From the results of the Homestake Cl experiment the anticorrelation is known to take place between the solar neutrino flux and the solar activity, in particular, the solar flares. The Cl detector has a threshold neutrino energy of 0.8 MeV. An attempt was made by the authors to analyze the relationship between the flare activity and the neutrino flux detected in Gallium Experiment (GALLEX). Gallium detector has a threshold neutrino energy of 0.2 MeV. The flare activity was found to be the many-valued function of the neutrino flux provided that the neutrino flux was taken to be about one solar rotation ahead of the flare activity. It should be noted that it was precisely this many-valuation that did not allow us to reveal clear relationship between the neutrino flux and the flare activity in preliminary analysis. Some possible mechanisms are discussed which can lead to these effects.
