SUPERNOVAE 2014B IN NGC 4939

     Further to CBET 3743, H. 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 4939 on unfiltered
KAIT images.  The discovery observation is tabulated below:

 SN       2014 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2014B    Jan. 2.60   13 04 17.70  -10 20 01.2   17.0    48".6 E, 21".7 N

Nothing was detected at this position on a KAIT image obtained on 2013 June
11.2 UT (limiting mag about 18.5).  A finding chart was posted at website URL
http://astro.berkeley.edu/~zwk/findingchart/PSN_J13041770-10200121.jpg.  The
variable was designated PSN J13041770-1020012 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014B based on the
spectroscopic confirmation reported below.  The type-II supernova 2008aw (cf.
CBET 1279) also appeared in NGC 4939, as did SNe 1968X (IAUC 2116) and 1973J
(IAUC 2538).
