Abstract: We present a new treatment of the Earth matter effects on the neutrinooscillations that is valid for an arbitrary density profile. When applied tothe the study of the day-night effect on the solar neutrino flux it renders usa simple analytical expression, which is more accurate than those derived byusing the perturbation theory and can be extended to higher energies.
