Academy of Sciencies, 142190, Troitsk, Moscow region, Russia Abstract. We perform the rates-only analysis of the spin-flavour precession solutions to the solar neutrino problem using the data of the chlorine, gallium experiments, the SNO charge-current measurement, the 1258-day Super-Kamiokande data and the LSD upper limit on solar anti-neutrinos. In a self-consistent magneto-hydrodynamics approach there are only 3 effective parameters: Δm_2, μ_vB_⊥ and the neutrino mixing angle θ. We obtain the well-known resonant spin-flavor precession solution and find new non-resonant spin-flavor solution in the so called "dark-side" region. We show for fixed μ_vB_⊥ that spin-flavour precession solutions are slightly favours over oscillations.
