Description
We present a revised version of "Sternberg Astronomical Institute Supernova Catalogue" which includes data on 930 extragalactic supernovae (SNe) discovered up to September 1, 1994 and the main data on their parent galaxies. The description of previous version was presented by Tsvetkov and Bartunov (1993). The main improvements are the following: 1. The RC3 catalogue (de Vaucouleurs et al., 1991) was used instead of the RC2 as main source of data for parent galaxies. 2. For recent supernovae we included some magnitudes at maximum light from Hamuy et al. (1993) and compared our data with those of van den Bergh (1993). We also corrected some velocities of galaxies according to Huchra et al. (1994). 3. Some galaxy identifications from the MCG ( M ) were replaced by the ones from the PGC and the UGC. The identifications were adopted with this order of preference: NGC (IC) - UGC (ESO) - MCG - PGC - others 4. Photographic magnitudes from the PGC ( marked '*' ) and from IAU circulars ( marked 'C' ) were used when no other data were available. 5. Some errors were found in the previous version, and many new identifications for the galaxies previously listed as "ANON" were adopted. 6. We included several precise astrometric positions of SNe from Porter (1993).
