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.
