SUPERNOVA 2014ce IN NGC 7673 = PSN J23274086+2335214
     Further to CBET 3892, H. Kim, W. Zheng, and A. V. Filippenko, University
of California at Berkeley, report the LOSS discovery of an apparent supernova
in NGC 7673 on unfiltered KAIT images:

 SN       2014 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2014ce   Aug. 9.52   23 27 40.86  +23 35 21.4   17.0    2".9 W, 1".4 N

The discoverers posted a finding chart for 2014ce at the following website
URL:  http://astro.berkeley.edu/~zwk/findingchart/PSN_J23274086+23352144.jpg.
The variable was designated PSN J23274086+2335214 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014ce based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014ce:  Aug. 8, [17.5 (KAIT; after subtraction); 9.966, 16.5-17.0 (G. Masi,
P. Catalano, and P. Schmeer; remotely using a 43-cm telescope at Ceccano,
Italy; source embedded in galaxy's light; position end figures 40s.82, 21".3;
image posted at http://www.virtualtelescope.eu/psnPSNJ23274086+2335214.jpg);
10.36 UT, 16.7 (KAIT); 11.37, 16.4 (KAIT); 12.915, 16.0 (Masi et al.;
36-cm telescope; position end figures 40s.86, 21".3).

     S. T. Hodgkin, M. Fraser, H. Campbell, and G. T. Rixon, University of
Cambridge; L. Wyrzykowski, Warsaw Observatory; and A. Pastorello, N.
Elias-Rosa, and L. Tartaglia, Osservatorio Astronomico di Padova, INAF, report
the spectroscopic classification of PSN J23274086+2335214 = SN 2014ce using
the EFOSC2 spectrograph equipped with Grism 13 (range 398.5-931.5 nm; 1.8-nm
resolution) on the 3.6-m New Technology Telescope at La Silla on Aug. 20.33
UT.  The spectrum shows a blue continuum, Balmer lines with P-Cyg profiles,
and He I, consistent with a type-II supernova around seven to ten days after
explosion and at a redshift of 0.011.
