California Institute of Technology; E. C. Beshore and S. M. Larson, Lunar and
Planetary Laboratory, University of Arizona; and E. Christensen, Gemini
Observatory, report the discovery of an apparent supernova detected in
multiple sequences of unfiltered CCD exposures of the Catalina Sky Survey
(CSS) using the 0.7-m f/1.9 Catalina Schmidt telescope (+ 4000x4000 camera):

 SN       2008 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2000cg   May  5.39   15 54 15.15  +10 58 25.0   16.7    2".4 W, 15".0 N

Additional CSS magnitudes for 2008cg:  Mar. 4.45 UT, [19.5; 31.35, 17.6;
Apr. 7.51, 16.9; 13.40, 16.8; 28.45 16.6.  This object is not seen in prior
Sloan Digital Sky Survey (SDSS) and Palomar-Quest co-added images to a
limiting magnitude of approximately 21.5.  The host galaxy (FGC 1965) has z
= 0.036 (Giovanelli et al. 1997, A.J. 114, 122; via NED) and SDSS magnitudes
g = 17.4, r = 16.8, and i = 16.4.  Specific details and links to discovery
