SUPERNOVA 2011kh IN NGC 7189 = PSN J22031514+0034253
     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
 2011kh   June 7.42   22 03 15.14  + 0 34 25.3   18.5    12".8 W, 9".1 N

The variable was designated PSN J22031514+0034253 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2011kh based on the
spectroscopic confirmation of this as a type-II supernova on June 24 by
Gal-Yam et al. (cf. website URL http://www.astronomerstelegram.org/?read=3464;
they also observed 2011kh at mag 18.1 on June 13.46 UT, deriving position end
figures 15s.00, 24".9).  Additional CCD magnitudes for 2011kh:  2011 May
13.45, [19.7 (CSS); June 8.441, 17.7 (J. Brimacombe, Cairns, Australia; image
taken remotely with a telescope at the New Mexico Skies observatory near
Mayhill, NM, USA; position end figures 15s.03, 25".5; image posted at website

26.033, R = 18.1 (F. Luppi, Varese, Italy; 0.36-m f/7.9 reflector + Bessell R
filter; position end figures 15s.04, 25".3; something is faintly visible at
this position on Digitized Sky Survey images from 1990 Aug. 16 and 19
around red mag 19 and position end figures 15s.03 +/- 0s.02 and 25".2 +/-
0".3; image posted at URL http://www.astrogeo.va.it/pub/TOCP/PSN_N7189.jpg);
