     S. Howerton, Arkansas City, KS, USA; A. J. Drake, S. G. Djorgovski, A.
Mahabal, M. J. Graham, and R. Williams, California Institute of Technology;
J. L. Prieto, Carnegie Observatories; M. Catelan, Pontificia Universidad
Catolica de Chile; R. H. McNaught and G. Garradd, Australian National
University; E. C. Beshore and S. M. Larson, Lunar and Planetary Laboratory,
University of Arizona; and E. Christensen, Gemini Observatory, reported the
Catalina Real-time Transient Survey discovery of an apparent supernova in
public images from the Catalina Sky Survey (CSS):

 SN       2011 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2011ki   June 1.34   16 10 30.55  +27 30 00.5   19.0    6".9 W, 3".0 N

The variable was designated PSN J16103055+2730005 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2011ki based on the
spectroscopic confirmation of this as a type-II supernova on June 3 by Gal-Yam
et al. (cf. website URL http://www.astronomerstelegram.org/?read=3403; they
also observed 2011ki at mag 19.9 on June 3.38 UT, deriving position end
figures 30s.46, 29'59".2).  Further CCD magnitudes for 2011ki:  2011 May
20.41, [20.2 (CSS); June 3.357, 18.6 (J. Brimacombe, Cairns, Australia;
remotely using a 51-cm RCOS telescope + STL11K camera at the New Mexico Skies
observatory near Mayhill, NM, USA; position end figures 30s.48, 30"01".3;
