SUPERNOVA 2014cp IN PGC 9204 = PSN J02253046-2537380
     S. Parker, Canterbury, New Zealand, reports the discovery of an apparent
supernova (red mag 15.7) on a 30-s unfiltered CCD image (limiting mag 19)
taken on June 23.760 UT with a 35-cm Celestron C14 reflector (+ ST10 camera)
at his Parkdale Observatory in the course of the Backyard Observatory
Supernova Search.  The new object is located at R.A. = 2h25m30s.46, Decl. =
-25d37'38".0 (equinox 2000.0; reference stars from USNO-B and UCAC4
catalogues), which is 29" east and 39" north of the nucleus of the galaxy
ESO 479-G1 = PGC 9204.  Nothing is visible at this position on Digitized Sky
Survey red and infrared images (limiting red magnitude > 19).  An image of
the variable can be viewed via website URL http://tinyurl.com/nuwk6ut.  The
variable was designated PSN J02253046-2537380 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014cp based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014cp:  June 25.83, 15.9 (H. Sato, Tokyo, Japan; remotely using a 0.43-m
f/6.8 astrograph + luminance filter; position end figures 30s.41, 38".0; no
star brighter than mag 20 is visible at this position on Palomar Sky Survey
images); 26.827, 16.2 (J. Brimacombe, Cairns, Australia; remotely using a
41-cm RCOS telescope + U9000 camera + luminance filter; position end figures
30s.47, 37".3).  Brimacombe has posted images of 2014cp at the following

     M. Childress, R. Scalzo, F. Yuan, B. Zhang, A. Ruiter, I. Seitenzahl, and
B. Schmidt, Australian National University (ANU); and B. Tucker, ANU and
University of California at Berkeley, report that spectroscopic classification
of PSN J02253046-2537380 = SN 2014cp was obtained on July 8.78 UT via a 60-min
exposure with the Wide Field Spectrograph (cf. Dopita et al. 2007, Ap. Space
Sci. 310, 255) on the ANU 2.3-m telescope at Siding Spring using the
B3000/R3000 gratings (wavelength range 350-980 nm at 0.1-nm resolution).  The
spectrum indicates that SN 2014cp is a broad-lined type-Ic supernova near
maximum light.  Classification with SNID (Blondin and Tonry 2007, Ap.J. 666,
1024) shows a good match to SN 1997dq at phase +1 day.  The preferred SNID
redshift is 0.00, as the broad lines make it difficult to constrain the
redshift compared to that of the apprent host galaxy, PGC 9204 (z = 0.0162;
Theureau et al. 1998, A.Ap. Suppl. 130, 333).
