Present status of solar and atmospheric neutrinos

The results from Super-Kamiokande on atmospheric neutrinos and solar neutrinos are presented. The analyses of atmospheric neutrinos using fully contained and partially contained events, upward-through-going muons, and upward-stopping muons, all show evidence for nu(mu) oscillations. The obtained, neutrino oscillation parameters are Delta m(2) of 10(-3) - 10(-2) eV(2) and sin(2) 2 theta > 0.8. The observed solar neutrino flux is 47 % of the expectation from the standard solar model. No sinificant day/night difference is observed and a solar model independent limit on neutrino oscillation parameters is obtained. The spectral shape comparison of the recoil electrons between the data and the expectation gives 4.8 % confidence level.
