Status of the MSW Solutions to the Solar Neutrino Problem
  In this talk we present the results of an updated global analysis of two-flavor MSW solutions to the solar neutrino problem in terms of conversions of $\nu_e$ into active or sterile neutrinos including the the full data set corresponding to the 825-day Super-Kamiokande data sample as well as to Chlorine, GALLEX and SAGE experiments.
