We here discuss the possibility that the peculiar supernova SN1998bw and the Gamma-Ray Burst GRB 980425 are associated. If the two are related, the energy radiated in rays is at least four orders of magnitude less than in other GRBs, although its appearance is otherwise unremarkable: this suggests that very different mechanisms may give rise to GRBs.
Key words: gamma-rays: bursts -- (stars:) supernovae: individual: SN1998bw
