SUPERNOVA 2014cj IN ESO 87-G31 = PSN J06363000-6643540
     S. Parker, Canterbury, New Zealand, reports the discovery of an apparent
supernova (red mag 17.0) on a 30-s unfiltered CCD image (limiting mag 18.5)
taken by himself on Aug. 13.731 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. = 6h36m30s.00, Decl. = -66d43'54".0 (equinox 2000.0; reference stars from
USNO-B and UCAC4 catalogues), which is 10" east and 17" north of the nucleus
of the galaxy ESO 87-G31.  Nothing is visible at this position on Digitized
Sky Survey red and infrared images (limiting red mag > 19).  An image of the
variable can be seen via website URL http://tinyurl.com/p372jrn.  The variable
was designated PSN J06363000-6643540 when it was posted at the Central
Bureau's TOCP webpage and is here designated SN 2014cj based on the
spectroscopic confirmation reported below.

Observatory, report that an optical spectrogram of PSN J06363000-6643540 = SN
2014cj, obtained on Aug. 15 UT with the ESO New Technology Telescope at La
Silla using EFOSC2 and Grism 13 (range 398.5-931.5 nm, 1.8-nm resolution)
under the Public ESO Spectroscopic Survey for Transient Objects (see website
URL http://www.pessto.org), shows that this is a normal type-Ia supernova at
about three weeks after B-band maximum light.  Classifications were done with
SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) and GELATO (Harutyunyan et al.
2008, A.Ap. 488, 383).  Classification spectra can be obtained from website
