Abstract (from CDS):

A. J. Drake, S. G. Djorgovski, A. Mahabal, M. J. Graham, and R. Williams, California Institute of Technology; J. L. Prieto, Princeton University; M. Catelan, Pontificia Universidad Catolica de Chile; 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 in unfiltered Catalina Sky Survey (CSS) images:

---------------------------------------------------------------------------— SN 2011 UT R.A. (2000.0) Decl. Mag. Offset ---------------------------------------------------------------------------— 2011hc Oct. 23.16 20 12 10.07 -11 21 57.7 16.5 0".8 N ---------------------------------------------------------------------------—

The variable was designated PSN J20121007-1121577 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011hc based on the spectroscopic confirmation reported below. Additional CCD magnitudes (unfiltered unless otherwise noted) for 2011hc: 2010 Nov. 18.10 UT, [19.0 (CSS); 2011 Oct. 26.177, 16.4 (Joseph Brimacombe, Cairns, Australia; position end figures 10s.11, 56".6; image posted at the following website URL: http://www.flickr.com/photos/43846774@N02/6290844088/); 29.06, 16.5 (R. A. Koff, Bennett, CO, USA; Meade 0.25-m f/10 Schmidt-Cassegrain reflector + Apogee AP-47p CCD camera; position end figures 10s.06, 57".1; UCAC3 reference stars; image scale 2"/pixel; limiting magnitude 18.4); 29.898, R = 16.7 (Federica Luppi, Varese, Italy, 0.36-m f/7.9 reflector + Bessell R filter; position end figures 10s.10, 56".4; reference stars from CMC-14 catalogue; image posted at http://www.astrogeo.va.it/pub/TOCP/PSN_20121007-1121577.jpg).
