The first results of the solar neutrino flux measurement from Super-Kamiokande are presented. The results shown here are obtained from data taken between 31 May 1996, and 23 June 1997. Using our measurement of recoil electrons with energies above 6.5 MeV, we infer the total flux of 8B solar neutrinos to be 2.42\ifmmode±\else\textpm\fi0.06(stat)_\ensuremath-0.07+0.10(syst)\ifmmode×\else\texttimes\fi106cm^\ensuremath-2s^\ensuremath-1. This result is consistent with the Kamiokande measurement and is 36% of the flux predicted by the BP95 solar model. The flux is also measured in 1.5 month subsets and shown to be consistent with a constant rate.
