N2 - The radiative neutrino decay in the mass and a lifetime range, mv=10-100 keV and τv=103-105 s, is often argued to be forbid by γ-ray data from past supernovas. We demonstrate that this argument is not always correct, and accordingly attempt to explain via radiative neutrino decay the unusual soft component of the X-ray spectrum from SN 1987A, observed by the satellite Ginga. Our fit to the data suggests that τv=(1-3)×104s·(mv/50 keV).
