The All-Sky Automated Survey for Supernovae (ASAS-SN)

The goal of ASAS-SN is to monitor the entire visible sky on a nightly basis for bright transients. ASAS-SN will reach this goal by the end of 2017. In the interim, ASAS-SN already dominates the discovery of bright supernovae (<17 mag) with significantly fewer biases than previous surveys. Along the way, ASAS-SN has found most of the well-studied tidal disruption events, the most luminous supernova found to date, and interesting "changing-look" AGN. ASAS-SN also now finds the majority of Galactic novae, huge numbers of outbursts from cataclysmic variables, and extreme flares from M and even L dwarf stars. ASAS-SN has also identified some 70,000 new variable stars and provides a simple WWW interface that will supply an up to the moment light curve for any user-selected point on the celestial sphere. With an all-sky sensitivity reaching low surface brightnesses, ASAS-SN can also be used to search for light echoes from historical transients and low surface brightness structures around massive galaxies or low surface brightness dwarf galaxies.
