Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 17.4) on unfiltered CCD images taken on Sept. 23.892 and 24.812 UT with a 0.35-m reflector. The new object is located at R.A. = 18h53m38s.48, Decl. = +66o13'59".3 (equinox 2000.0), which is approximately 12".1 east and 3".4 north of the center of the apparent host galaxy. Nothing is present at this location on Boles' images from May 17 and July 17 (limiting mag 19.5) or on Digitized Sky Survey images from 1991 Aug. 31 (limiting red mag 21.0) and 1992 June 29 (limiting blue mag 20.5).
