A catalog of all supernovae discovered between 1885 and 1988 December 31 has been published by Barbon, Cappellaro & Turatto (1989). In Table 1 a similar listing is given for all 203 supernovae found between 1989 January 1 and 1993 April 1. A statistical discussion of these new data, and references to original sources, will be given in van den Bergh (1994). The main results of that paper are the following: (1) The most recently discovered supernovae, almost all of which were found during systematic search programs, show no evidence for the inclination effect. If no inclination corrections need to be applied then supernova rates in spirals are only half as large as previously believed (van den Bergh & Tammann 1989, Cappellaro et al. 1993). (2) The data for supernovae of type II (SNe II) show clear evidence for the Shaw (1979) effect. However, no evidence for such an effect (which is due to the fact that some supernovae are not discovered when they appear projected on the bright nuclear bulges of distant galaxies) is seen for the more luminous supernovae of Type Ia (SNe Ia). (3) Due to more intensive surveillance of bright galaxies supernovae with m (discovery) < 16 are frequently found before maximum light, whereas fainter supernovae are more often discovered at a later phase.
