Solar neutrinos, solar flares, solar activity cycle and the proton decay

It is shown that there may be a correlation between the galactic cosmic ray and the solar neutrino data. But it appears that the neutrino flux, which may be generated during the large solar cosmic ray events, cannot in any way effect the solar neutrino data in the Davis experiment. Only an initial stage of mixing between the solar core and solar outer layers after the sunspot maximum in the solar activity cycle can explain the higher (run number 27 and 71) solar neutrino data in the Davis experiment. But solar flare induced atmospheric neutrino flux may have an effect in the nucleon decay detector underground. The neutrino flux from solar cosmic rays may be a useful guide to understand the background of nucleon decay, magnetic monopole search, and the detection of neutrino flux in seawater experiments
