We are performing an all-sky search for the brightest supernova explosions. This will be the first systematic all-sky search for bright supernovae. The search uses the All-Sky Automated Survey, which has two 200-mm lenses with wide-field cameras in sites in Chile and Hawaii and is obtaining images of the entire sky every 1-3 days down to V~14 mag. The high cadence, large area, and magnitude limit of this survey are optimal for making early discoveries of 10-20 bright supernovae per year in nearby galaxies. This project will give us new insights into the progenitors of all supernova types, allow us to study supernovae in low-metallicity galaxies, and provide the first complete census and detailed characterization of the brightest supernovae in a volume-limited sample of galaxies.
