SUPERNOVA 2013Z = PSN J13275489+3022294
     Tianmeng Zhang and Xu Zhou, National Astronomical Observatories of China
(NAOC); and Xiaofeng Wang and Juncheng Chen, Tsinghua University (THU), report
the discovery of an apparent supernova (mag 19.0) on unfiltered CCD images
taken on Jan. 24.90 UT using the 0.6-m NAOC Schmidt telescope in the course of
the THU-NAOC Transient Survey (TNTS).  The new object is located at R.A. =
13h27m54s.89, Decl. = +30d22'29".4 (equinox 2000.0), which is about 6" west
and 5" south of the center of the galaxy KUG 1325+306.  Nothing is visible at
this position on archival images obtained on Jan. 5 (limiting mag about 20.0)
or on Digitized Sky Survey images from the Palomar Sky Survey.  The variable
was also detected at mag 19.2 on Jan. 25.  A TNTS image is posted at website
URL http://www.thca.tsinghua.edu.cn/~wangxf/TNTS/PSNJ132754+302229.jpg.  The
variable was designated PSN J13275489+3022294 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2013Z based on the
spectroscopic confirmation reported below.

     C. Inserra, E. Gall, M. Fraser, and S. J. Smartt, Queens University,
Belfast; and Andy Lawrence, University of Edinburgh, report that a spectrogram
(range 330-975 nm; resolution about 500) of PSN J13275489+3022294 = SN 2013Z
was obtained on Feb. 10.13 UT with the 4.2-m William Herschel Telescope (+
ISIS).  Cross-correlation with a library of supernova spectra via the
"Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) shows that 2013Z is a type-II supernova at a redshift of z = 0.05.  They
find good matches to several normal type-IIP supernovae at ages of between 2
and 4 weeks.
