The recent discovery of a supernova (SN 1998bw) seemingly associated with GRB 980425 adds a new twist to the decades-old debate over the origin of gamma-ray bursts. To investigate the possibility that some (or all) bursts are associated with supernovae, we performed a systematic search for temporal/angular correlations using catalogs of BATSE and BATSE/ Ulysses burst locations. We find no associations with any of the precise BATSE/ Ulysses locations, which allows us to conclude that the

This limit (1.5 used as a comparison data set (18 supernovae ≃ 20 associated gamma-ray bursts. Thus, although we find no significant evidence to support a burst/supernova association, the possibility cannot be excluded for weak bursts.
