S. Kochanek, B. J. Shappee, K. Z. Stanek, J. Jencson, U. Basu, and J. F. Beacom, Ohio State University; J. L. Prieto, Princeton University; D. Szczygiel and G. Pojmanski, (Warsaw University Observatory; and M. Dubberley, M. Elphick, S. Foale, E. Hawkins, D. Mullens, W. Rosing, R. Ross, and Z. Walker, Las Cumbres Observatory, report their discovery of an apparent supernova (magnitude V = 15.2) on two images obtained on June 17.61 UT during the ongoing All-Sky Automated Survey for SuperNovae (ASAS-SN) using data from the double 14-cm "Brutus" telescope at Haleakala, HI. The new object is located at R.A. = 1h18m41s.76, Decl. = -7d26'39".7 (equinox 2000.0), which is approximately 23" northwest of the face-on spiral galaxy PGC 4701. Nothing is visible at this position in the last prior image from Feb. 4 (V > 17) or on earlier images. Discovery images have been posted at the following website URL: http://www.astronomy.ohio-state.edu/~assassin/followup/ASASSN-13ar.jpeg. David Sand, Texas Tech University, reports on spectroscopy of 2013dl obtained on June 21.80 UT with the FLOYDS spectrograph at the "Faulkes Telescope South" at Siding Spring, showing that 2013dl is a type-Ia supernova within a couple days of maximum light, with a redshift consistent with the apparent host galaxy, which is at z = 0.01775 (Da Costa et al. 1998, A.J. 116, 1). Classification was performed via the SNID cross-correlation software package.
