SUPERNOVAE 2014C IN NGC 7331

     Further to CBET 3772, M. Kim, W. Zheng, W. Li, and A. V. Filippenko,
University of California at Berkeley; and S. B. Cenko, Goddard Space Flight
Center, report the LOSS discovery of a supernova in NGC 7331 on unfiltered
KAIT images:

 SN       2014 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2014C    Jan. 5.09   22 37 05.60  +34 24 31.9   15.5    19".7 E, 24".2 S

The supernova was also detected at red mag about 17.1 three days earlier on a
pre-discovery image taken on Jan. 2.10 UT.  A finding chart was posted at URL
http://astro.berkeley.edu/~zwk/findingchart/PSN_J22370560+34243193.jpg.  The
variable was designated PSN J22370560+3424319 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014C based on the
spectroscopic confirmation reported below.  The type-II supernova 2013bu also
appeared in NGC 7331 (cf. CBET 3498).  Additional CCD magnitudes for 2014C:
2013 Dec. 26, [18.5 (KAIT); 2014 Jan. 4.861, 15.8 (Ron Arbour, South Wonston,
U.K.; 35-cm f/6 reflector; pre-discovery image; position end figures 05s.59,
31".3; offset 18" east, 25" south); 6.702, 15.3 (Gianluca Masi, Francesca
Nocentini, and Patrick Schmeer; remotely using a 43-cm telescope near Ceccano,
Italy; position end figures 05s.59, 31".4); 8.09, 14.5 (KAIT; measurement
after subtraction of background light).

Host galaxy info: vel= 816 km/s ; 10.5" x 3.7"; 10.35; SA(s)b; HII LINER
