SUPERNOVA 2004dj IN NGC 2403
     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.
