We present the detection of flares from the tidal disruption of stars by supermassive black holes in the Ultraviolet and Optical with GALEX and CFHTLS. The luminous UV/Optical flares, discovered in the nuclei of two otherwise quiescent early-type galaxies, have light curves that are well fitted by the canonical t-5/3 power-law decay predicted for emission from the fallback of debris from a tidally disrupted star. Chandra X-ray observations during the flares place tight constraints on their blackbody temperatures and peak bolometric luminosities. The luminosity, temperature, and light curve of the flares are in excellent agreement with emission from the tidal disruption of a main sequence star by black holes of a few times 107 solar masses. We use the observed properties of the flares to make predictions for the detection capabilities of the next generation of optical synoptic surveys: Pan-STARRS and LSST.
