Scientific paper

A treatment is presented of the interpretive problem that emerges from the irreconcilability of the neutrinos detected by the Hirata et al. (1986) Kamiokande experiment and the Bionta et al. (1987) IMB experiment, which were suggested to be due to an initial core collapse to a neutron star, and the subsequent appearance of SN 1987a, at m(v) of 6.4 mag, only 11,000 sec later. The first detection of the SN and its subsequent luminosity and spectral evolution are, nevertheless, consistent with core collapse occurring about 5 hours earlier. The failure of Jones (as revealed in a private communication) to notice this SN only 1.25 hours before its first detection remains puzzling.
