SUPERNOVA 2014br IN ESO 147-G17 = PSN J22595069-6133222
     S. Parker, Canterbury, New Zealand, reports the discovery of an apparent
supernova (red mag 16.5) on a 30-s unfiltered CCD image (limiting mag 18.5)
taken by himself on May 5.744 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. = 22h59m50s.69, Decl. = -61d33'22".2 (equinox 2000.0; reference stars
from USNO-B and UCAC4 catalogues), which is 8" east and 30" north of the
nucleus of the galaxy ESO 147-G17.  Nothing is visible at this position on
Digitized Sky Survey red and infrared images (limiting red mag > 18).  An
image of the variable is viewable via website URL http://tinyurl.com/p7ota7c.
The variable was designated PSN J22595069-6133222 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014br based on the
spectroscopic confirmation reported below.  Images taken by J. Brimacombe
(Cairns, Australia) remotely using a 41-cm RCOS telescope (+ U9000 camera +
luminance filter) of the Warrumbungle Observatory at Siding Spring on June
6.776 show 2014br at mag 17.0 with position end figures 50s.67, 22".0; his
images are posted at https://www.flickr.com/photos/43846774@N02/14363756372/.

     G. H. Marion, University of Texas at Austin and Harvard-Smithsonian
Center for Astrophysics (CfA); E. Y. Hsiao, Aarhus University; R. P. Kirshner,
CfA; C. Gall and M. D. Stritzinger, Aarhus University; and C. Contreras, N.
Morrell, and M. M. Phillips, Las Campanas Observatory, report that near-
infrared spectroscopy (range 800-2400 nm) of PSN J22595069-6133222 = SN 2014br
was obtained with the FoldedPort Infrared Echellette (FIRE) spectrograph on
the 6.5-m Magellan Baade Telescope on June 6 UT, showing that 2014br is a
core-collapse supernova with no evidence for hydrogen; specifically, it is a
type-Ibc supernova at 3-4 weeks after maximum.
