SUPERNOVA 2014H = PSN J03370148+3205017
     Wenxiong Li, Jun Mo, and Xiaofeng Wang, Tsinghua University (THU); and
Tianmeng Zhang, National Astronomical Observatories of China (NAOC), report
the discovery of an apparent supernova (mag 16.8) on unfiltered CCD images
taken on Jan. 14.56 UT using the 0.6-m NAOC Schmidt telescope in the course of
the THU-NAOC Transient Survey (TNTS).  The object is located at R.A. =
3h37m01s.48, Decl. = +32d05'01".7 (equinox 2000.0), which is 0".2 east and
9".4 north of the center of the galaxy 2MASX J03370146+3204521.  Nothing is
visible at this position on a Digitized Sky Survey image from the Palomar Sky
Survey.  The variable was designated PSN J03370148+3205017 when it was posted
at the Central Bureau's TOCP webpage and is here designated SN 2014H based on
the spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014H:  2013 Dec. 8, [20.0 (TNTS); 2014 Jan. 15.257, 16.3 (Joseph Brimacombe,
Cairns, Australia; remotely using a 43-cm CDK telescope + STL-6303 camera +
nfrared filter at the New Mexico Skies observatory near Mayhill, NM, U.S.A.;
bandpass > 700 nm; position end figures 01s.41, 04'59".4; image posted at URL

Masi, F. Nocentini, and P. Schmeer; remotely using a 43-cm telescope near
Ceccano, Italy; position end figures 01s.35, 05'01".6).

     J.-J. Zhang, Yunnan Astronomical Observatory (YNAO); and X.-F. Wang,
Tsinghua University, report on an optical spectrogram (range 350-890 nm) of
PSN J03370148+3205017 = SN 2014H that was obtained on Jan. 15.60 UT with the
2.4-m telescope (+ YFOSC) at the LiJiang Gaomeigu Station of YNAO.  The
spectrum is consistent with a type-Ia supernova a few days before maximum.
Cross-correlation with a library of supernova spectra using the "Supernova
Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows
that 2014H matches with SN 2005na at -2 days.  The host galaxy, 2MASX
J03370146+3204521, seems to have a redshift of 0.015 +/- 0.001 from the SNID
fit.
