Graham and W. Li report the LOTOSS discovery of an apparent supernova on unfiltered KAIT images on July 1.5 (mag about 17.1) and July 2.5 UT (mag about 17.2). SN 2003gk is located at R.A. = 23h01m42s.99, Decl. = +2 16'08".7 (equinox 2000.0), which is 1".6 east and 19".2 north of the nucleus of NGC 7460. A KAIT image of the same field on 2002 Dec. 3.2 showed nothing at this position (limiting mag about 19.0). NOTE: These 'Central Bureau Electronic Telegrams' are intended to be preliminary announcements of items that later appear in the formal IAU Circulars.
