SUPERNOVA 2013K IN ESO 9-G10 = PSN J17393154-8518381
     Stuart Parker, Canterbury, New Zealand, reports the discovery of an
apparent supernova (red mag 17.7) on a 30-s unfiltered CCD image (limiting mag
18.5) taken by himself on Jan. 20.413 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. =
17h39m31s.54, Decl. = -85d18'38".10 (equinox 2000.0; reference stars from
USNO-B and UCAC3 catalogues), which is 6" east and 1" south of the nucleus of
the galaxy ESO 9-G10.  Nothing is visible at this position on Digitized Sky
Survey red and infrared images (limiting red magnitude > 19) or on an image
taken by Parker on 2012 Dec. 9.491 (limiting red magnitude > 18).  Parker has
posted an image that can be viewed via website URL http://tinyurl.com/acupbro.
The variable was designated PSN PSN J17393154-8518381 when it was posted at
the Central Bureau's TOCP webpage and is here designated SN 2013K based on
the spectroscopic confirmation reported below.

Astronomical Observatory; S. Valenti, University of California at Santa
Barbara and Las Cumbres Observatory Global Telescope; S. Taubenberger,
Max-Planck-Institut fuer Astrophysik, Garching; S. J. Smartt, K. Smith, D.
Young, and M. Fraser, Queen's University, Belfast; M. Sullivan, University of
Southampton; and A. Gal-Yam and O. Yaron, Weizmann Institute for Science, on
behalf of the PESSTO collaboration (see Valenti et al., posted at website URL
http://www.astronomerstelegram.org/?read=4037), report that optical
spectroscopy (range 390-920 nm), obtained on Jan. 22.33 UT with the New
Technology Telescope (+ EFOSC2), show that PSN J17393154-8518381 = SN 2013K
is a type-IIP supernova a few days past maximum.  Balmer lines showing P-Cyg
profiles characterize the spectrum.  The absorption at rest wavelength 624 nm
is unusually strong.  PESSTO classification spectra can be obtained from
website URL http://www.pessto.org/; classification was made via SNID (Blondin
and Tonry 2007, Ap.J. 666, 1024).
