SUPERNOVA 2011V IN MCG +05-22-48
     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
 2011V   Jan. 28.29   9 27 38.76  +28 47 27.2   16.0    35" E, 27" S

Further unfiltered magnitudes for 2011V:  Jan. 10.39 UT, [19.5 (CSS); 29.157,
16.6 (R. A. Koff, Bennett, CO, U.S.A.; position end figures 38s.78, 27".0;
from five co-added images).  This object was designated PSN J09273876+2847275
on the Central Bureau's TOCP webpage due to a slightly different position
provided there by the discoverers.

     D. Milisavljevic, J. Parrent, and R. Fesen, Dartmouth College, report on
low-dispersion spectra (range 430-780 nm) taken on Feb. 2 and 3 UT with the
2.4-m Hiltner telescope (+ CCDS) at MDM Observatory.  A spectrum of PSN
J09273876+2847275 = SN 2011V indicates that it is likely a type-IIb supernova
approximately one week after maximum light.
