SUPERNOVA 2014an
     Nozomu Tominaga and Emiko Matsumoto, Konan University; Eric Hsiao, Carlos
Contreras, Carlos Corco, Nidia Morrell, and Mark Phillips, Las Campanas
Observatory; Masaomi Tanaka and Nobuharu Ukita, National Astronomical
Observatory of Japan; Kyohei Kawaguchi and Sho Fujibayashi, Kyoto University;
Satoru Fukuda, Hyogo, Japan; Koichi Takahashi, Osaka, Japan; and Tomoki
Morokuma, Institute of Astronomy, University of Tokyo, on behalf of the Kiso
Supernova Survey (KISS) collaboration, report the discovery of an apparent
supernova (mag 18.6) on a g-band CCD image (limiting mag 19.8) taken on Mar.
31.68 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. = 14h51m42s.93, Decl. = +8d34'12".5 (equinox
2000.0), which is 5".3 east and 15".8 north of the center of the galaxy SDSS
J145142.57+083356.6.  Nothing is seen at this position in an image taken on
Feb. 24.65 (limiting mag 20.1).  The variable was confirmed with the Swope 1-m
telescope at Las Campanas Observatory on Apr. 2.83 at V = 18.9.

     Masaomi Tanaka, National Astronomical Observatory of Japan; Emiko
Matsumoto, Konan University; Kyohei Kawaguchi and Sho Fujibayashi, Kyoto
University; Nobuharu Ukita and Ikuru Iwata, National Astronomical Observatory
of Japan; Nozomu Tominaga, Konan University; and Tomoki Morokuma, Institute of
Astronomy, University of Tokyo, on behalf of the KISS project, report that an
optical spectrum of SN 2014an was obtained on Apr. 2.7 UT with the Okayama
188-cm telescope (+ Kyoto Okayama Optical Low-dispersion Spectrograph).
Cross-correlation with a library of supernova spectra using the "Supernova
Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows
good matches with type-Ia supernovae around maximum light.
