SN 1988A in M58 - Departure from Co-56 decay 700 days after explosion
Observations of SN 1988A in M58 are presented which show a remarkable departure from Co-56 decay in the optical light curve starting about 700 days since explosion. It is shown that the departure cannot be explained by the contribution from other radioactive isotopes to the late luminosity, and fluorescence in nearby clouds can be excluded as the
