Nakano, Sumoto, Japan, reports the discovery by K. Itagaki (Teppo-cho, Yamagata, Japan, 0.60-m f/5.7 reflector) of an apparent supernova (mag 15.3) on unfiltered CCD exposures taken around Nov. 8.82 and 9.81 UT; the new object is located at R.A. = 12h43m40s.74, Decl. = +16d23'14.1 (equinox 2000.0), which is 27" west and 22".5 south of the center of NGC 4651. Nothing is visible at this location on the Digitized Sky Survey or on Itagaki's many past CCD frames, including those taken on Feb. 24 (limiting mag 19.5) and June 28 (limiting mag 19.0).
