The light curve of supernova 1987A is widely regarded as unusual, and perhaps anomalous. Using bolometric light curves, it is shown that the event is a natural intermediate case between supernovae of Types SNIa, SNIb, and bright SNII (SNII-L and SNII-P). An observational opportunity for the study of galactic evolution is mentioned.
