Query: Uncertainties in the Solar Neutrino Flux   I discuss three issues relevant to solar neutrino flux measurements: cross
section uncertainties in pp chain reactions, uncertainties in the GALLEX/SAGE
response to 7Be and 51Cr neutrinos, and the implications of helioseismology for
nonstandard suns with mixed cores. A few comments are also offered on electron
neutrino to tauon neutrino oscillations, cosmologically interesting neutrino
masses, and recent proposals for supernova neutrino observatories.
