Abstract. We calculate the absorption probability of photons radiated from the surface of the Sun by a left-handed neutrino with definite mass and a typical momentum for which we choose |p1| = 0.2 MeV, producing a heavier right-handed antineutrino. Considering the two transitions $\nu_1 \to \nu_2$ and $\nu_2 \to \nu_3$ we obtain the two oscillation lengths L 12 = 4960.8 m, L 23 = 198.4 m, the two absorption probabilities P 12 abs. = 2.5 x 10-67, P 23 abs. = 1.2 x 10-58 and the two absorption ranges $R_{12}^{\mathrm {abs.}} = 4.47\times 10^4 \;R_{\odot} = 208.0$ au, $R_{23}^{\mathrm {abs.}} = 0.89\times 10^4 \;R_{\odot} = 41.4$ au, using a neutrino mass differences of $\sqrt{\vert\Delta m^2_{12}\vert} = 10$ meV, $\sqrt{\vert\Delta m^2_{23}\vert} = 50$ meV and associated transition dipole moments. We collect all necessary theoretical ingredients, i.e. neutrino mass and mixing scheme, induced electromagnetic transition dipole moments, quadratic charged lepton mass asymmetries and their interdependence.
