Abstract:
    We conducted an optical CCD search for supernovae in a sample of 142
    bright [m(B)<=16mag], nearby (z<=0.03) starburst galaxies over the
    period 1988 December to 1991 June, to a limiting R-band magnitude of
    18. Five supernovae were found, in all cases outside the host galaxy's
    nucleus. We determine supernova rates (in supernova units or SNU) in
    the extranuclear regions to be 0.7h^2^SNU for Type Ia, 0.7h^2^SNU
    for Type Ib/c, and 0.6h^2^SNU for Type II, with large uncertainties
    but upper limits of 2.2h^2^, 2.5h^2^, and 1.7h^2^SNU, respectively.
    These rates are similar to those measured in "normal" galaxies. We
    found no evidence for a supernova-induced brightening in any galactic
    nucleus and, with a few reasonable assumptions, can place upper limits
    of 9h^2^, 12h^2^, and 7h^2^SNU on the rates of unobscured supernovae
    Types Ia, Ib/c, and II, respectively, inside the nuclei.
