A statistical analysis of the pre-SNO solar neutrino data is made assuming the solar neutrino deficit to be resolved by the interaction of the neutrino magnetic moment with the solar magnetic field. Given the general characteristics of the field profiles known to lead to the best event rate predictions, several specific choices of profiles are assumed and fits to the rates, to the electron recoil spectrum in SuperKamiokande and to the combined rates and spectrum are performed. Both the rate and spectrum fits are remarkably better than in a previous analysis of the magnetic moment solution which used a former standard solar model and previous data, and in particular, rate fits are far better than those from oscillations. The global analysis also reflects the general very good quality of the fits.
