Abstract
The Fourier analysis of the measured 37Ar production rate for Davies' well known solar neutrino experiment shows time variations of the neutrino flux with periods of 100.0, 58.8, 35.7, 25.6, 19.6, 15.2, 8.8, and 6.3 months, respectively. We discuss physical assumptions of the standard solar model which are not generally confirmed by observations and trace back the time variations of the neutrino flux with the time scale of the order of years to gravity oscillations of the solar centre.
