 SN       2011 UT        R.A. (2000.0) Decl.      Mag.      Offset
 2011cg   Apr. 14.33   14 59 09.25  + 7 18 04.2   15.7     2" W, 1" S

     G. H. Marion, Harvard-Smithsonian Center for Astrophysics (CfA), on
behalf of the CfA Supernova Group, report that a spectrum (range 340-740 nm)
of 2011cg was obtained on May 5 UT by P. Berlind with the F. L. Whipple
Observatory 1.5-m telescope (+ FAST).  Cross-correlation with a library of
supernova spectra using the "Supernova Identification" code (SNID; Blondin
and Tonry 2007, Ap.J. 666, 1024) shows that 2011cg is a type-Ia supernova
about two weeks after maximum light.
