Tominaga, E. Matsumoto, and T. Shibata, Konan University; D. Tsvetkov and N. Pavlyuk, Sternberg Astronomical Institute, Lomonosov Moscow State University; M. Takeishi, Hokkaido, Japan; K. Takahashi, Osaka, Japan; T. Morokuma, Institute of Astronomy, University of Tokyo; and M. Tanaka, National Astronomical Observatory of Japan, on behalf of the Kiso Supernova Survey (KISS) collaboration, report the discovery of an apparent supernova (mag 19.3) on a g-band CCD image (limiting mag 20.0) taken on May 19.66 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. = 16h27m46s.15, Decl. = +41d44'23".7 (equinox 2000.0), which is 3".4 east and 5".0 north of the center of the galaxy SDSS J162745.84+414418.6. The variable ws confirmed in R-band images taken with the 0.7-m telescope at the Sternberg Astronomical Institute on May 20.92. M. Tanaka, N. Ukita, and I. Iwata, National Astronomical Observatory of Japan; N. Tominaga, Konan University; and T. Morokuma, Institute of Astronomy, University of Tokyo, on behalf of the KISS project, report that an optical spectrum of 2014bo was obtained on May 27.5 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 at a few days after maximum.
