SUPERNOVA 2011ay IN NGC 2315

     Further to CBET 2651, P. Blanchard, 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
 2011ay   Mar. 18.18   7 02 34.06  +50 35 25.0   17.7    9".3 E, 1".4 S

Nothing was visible at this position on a KAIT image from Mar. 1.22 UT
(limiting mag 19.6).  The object was designated PSN J07023406+5035250 when
posted on the Central Bureau's TOCP webpage, and it is here designated SN
2011ay based on the spectroscopic report below.  Joseph Brimacombe (Cairns,
Australia) writes that he obtained sixteen 600-s exposures on Mar. 20.204
remotely with a 51-cm RCOS telescope (+ STL11K camera) at the New Mexico
Skies Observatory near Mayhill, NM, U.S.A., which yield mag 16.8 and
position end figures 34s.09, 24".6 for 2011ay; he has posted his images at
