There are two important points that are worth noting from this study and this article. It has been known for a while now that radiometric decay seems to be affected by solar flares and solar variation, and indeed that does seem to track with the results from Super-K, meaning that the variations are likely related to neutrino variations. It does suggest that this is a viable method of neutrino detection.In examining the radioactive decay fluctuations, the team found evidence that those fluctuations matched patterns they had found in Super-Kamiokande neutrino data, each indicating a one-month oscillation attributable to solar rotation. The likely conclusion is that neutrinos from the sun are directly affecting beta-decays. This connection has been theorized by other researchers dating back 25 years, but the Sturrock-Fischbach-Scargle analysis adds the strongest evidence yet. If this relationship holds, a revolution in neutrino research could be underway.
The other point that's noteworthy is the fact that neutrino output from the sun is variable to start with, and variable based on the *rotation* pattern of the surface of the sun. That variation with rotation would suggest that at least *some* of the neutrino output is associated with solar flares, and coronal loop activity, and some fusion likely takes place in the upper solar atmosphere, just as EU/PC theory predicts, not just inside of the core of the sun. If that were not true, the rotation cycle of the sun would be irrelevant and neutrino output would not be in any way related to the solar surface rotation cycle.
