Confronting Spin Flavor Solutions of the Solar Neutrino Problem with   current and future solar neutrino data
  We show that spin flavor precession solutions to the solar neutrino problem, although preferred by the latest solar data, are ruled out by the first results from the KamLAND reactor experiment, at more than 3_sigma. An illustrative chi2 plot comparing these descriptions with oscillations is given.
