SUPERNOVA 2010kx IN NGC 7645
     S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata) of an apparent supernova (mag 17.5) on unfiltered CCD
frames (limiting magnitude 18.5) taken on Dec. 19.383 (0.50-m f/6 reflector)
and 20.360 UT (0.60-m f/5.7 reflector).  The new object is located at R.A. =
23h23m46s.37, Decl. = -29d23'10".0 (equinox 2000.0), which is 11".1 west and
3".3 north of the center of NGC 7645.  Nothing is visible at this position on
his many past frames, including one taken on 2009 Oct. 19.51 (limiting mag
19.0) and another on 2010 Dec. 8.41 (limiting mag 18.0) or on the Digitized
Sky Survey.  Itagaki has posted his images at the following website URL:
