SN 1998bw was a rare broad-lined Type Ic[1] gamma ray burst supernova detected on 26 April 1998 in the ESO 184-G82 spiral galaxy, which some astronomers believe may be an example of a collapsar.[2] The supernova has been linked to GRB 980425, which was detected on 25 April 1998, the first time a gamma-ray burst has been linked to a supernova.[3] The supernova is approximately 140 million light years away, very close for a gamma ray burst source.[4]
