SUPERNOVA 2014cq IN PGC 26596 = PSN J09232955-6340283
     S. Parker, Canterbury, New Zealand, reports the discovery of an apparent
supernova (red mag 16.8) on a 30-s unfiltered CCD image (limiting mag 18.5)
taken by himself on June 20.347 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. = 9h23m29s.55, Decl. = -63d40'28".3 (equinox 2000.0; reference stars
from USNO-B and UCAC4 catalogues), which is 20" east and 16" north of the
nucleus of the galaxy PGC 26596 = ESO 91-G11.  Nothing is visible at this
position on Digitized Sky Survey red and infrared images (limiting red mag >
19).  An image of the variable is viewable at URL http://tinyurl.com/n8gh2x8.
The variable was designated PSN J09232955-6340283 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014cq based on the
spectroscopic confirmation reported below.  J. Brimacombe, Cairns, Australia,
reports mag 17.1 and position end figures 29s.53, 28".2 for 2014cq from
images taken remotely on June 22.55 using a 41-cm RCOS telescope (+ U9000
camera + luminance filter) at the Warrumbungle Observatory, Siding Spring
(images posted at https://www.flickr.com/photos/43846774@N02/14313608820/).

     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 J09232955-6340283 = SN 2014cq was obtained on July 8.38 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 2014cq is a type-IIb supernova a few weeks past
maximum light, with clear signatures of both H and He in the spectrum.
Classification with SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) shows a
good match to SN 2003bg at phase +20 days, and the preferred SNID redshift is
about 0.011, consistent with the apparent host galaxy, PGC 26596 (z = 0.0107,
via the HIPASS catalogue).
