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 survey images:

 SN       2011 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2011db   May 12.30   13 49 05.90  +17 14 00.5   17.4    6".4 E, 17".1 S

This variable was designated PSN J13490590+1714005 when posted at the Central
Bureau's TOCP webpage and is here designated SN 2011db based on the
spectroscopic report below.  Further magnitudes for 2011db:  Apr. 25.22 UT,
[20.0 (Catalina Sky Survey); May 13.357, 17.2 (Joseph Brimacombe, Cairns,
Australia; from six stacked 1200-s images taken remotely using a 51-cm RCOS
telescope + red filter + STL11K camera at New Mexico Skies Observatory near
Mayhill, NM, U.S.A.; position end figures 05s.95, 13'59".6, which is near

     L. Tomasella, P. Ochner, S. Valenti, and S. Benetti, Istituto Nazionale
di Astrofisica, Osservatorio Astronomico di Padova; and A. Pastorello,
Dipartimento di Astronomia, Universita di Padova, on behalf of a larger
collaboration, report that a spectrogram (range 390-810 nm; resolution 2.2 nm)
of PSN 13490590+1714005 = SN 2011db, obtained on May 25.89 UT by the Service
Telescope Operator Team with the Ekar-Copernicus 1.82-m telescope (+ AFOSC),
is a type-II supernova, similar to SN 2007od (Inserra et al. 2011, posted at
website URL http://lanl.arxiv.org/abs/1102.5468) at a couple of weeks after
explosion.
