Boles, Coddenham, England, reports the discovery of an apparent supernova (mag 17.6) on 12 unfiltered CCD images taken on Aug. 20.880 and 22.006 UT with a 0.35-m reflector. The new object is located at R.A. = 17h19m35s.27 +/- 0s.15, Decl. = +86o44'30".5 +/- 0".1 (equinox 2000.0), which is approximately 4".4 east and 12".2 north of the center of UGC 10923. Nothing is present at this position on Boles' images from 2008 Feb. 10 and 2009 Aug. 9 (limiting mag 19.5) or on Digitized Sky Survey plates from 1996 Aug. 5 (limiting red mag 21.0) and 1998 May 31 (limiting blue mag 20.5).
