SUPERNOVA 2011K
     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; E. C. Beshore and S. M.
Larson, Lunar and Planetary Laboratory, University of Arizona; and E.
Christensen, Gemini Observatory, report the Catalina Real-time Transient
Survey's discovery of an apparent supernova in unfiltered Catalina Sky Survey
(CSS) images:

 SN       2011 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2011K    Jan. 13.19   4 45 30.38  - 7 20 52.7   15.1      2" S

Nothing is visible at this position on a CSS image from 2010 Dec. 10.32 UT
(limiting mag 19.0).
     After posting on the "Transient Object Confirmation Page", R. A. Koff
(Antelope Hills Observatory, Colorado) reports that thirteen images obtained
around Jan. 14.069 UT reveal mag 15.1 and position end figures 30s.38, 53".2
for 2011K.

     K. Ayani, Bisei Astronomical Observatory (BAO); and H. Yamaoka, Kyushu
University, report that low-resolution spectra (range 400-750 nm; resolution
0.6 nm at H-alpha) of 2011K were obtained with the BAO 1.01-m telescope on
Jan. 13.6 UT.  The spectra show that 2011K is a type-Ia supernova, several
days before maximum.
