T. Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 18.1) on unfiltered CCD images taken on Nov. 7.075 UT with a 0.35-m reflector. The new object is located at R.A. = 8:16:49.66, Decl. = +60:29:46.1 (equinox 2000.0), which is approximately 2".6 east and 11".2 north of the center of UGC 4294. Boles also measured position end figures 49s.63, 45".8 and magnitude V = 18.3 on Nov. 9.544 using an image (limiting mag 20.0) taken with the 0.61-m Cassegrain reflector at the Sierra Stars Observatory (Alpine County, California). Nothing is present at this position on Boles's images from 2010 Jan. 17 and Mar. 4 (limiting mag 19.5) or on Digitized Sky Survey plates from 1989 Dec. 21 (limiting red mag 20.5) and 1990 Jan. 1 (limiting blue mag 21.0).
