SUPERNOVA 2012at IN PGC 16317 = PSN J04545281-3719161
     S. Howerton, Arkansas City, KS, U.S.A.; 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; 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, report the
discovery of an apparent supernova in public images from the Catalina Sky
Survey.

 SN       2012 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2012at   Feb. 6.51    4 54 52.81  -37 19 16.1   17.7    0".9 W, 1".1 S

The variable was designated PSN J04545281-3719161 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2012at based on the
spectroscopic confirmation reported below.  Further CCD magnitudes for
2012at:  2011 Nov. 19.65 UT, [18.9 (Siding Spring Survey; via Drake et al.);
2012 Feb. 17.438, 15.6 (Joseph Brimacombe, Cairns, Australia; 41-cm RCOS
telescope + STL6K camera + infrared filter; wavelength bandpass > 700 nm;
position end figures 52s.82, 17".2; image posted at the following website URL:

     M. Fraser, T.-W. Chen, S. J. Smartt, and R. Kotak, Queen's University,
Belfast, report that they obtained a spectrum (range 530-975 nm; resolution
about 0.4 nm) of PSN J04545281-3719161 = SN 2012at on Mar. 3.83 UT with the
4.2-m William Herschel Telescope (+ ISIS).  Cross-correlation with a library
of template spectra using the "Supernova Identification" code (SNID; Blondin
and Tonry 2007, Ap.J. 666, 1024) gives a good match to the type-Ic supernova
1995F, at +3 weeks.
