Abstract
A global two-neutrino oscillation fit combining Super-Kamiokande solar neutrino data with the solar neutrino rates measured by Homestake, Gallex/GNO, SAGE and SNO prefers a single allowed area, the Large Mixing Angle solution, at about 95% confidence level. The mass^2 difference between the two mass eigenstates is Delta m^2 approx 3-25 x 10^-5 eV^2, the mixing angle theta is tan^2 theta approx 0.21-0.67.
