solar neutrinos

For those who haven't already heard, the first results from the Sudbury
Neutrino Observatory were released yesterday. Comparing their results
to those from Super-Kamiokande, they find a 3.3-sigma difference between
the charged-current neutrino flux (sensitive only to nu_e) and the
elastic scattering flux (which is also somewhat sensitive to the other
flavors). The difference is presumably due to oscillation of electron
neutrinos into another flavor. The inferred total neutrino flux is
completely consistent with solar models.
