SUPERNOVA 2014dz = PSN J03281419+3801111
     R. Gagliano, J. Newton, W. Pattishall, D. Post, and T. Puckett report the
discovery of an apparent supernova (mag 17.3) on CCD images (limiting mag
19.0) taken with a 0.35-m reflector at Portal, AZ, USA, on 2014 Dec. 20.146 UT
in the course of the Puckett Observatory Supernova Search.  The new object is
located at R.A. = 3h28m14s.19, Decl. = +38o01'11".1 (equinox 2000.0), which is
8".0 east and 12".7 north of the center of PGC 213221.  The variable was
designated PSN J03281419+3801111 when it was posted at the Central Bureau's
TOCP webpage and is here designated SN 2014dz based on the spectroscopic
confirmation reported below.  Additional CCD magnitudes for 2014dz:  2014 Aug.
16, [19.4 (Puckett); Dec. 21.055, 17.1 (G. Masi and P. Catalano; remotely
using a 43-cm telescope at Ceccano, Italy; position end figures 14s.22,
10".8); 21.149, 17.1 (D. Post; 0.60-m reflector at Mayhill, NM, USA;
communicated by Puckett).

     D. D. Balam, Dominion Astrophysical Observatory, National Research
Council of Canada, M. L. Graham, Las Cumbres Observatory Global Telescope,
University of California at Santa Barbara; and E. Y. Hsiao, Aarhus University,
report that a spectrogram (range 365-720 nm, resolution 0.3 nm) of PSN
J03281419+3801111 = SN 2014dz, obtained on 2014 Dec. 31.16 UT with the 1.82-m
Plaskett Telescope of the National Research Council of Canada, shows it to be
a type-Ia supernova approximately nine days past maximum light.  Cross-
correlation with a library of supernova spectra using the "Supernova
Identification" code (Blondin and Tonry 2007, Ap.J. 666,1024) indicates that
2014dz is most similar to the type-Ia supernova 2003du at 9 days past maximum
light.  The photospheric velocity estimated from the Si II 635.5-nm feature
is about 8700 km/s.
