Query: Solar Neutrino Results from Super-Kamiokande   Super-Kamiokande has measured the solar neutrino flux using elastic
neutrino-electron scattering in water. The measured flux is
$2.32\pm0.03$(stat)$^{+0.08}_{-0.07}$(syst)$\times10^6$/(cm$^2$s) based on the
energy range of 5 to 20 MeV for the recoiling electron. The time-dependence and
energy spectrum of the recoiling electrons were studied to search for
two-neutrino oscillation signatures. The absence of either significant zenith
angle flux variation or distortions of the recoil electron spectrum places
strong constraints on neutrino mass difference and mixing. In combination with
the flux measurement, two allowed regions at large mixing are found.
