SUPERNOVA 2014U IN NGC 3859
     Masaomi Tanaka, National Astronomical Observatory of Japan; M. M.
Phillips and E. Y. Hsiao, Las Campanas Observatory; S. Holmbo and C.
Contreras, Aarhus University; Hiroshi Akitaya and Yuki Moritani, Hiroshima
University; Satoru Fukuda, Hyogo, Japan; Katsuhiko Mameta, Hyogo, Japan;
Koichi Takahashi, Osaka, Japan; Tomoki Morokuma, Institute of Astronomy,
University of Tokyo; and Nozomu Tominaga, Konan University, on behalf of the
Kiso Supernova Survey collaboration, report the discovery of an apparent
supernova (mag 18.9) on a g-band CCD image (limiting mag 20.6) taken on Feb.
23.53 UT with the Kiso Wide Field Camera (field-of-view 2.1 deg x 2.1 deg)
on the 1.05-m Kiso Schmidt telescope at the Kiso Observatory.  The new object
is located at R.A. = 11h44m52s.16, Decl. = +19d27'17".8 (equinox 2000.0),
which is 1".0 west and 2".8 north of the center of the galaxy NGC 3859.
Nothing is seen at this position in an image taken on Jan. 31.82 (limiting
mag 20.6).

     E. Y. Hsiao, M. M. Phillips, and N. Morrell, Las Campanas Observatory;
G. H. Marion, University of Texas, Austin; C. Contreras, C. Gall, and M.
D. Stritzinger, Aarhus University; and R. P. Kirshner, Harvard-Smithsonian
Center for Astrophysics, report that a near-infrared spectrogram (range
810-2400 nm) of SN 2014U was obtained on Feb. 27.22 UT with the FoldedPort
Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope. 
The spectrum shows that 2014U is a type-II supernova, approximately three
weeks past explosion.  The near-infrared spectrum is similar to that of SN
2013hj at approximately 21 days past explosion with several hydrogen Paschen
P-Cyg lines.  The supernova redshift approximately matches the redshift of
the presumed host galaxy (NGC 3859) at z = 0.01824 (Haynes et al. 1997, Ap.J.
113, 1197; via NED).
