SUPERNOVA 2014cr IN NGC 6806 = PSN J19370613-4217505
     L. A. G. Monard, Calitzdorp, Western Cape, South Africa, reports his
discovery of an apparent supernova (mag 17.8) on several unfiltered CCD images
taken with a 35-cm RCX400 telescope (+ SBIG ST8-XME camera) on June 27.860 UT
at his Klein Karoo Observatory.  The new object is located at R.A. =
19h37m06s.13, Decl. = -42d17'50".5 (equinox 2000.0), which is 12" east and 3"
south of the center of the Sc-type galaxy NGC 6806.  His images have been
posted at website URL http://www.rochesterastronomy.org/supernova.html.  The
variable was designated PSN J19370613-4217505 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014cr based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014cr:  May 22.95, [18.8 (Monard); June 28.997, 17.7 (Monard); 30.579, 17.8
(J. Brimacombe, Cairns, Australia; remotely using a 41-cm telescope at the
Warrumbungle Observatory, Siding Spring; position end figures 06s.10, 50".7;

July 2.975, 17.7 (Monard).

     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 J19370613-4217505 = SN 2014cr was obtained on July 8.48 UT via a
180-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 2014cr is a peculiar type-Ia supernova similar to the
2002cx-like subclass sometimes referred to as type-Iax supernovae, with very
narrow lines typical of this class.  Classification with SNID (Blondin and
Tonry 2007, Ap.J. 666, 1024) shows a good match to SN 2005hk at phase +23
days, and the preferred SNID redshift is about 0.020, consistent with the
apparent host galaxy, NGC 6806 (z = 0.0191; via HIPASS catalogue).
