Abstract—We describe the Sternberg Astronomical Institute (SAI)catalog of supernovae. We show
that the radial distributions of type-Ia, type-Ibc, and type-II supernovae differ in the central parts of
spiral galaxies and are similar in their outer regions, while the radial distribution of type-Ia supernovae in
elliptical galaxies differs from that in spiral and lenticular galaxies. We give a list of the supernovae that are
farthest from the galactic centers, estimate their relative explosion rate, and discuss their possible origins.
