SUPERNOVA 2011bp = PSN J11122996+3123055
     Further to CBET 2678, S. B. Cenko, W. Li, and A. V. Filippenko report the
LOSS discovery of an apparent supernova on unfiltered KAIT images.  The object
was designated PSN J11122996+3123055 when posted on the Central Bureau's TOCP
webpage and is here designated SN 2011bp based on the spectroscopic report
below.

 SN       2011 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2011bp   Apr. 6.32   11 12 29.96  +31 23 05.5   18.2    3".1 W, 0".3 S

Additional KAIT magnitudes for 2011bp:  Feb. 12.15 UT, [19.3; Apr. 10.31, 18.6.

     J. M. Silverman and A. V. Filippenko, University of California, Berkeley,
report that inspection of a low-signal-to-noise-ratio CCD spectrum (range
340-1000 nm), obtained by V. N. Bennert (University of California, Santa
Barbara) on Apr. 13 UT with the 3-m Shane reflector (+ Kast) at Lick
Observatory, shows that PSN J11122996+3123055 = SN 2011bp is likely a type-Ib
supernova.
