Since the discovery of Supernova 1987A (A Type II supernova) in February of 1987 there has been a flurry of activity in the field of supernova modelling. The fact that the supernova occurred in the nearby Large Magellanic Cloud and that the progenitor star has almost universally been identified. Prior to exploding, SK -69 202 was seen as a B3-I blue supergiant with a surface temperature of approximately 16,000 K and a bolometric magnitude of 7.5 to -8.2. A blue supergiant becoming a Type II supernova shocked many people. It has been suggested that Sk -69 202 was once a red supergiant but it evolved back to the blue.
