Query: Does the neutrino magnetic moment have an impact on solar neutrino
  physics?   Solar neutrino observations coupled with the recent KamLAND data suggest that
spin-flavor precession scenario does not play a major role in neutrino
propagation in the solar matter. We provide approximate analytical formulas and
numerical results to estimate the contribution of the spin-flavor precession,
if any, to the electron neutrino survival probability when the magnetic moment
and magnetic field combination is small.
