SUPERNOVA 2011O IN UGC 8829 = PSN J13541996+3255394
     Further to CBET 2640, A. Narla, S. B. Cenko, W. Li, and A. V. Filippenko
report the LOSS discovery of an apparent supernova on unfiltered KAIT images:

 SN       2011 UT        R.A. (2000.0) Decl.      Mag.      Offset
 2011O    Jan. 18.56   13 54 19.96  +32 55 39.4   18.1    0".8 E, 8".5 S

Additional KAIT magnitudes for 2011O:  a co-added frame from 2010 Apr.-July,
[19.5; 2011 Jan. 25.50 UT, 18.3.  This object was posted on the Central
Bureau's TOCP webpage with provisional designation PSN J13541996+3255394
and is here designated SN 2011O.

     J. M. Silverman, A. T. Merritt, F. Fornasini, and A. V. Filippenko,
University of California, Berkeley, report that inspection of a CCD spectrum
(range 340-1000 nm), obtained on Jan. 26 UT with the 3-m Shane reflector (+
Kast) at Lick Observatory, shows that 2011O is a type-II supernova with
well-developed P-Cyg line profiles.  After removal of the host-galaxy
recession velocity of 7845 km/s (measured from narrow host-galaxy emission
lines), they find the absorption minimum of the H-alpha line to be blue-
shifted by about 6600 km/s.
