magnetic field, etc.) to great accuracy, but has one major problem; the number of neutrinos we actually observe emenating from the Sun is approximately 1/3 that which we expect from the SSM. This is what is known as the Solar Neutrino Problem, or SNP.
Solar Neutrino Problem
As shown in the animation describing the proton-proton chain above, the number of neutrinos produced in the Sun is directly proportional to the number of nuclear reactions that are taking place in the Sun's core.
solar neutrino problem The discrepancy between the theoretically predicted numbers of neutrinos streaming from the Sun as a result of fusion reactions in the core and the numbers actually observed.
Solar neutrino problem
For many years the number of solar electron neutrinos detected on Earth was one third to one half of the number predicted by the standard solar model. This anomalous result was termed the solar neutrino problem.

It was the chlorine detector in Homestake, South Dakota, containing 520 tons of fluid, which first detected the deficit of neutrinos from the sun that led to the solar neutrino problem. This type of detector is only sensitive to νe.

It was the chlorine detector in the former Homestake Mine near Lead, South Dakota, containing 520 short tons (470 metric tons) of fluid, which first detected the deficit of neutrinos from the sun that led to the solar neutrino problem.
