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 
and 
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 
au, 
au, using a neutrino mass differences of 
meV, 
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.
