I am adding this message, with links to some papers of interest from the New Journal of Physics. This is an "open access'" journal, or so they say, so anyone should be able to read the papers in html or PDF, without a subscription. The papers I will link to here are with reference to the standard solar models & the "solar neutrino problem".

Evidence for the MSW effect, Gianluigi Fogli and Eligio Lisi, October 25, 2004. The MSW effect is the neutrino oscillation mechanism. This paper reviews the observational evidence that this effect actually happens, and neutrinos do "oscillate".

Reactor neutrino oscillation studies with KamLAND, K. Inoue, October 28, 2004. This paper specifically reviews the observation of neutrino oscillations at the KamLAND reactor. This shows, along with the previous paper, that neutrino oscillations are not just somebody's theoretical "guess", and they are not just "observed" with solar neutrinos. Neutrino oscillations are observed in a laboratory setting, independent of solar neutrinos entirely.

Solar neutrinos, A.B. McDonald, September 23, 2004. A review of the current solar neutrino experiments.

My purpose here is to introduce some of the scientific literature which shows rather conclusively, that the "solar neutrino problem" is a solved problem, and that the real observation of neutrino oscillations is that solution. Also see Solar neutrinos: history from John Bahcall.
