✦ Synopsis

The recent results from the solar neutrino observation in Super-Kamiokande is presented. From the 504 days of data, taken between the 31st of May, 1996 and the 25th of March, 1998, we have obtained the SB-solar neutrino flux ratio to the prediction of the standard solar model of BP98 to be n ATA +0.010 +0.017 (tl ~. 13 r'+0 0L1 +0.018 for ~'~'~--0.009 --0.014 ~'O~O--0.010--0.015 TC98). We found no significant difference between day and nighttime flux. The spectrum shape is compared with the expected fi'om the SB neutrino spectrum, the neutrino interaction and the detector response, and we haw~ obtained X 2 of 25.3 (15 d.o.f), corresponding to a 4.6% C.L. hnplications of these measurements to neutrino oscillations are discussed.
