Abstract
There have been an increasing number of candidates for the gamma-ray bursts /supernovae connection. Among these, the Type Ic SN 1998bw and the Type IIn SN 1997cy are characterized by their extremely large explosion energy, wel l in excess of 10(52) erg, and thus have been called hypernovae. Here we su ggest that the peculiar Type Ic SN 1997ef is another hypernova.
