SUPERNOVA 2014ed
     Tomoki Morokuma, Institute of Astronomy, University of Tokyo; Nozomu
Tominaga, Emiko Matsumoto, and Takumi Shibata, Konan University; Masaomi
Tanaka, National Astronomical Observatory of Japan; and Satoru Fukuda, Hyogo,
Japan -- on behalf of the Kiso Supernova Survey (KISS) collaboration -- report
the discovery of an apparent supernova (mag 19.5) on a g-band CCD image
(limiting mag 20.9) taken on 2014 Nov. 21.76 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.
The new object is located at R.A. = 9h29m13s.75, Decl. = +22d34'36".4 (equinox
2000.0), which is 1".2 east and 0".3 south of the center of the galaxy
SDSS J092913.67+223436.6.

Doi, Shigeyuki Sako, Yuki Kikuchi, Hidenori Takahashi, and Ken Tateuchi,
University of Tokyo; Hanindyo Kuncarayakti, Millennium Institute of
Astrophysics, Chile; Makoto Watanabe and Hikaru Nakao, Hokkaido University;
and Yoichi Itoh, Kumiko Morihana, Satoshi Honda, Yuhei Takagi, and Jun
Takahashi, University of Hyogo, report that low-resolution optical spectra
(range 400-1000 nm) of 2014ed were obtained on 2014 Nov. 23.82 and 27.73 UT
with the Line Imager and Slit Spectrograph (Hashiba et al. 2014, SPIE 9147, 2)
on the 2.0-m Nayuta telescope at Nishi-Harima Observatory.  Cross-correlation
with a library of supernova spectra via the SNID code (Blondin and Tonry 2007,
Ap.J. 666, 1024) shows a best fit with type-Ia supernovae at z = 0.15 around
or a few days before maximum.
