SUPERNOVA 2015be IN NGC 1843 = PSN J05140624-1037300
     Further to CBET 4190, S. Stegman, W. Zheng, and A. V. Filippenko,
University of California at Berkeley, report the LOSS discovery of an
apparent supernova in NGC 1843 on unfiltered KAIT images:

 SN       2015 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2015be   Dec. 6.399   5 14 06.24  -10 37 30.0   18.0    1".3 E, 6".5 N

The discoverers have posted a finding chart for the variable at website URL
http://w.astro.berkeley.edu/~zwk/findingchart/PSN_J05140624-10373000.jpg.
The variable was designated PSN J05140624-1037300 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2015be based on the
spectroscopic confirmation reported below.  Additional approximate unfiltered
CCD magnitudes for 2015be:  Dec. 2 UT, [18.2 (KAIT); 7.648, 17.7 (K. Shima,
Fujimi-machi, Nagano, Japan; 45-cm f/4.6 reflector + FLI ML-8300 camera;
60-s exposure; position end figures 06s.18, 29".9).

     W. Zheng, I. Shivvers, H. Yuk, and V. Filippenko, University of
California, Berkeley, report that a CCD spectrogram (range 350-1000 nm) of
PSN J05140624-1037300 = SN 2015be was obtained on Dec. 9.345 UT with the
Shane 3-m reflector (+ Kast spectrograph) at Lick Observatory.  The spectrum
shows that 2015be is a type-IIP supernova.  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 several type-IIP
supernovae several days after explosion.  The redshift, derived from the
narrow H_alpha emission line (which is likely contributed from the host
glaxy), is z = 0.0087, consistent with the redshift of the putative host
galaxy, NGC 1843, with z = 0.00868 as given in NED (Koribalski et al., 2004,
A.J. 128, 16).
