Li, Van Dyk, and Filippenko, together with J.-C. Cuillandre, Canada-France-Hawaii Telescope (CFHT) Corporation; and S. Jha, UCB, add: "We have confirmed our identification of the progenitor of SN 2005cs, using CFHT images taken on July 2.28 UT under excellent seeing conditions (0".7). Geometrical transformation between the CFHT images and the HST/ACS images (as mentioned above) yields a precision of 0.8 ACS pixel for the supernova location on the ACS images, and our proposed progenitor (above) is the only object within the error circle. The position of the progenitor is measured to be R.A. = 13h29m52s.760, Decl. = +47o10'36".11 (equinox 2000.0) on the mosaic F814W image. Since only one object exists within our error circle, and since the limiting absolute V magnitude in the ACS images is > about -3, we consider it highly suggestive that this red supergiant is the progenitor of SN 2005cs. Further analysis is in progress."
