SUPERNOVA 2014bd
     Nozomu Tominaga, Konan University; Eric Hsiao, Nidia Morrell, Carlos
Contreras, Consuelo Gonzalez, and Mark Phillips, Las Campanas Observatory,
Carnegie Supernova Project; Satoru Fukuda, Hyogo, Japan; Tomoki Morokuma,
Institute of Astronomy, University of Tokyo; Masaomi Tanaka, National
Astronomical Observatory of Japan; and Emiko Matsumoto and Takumi Shibata,
Konan University, on behalf of the Kiso Supernova Survey (KISS) collaboration,
report the discovery of an apparent supernova (mag 20.0) on a g-band CCD image
(limiting mag 20.8) taken on Apr. 23.55 UT with the Kiso Wide Field Camera
(KWFC; 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. = 14h50m48s.07,
Decl. = +9d22'48".3 (equinox 2000.0), which is 1".4 west and 5".9 north of
the center of the galaxy SDSS J145048.16+092242.3.  Nothing is seen at this
position in an image taken on Mar. 31.73 (limiting mag 20.4).  The object was
confirmed with the Swope 1-m telescope at Las Campanas Observatory on Apr.
24.22 UT at magnitude r = 19.8.

     Nidia Morrell, Eric Hsiao, Carlos Contreras, Consuelo Gonzalez, and Mark
Phillips, Las Campanas Observatory, Carnegie Supernova Project, report that an
optical spectrogram (range 380-920 nm) of 2014bd was obtained on May 6.27 UT
with the Las Campanas 2.5-m du Pont telescope (+ WFCCD).  Inspection of the
data shows that 2014bd is a type-II supernova.  Cross-correlation with a
library of supernova spectra via the Supernova Identification tool (Blondin
and Tonry 2007, Ap.J. 666, 1024) provides many good matches with type II-p
supernovae within 10 days of maximum light.
