SUPERNOVA 2013ba
     Emiko Matsumoto and Nozomu Tominaga, Konan University; Masaomi Tanaka,
National Astronomical Observatory of Japan; Eric Hsiao, Carlos Contreras,
Consuelo Gonzalez, Nidia Morrell, and Mark Phillips, Las Campanas Observatory;
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 19.9) on a g-band CCD image (limiting mag 20.7) taken
on Apr. 4.65 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. = 13h52m56s.63, Decl. = +21d56'21".7 (equinox
2000.0), which is 0".7 east and 0".8 north of a possible host galaxy
(SDSS J135256.58+215620.9).  Nothing is seen at this position in images taken
on Mar. 10.75 (limiting mag 19.5) and Mar. 8.78 (limiting mag 20.4).  The
variable was confirmed with the Swope 1-m telescope at Las Campanas
Observatory.

     M. Stritzinger, Department of Physics and Astronomy, Aarhus University;
and F. Taddia, Oskar Klein Centre, Stockholm University, on behalf of the
KISS collaboration and the Carnegie Supernova Project, report that they
obtained a visual-wavelength spectrogram of 2013ba on Apr. 7.2 UT with the
Nordic Optical Telescope (+ Alfosc).  The spectrum reveals the transient to
be a normal type-Ia supernova at or around maximum light.
