Super-Kamiokande's Solar Neutrino Results

Results from solar neutrino measurements at Super-Kamiokande(SK) are presented. Precise measurements of the day/night difference and the energy spectrum obtained by 1496 days' SK-I data indicate that the neutrino oscillation parameters are in the LMA region with a constraint of the total flux. The energy spectrum upturn which is expected at the best fit oscillation parameters obtained by global analyses is not observed yet. SK-II has been taking data since December 2002. Preliminary results from SK-II are consistent with that from SK-I. Future prospects of solar neutrino measurements at SK are also discussed.
