory (SNO) via the charged-current (CC) reaction on deuterium and the elastic scattering (ES) of electrons. The CC reaction is sensitive exclusively to electron neutrinos while the ES reaction also has a small sensitivity to muon and tau neutrinos. The flux of electron neutrinos from 8B decays measured by the CC reaction and ES reaction, assuming no flavour transformation, will be presented. These flux measurements provide evidence that there is a non-electron flavour active neutrino component in the solar flux. The total flux of active 8B neutrinos will be presented and shown to be in good agreement with predictions of solar models.
