SN 2004GT was a type Ic supernova that happened in the interacting galaxy NGC 4038 on December 12, 2004. The event occurred in a region of condensed matter in the western spiral arm.[2] The progenitor was either a type WC Wolf-Rayet star with less than 40 times the mass of the Sun, or a low-mass star in a binary star system.[3]
