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.
