SUPERNOVA 2011gd IN NGC 6186 = PSN J16342567+2132284
     Further to CBET 2772, S. B. Cenko, W. Li, and A. V. Filippenko report the
LOSS discovery of an apparent supernova on unfiltered KAIT images:

 SN       2011 UT        R.A. (2000.0) Decl.      Mag.      Offset
 2011gd   Aug. 28.16   16 34 25.67  +21 32 28.4   18.7    2".9 E, 0".9 N

This variable was designated PSN J16342567+2132284 when it was posted on the
Central Bureau's TOCP webpage and is here designated SN 2011gd based on the
spectroscopic report below.  Additional KAIT magnitudes for 2011gd:  a co-
added image from July 2011, [20.1; Sept. 3.15 UT, 17.5.

     J. M. Silverman, S. B. Cenko and A. V. Filippenko, University of
California, Berkeley, report that inspection of a CCD spectrum (range 340-1000
nm), obtained on Sept. 26 UT with the 10-m Keck I telescope (+ LRIS), shows
that PSN J16342567+2132284 = SN 2011gd is a significantly reddened, but
otherwise normal, type-Ib supernova.  The host-galaxy recession velocity, as
determined from narrow emission lines, is about 2800 km/s.
