discovery of an apparent supernova on unfiltered KAIT images taken
on Feb. 4.50 (at mag 18.0) and 5.56 UT (mag 18.2).  SN 2005ac is
located at R.A. = 13h39m55s.82, Decl. = +0o52'15".0 (equinox 2000.0),

object at mag about 18.5, while an image taken on 2004 June 20.21
showed nothing at this position (limiting mag 19.5).
