We make a global vacuum neutrino oscillation analysis of solar neutrino data,
including the seasonal and energy dependence of the recent Super-Kamiokande
708-day results. The best fit parameters for \nu_e oscillations to an active
neutrino are \delta m^2 = 4.42\times10^{-10} eV^2, \sin^2 2\theta = 0.93. The
allowed mixing angle region is consistent with bi-maximal mixing of three
neutrinos. Oscillations to a sterile neutrino are disfavored. Allowing an
enhanced hep neutrino flux does not significantly alter the oscillation
parameters.Comment: Latex2.09, 10 pages, uses epsf.sty, 3 postscript figure
