It is shown that the experiments on solar neutrinos can be accounted in terms of the Mikheyev-Smirnov-Wolfestein theory with DELTAm2 = 6 x 10(-6) eV2 and sin2 2theta = 7 X 10(-3). In the scenario proposed here the high energy neutrinos, from B-8, have a survival probability around 1/3, the intermediate ones, around the Be-7 line a very small one approximately 2 x 10(-3) axid the low energy neutrinos, the ones coming from pp reactions, do not oscillate.
