Haislip, J. P. Moore, and A. P. LaCluyze, University of North Carolina at
Chapel Hill, on behalf of the CHASE project (which is part of the Millennium
Center for Supernova Science collaboration), report the discovery of an
apparent supernova (mag approximately 17.8) on an unfiltered image taken on
2013 Nov. 18.32 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro
Tololo.  The new object is located at R.A. = 10h50m59s.27 +/- 0".2, Decl. =
-23o39'29".4 +/- 0".2 (equinox 2000.0), which is about 13".3 east and 2".2
north of the center of the galaxy ESO 501-G102.  The variable was designated
PSN J10505927-2339294 when it was posted at the Central Bureau's TOCP webpage
and is here designated SN 2013hv based on the spectroscopic confirmation
reported below.  Additional CCD magnitudes for 2013hv:  June 22.06, [18.5
(CHASE); Nov. 19.33, 18.0 (CHASE); 26.513, 19.3 (Joseph Brimacombe, remotely

Skies observatory near Mayhill, NM, USA; position end figures 59s.23, 30".7;

     F. Bufano and G. Pignata, Universidad Andres Bello, report that an
optical spectrogram (range 380-900 nm), obtained on 2014 Jan. 14.2 UT at the
SOAR telescope (+ Goodman Spectrograph) at Cerro Pachon, suggests that PSN
J10505927-2339294 = SN 2013hv is a type-Ic supernova.  The best fit to this
spectrum found by GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available
at website URL https://gelato.tng.iac.es/login.cgi) suggests that 2013hv is
similar to SN 1990B (Clocchiatti et al. 2001, Ap.J. 553, 886) at around two
months after maximum (host-galaxy redshift z = 0.01327; Lauberts and Valentijn
1989, *Surface Photometry Catalogue of the ESO-Uppsala Galaxies*; via NED).
