We explore in detail oscillations of the solar ⁸B neutrinos. We use approximate expressions for the matter effects in the Sun and in the Earth which are both accurate and have all advantages of a full analytic treatment. At night time we predict about 4.5% more registered electronic neutrinos (E_nu > 11MeV, about 80 registered neutrinos per day per 40kt ) at DUNE far detector than during day time. At night time the electronic neutrino regeneration is varied depending on azimuthal angle of the solar neutrino beam and neutrino energy. We underline the crucial role of the detector's energy resolution. Based on our analytic expressions we examine the possibility to look deep inside the Earth and measure the electron number densities at different layers of the Earth.
