Mondol, University of Texas, report the discovery of an apparent supernova (mag about 17.6) in unfiltered CCD images taken on Nov. 30.51 and Dec. 1.49 UT with the 0.45-m ROTSE-IIIb telescope at the McDonald Observatory; the new object was found by subtracting a co-addition of images taken between 2004 Dec. 15 and 2005 Jan. 16 (limiting mag about 19.0). SN 2005la is located at R.A. = 12h52m15s.68, Decl. = +27o31'52".5 (equinox 2000.0; uncertainty +/- 0".8), which is 6" west and 6" south of the center of the galaxy KUG 1249+278.
