SUPERNOVA 2014ee IN UGC 4132 = PSN J07591099+3254392 = PSN J07591178+3254399
     A. Kroes, J. Newton, D. Post, W. Pattishall, and T. Puckett report the
discovery of an apparent supernova (mag 17.3) on CCD images (limiting mag
19.0) taken with a 0.40-m reflector at Portal, AZ, U.S.A., on 2014 Nov. 12.347
UT in the course of the Puckett Observatory Supernova Search.  The new object
is located at R.A. = 7h59m11s.68, Decl. = +32o54'39".6 (equinox 2000.0), which
is 17".1 west and 14".0 south of the center of UGC 4132.  The variable was
designated PSN J07591099+3254392 when it was posted at the Central Bureau's
TOCP webpage with position end figures 10s.99, 39".2 (and offset 25" west and
15" south of the center of UGC 4132) and is here designated SN 2014ee based on
the spectroscopic confirmation reported below; the object was also designated
PSN J07591178+3254399 on the TOCP automatically when it was posted as an
independent discovery by K. Itagaki on 2014 Dec. 12 (see below).  The type-II
supernova 2005en and the type-Ic supernova 2005eo also appeared simultaneously
in UGC 4132 (cf. IAUC 8605).  Additional CCD magnitudes for 2014ee:  2014
Oct. 30, [18.9 (Newton; communicated by Puckett); Nov. 17.524, 17.0 (Post,
0.60-m reflector at Mayhill; communicated by Puckett); 24.982, 16.9 (G. Masi
and P. Catalano; remotely using a 43-cm telescope at Ceccano, Italy; position
end figures 11s.72, 39".6); Dec. 12.706, 16.8 (K. Itagaki, Teppo-cho,
Yamagata, Japan; independent discovery; position end figures 11s.78, 39".9;
offset 15" west, 14" south); 17.920, 17.5 (Masi and Catalano; position end
figures 11s.74, 40".2).

     P. Ochner, S. Benetti, A. Pastorello, L. Tomasella, E. Cappellaro, N.
Elias-Rosa, L. Tartaglia, G. Terreran, and M. Turatto, Osservatorio Astronomico
di Padova, INAF, report that an optical spectrogram (range 340-820 nm;
resolution 1.2 nm) of PSN J07591099+3254392 = SN 2014ee, obtained on 2014 Nov.
24.94 UT with the Asiago 182-cm Copernico Telescope (+ AFOSC) in the framework
of the Asiago Transient Classification Program (Tomasella et al. 2014, AN 335,
841), shows that this a young type-IIn supernova.  The spectrum displays a
blue continuum with super-imposed Balmer lines with composite profiles; they
consist of broad (FWHM about 12500 km/s) and narrow (barely resolved)
emissions.  The Asiago classification spectra are posted at the following
