SUPERNOVA 2010ki
     S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata) of an apparent supernova (mag 16.9) on unfiltered CCD
frames taken on Dec. 2.473 UT using a 0.60-m f/5.7 reflector (limiting
magnitude 19.0).  The new object is located at R.A. = 23h16m09s.58 +/- 0s.02,
Decl. = -2d14'05".3 +/- 0".3 (equinox 2000.0), which is 5".4 west and 5".2
south of the center of the presumed host galaxy, 2MASX J23160991-0214004.
Nothing is visible at this position on the Digitized Sky Survey (no
limiting-magnitude information provided).  Additional unfiltered CCD
magnitudes for 2010ki:  2006 Aug. 3.63, [19.5 (Itagaki); 2010 Nov. 21.447,
17.3 (Itagaki; pre-discovery; 0.50-m f/6 reflector); Dec. 3.062, 16.3 (T.
Yusa, Osaki, Japan, remotely using a 0.25-m f/3.4 hyperbolic astrograph +
SBIG ST-10XME camera at the RAS Observatory near Mayhill, NM, U.S.A.; position
end figures 09s.58, 06".1; offset 4".5 west, 5".3 south).  Itagaki has posted
