SUPERNOVA 2014cz IN ESO 294-G21 = PSN J00321454-4122559
     S. Parker, Canterbury, New Zealand, reports the discovery of an apparent
supernova (red mag 17.2) on a 30-s unfiltered CCD image (limiting mag 18.5)
taken by himself on Sept. 2.443 UT with a 30-cm Astro-Tech AT12RC Ritchey-
Chretien astrograph (+ ST10 camera) at his Parkdale Observatory in the course
of the Backyard Observatory Supernova Search.  The new object is located at
R.A. = 0h32m14s.54, Decl. = -41d22'55".9 (equinox 2000.0; reference stars from
USNO-B and UCAC4 catalogues), which is 3" west and 6" north of the nucleus of
the galaxy ESO 294-G21.  Nothing is visible at this position on Digitized Sky
Survey red and infrared images (limiting red mag > 19).  An image of the new
object is viewable at website URL http://tinyurl.com/opl8c3d.  The variable
was designated PSN J00321454-4122559 when it was posted at the Central
Bureau's TOCP webpage and is here designated SN 2014cz based on the
spectroscopic confirmation reported below.

     N. Morrell, M. M. Phillips, and C. Contreras, Las Campanas Observatory;
G. H. Marion, University of Texas, Austin; E. Y. Hsiao, C. Gall, and M. D.
Stritzinger, Aarhus University; and R. P. Kirshner, Harvard-Smithsonian Center
for Astrophysics, report on the spectroscopic classification of PSN
J00321454-4122559 = SN 2014cz using a near-infrared spectrogram (range
800-2500 nm) obtained on Sept. 3.23 UT with the FoldedPort Infrared Echellette
(FIRE) spectrograph on the 6.5-m Magellan Baade Telescope at Las Campanas.
The near-infrared spectrum shows that 2014cz is a type-Ia supernova.  The
spectrum resembles the near-infrared spectrum of SN 2013gy at 22 days past
maximum light.  The supernova redshift approximately matches the redshift of
the presumed host galaxy (ESO 294-G21) at z = 0.0260 (Mathewson et al. 1996,
Ap.J. Suppl. 107, 97).
