SUPERNOVA 2014cv IN UGC 10123 = PSN J15590359+5118180
     Further to CBET 3855, S. Kumar, W. Zheng, and A. V. Filippenko,
University of California at Berkeley, report the LOSS discovery of a possible
supernova in UGC 10123 on unfiltered KAIT images:

 SN       2014 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2014cv   May 31.37   15 59 03.59  +51 18 18.0   20.0    7".7 E, 1".8 N

Due to close distance to the host galaxy core, it is hard to measure the
magnitude of the target.  A finding chart was posted at the following website
URL:  http://astro.berkeley.edu/~zwk/findingchart/PSN_J15590359+51181800.jpg.
The variable was designated PSN J15590359+5118180 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014cv based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014cv:  June 1.869, 19.5 (G. Masi; remotely using a 43-cm telescope at
Ceccano, Italy; position end figures 03s.61, 19".0); 2.309, 19.6 (J.
Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope +
STXL-6303 camera at the New Mexico Skies observatory near Mayhill, NM, USA;
position end figures 03s.56, 18".6; image posted at website URL

     W. Zheng, M. L. Graham, P. L. Kelly, J. C. Mauerhan, and A. V.
Filippenko, University of California, Berkeley, report that inspection of a
CCD spectrogram (range 450-960 nm), obtained on June 26.43 UT with the 10-m
Keck II telescope (+ DEIMOS spectrograph), shows that PSN J15590359+5118180 =
SN 2014cv is a type-IIP supernova.  The spectrum exhibits a red continuum and
H-alpha having a clear P-Cyg profile.  Cross-correlation with a library of
supernova spectra using the "SuperNova Identification" code (SNID; Blondin and
Tonry 2007, Ap.J. 666, 1024) indicates a similarity with a number of type-IIP
supernovae at about a month to several months after the explosion.
