The event occurred in a region of condensed matter in the western spiral arm. The progenitor was not identified from older images of the galaxy, and is either a type WC Wolf-Rayet star with a mass over 40 times that of the Sun, or a star 20 to 40 times as massive as the Sun in a binary star system.[5] References1. ^1 {{citation | display-authors=1 | last1=Modjaz, M. | last2=Blondin, S. | last3=Kirshner, R.
