Abstract
We here discuss the possibility that the peculiar supernova SN 1998bw and t he Gamma-Ray Burst GRB 980425 are associated. If the two are related, the e nergy radiated in gamma rays is at least four orders of magnitude less than in other GRBs, although its appearance is otherwise unremarkable: this sug gests that very different mechanisms may give rise to GRBs.
