2004CBET...74....1N

S. Nakano, Sumoto, Japan, reports the discovery by K. Itagaki, Teppo-cho, Yamagata, Japan, of a bright supernova on at least ten CCD frames taken around July 31.76 UT using a 0.60-m f/7 reflector. The object is located at R.A. = 7h37m17s.02, Decl. = +65o35'57".8 (equinox 2000.0), which is roughly 160" east and 10" north of the nucleus of NGC 2403. The unfiltered (roughly V) mag was 11.2. Itagaki confirmed the object on Aug. 1.45, when it was estimated at mag 11.3. Nothing was visible at the object's location on Itagaki's numerous earlier CCD frames; specifically, it was not present to limiting mag 18.5 on 2002 Sept. 19 and Oct. 11.
