Reichart, K. Ivarsen, J. Haislip, A. Crain, D. Foster, M. Nysewander, and A. 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 17.2) on an unfiltered image taken on Jan. 5.32 UT with the 0.41-m 'PROMPT 4' telescope located at Cerro Tololo. The new object is located at R.A. = 14:21:14.21 ± 0".2, Decl. = -36:13:10.7 ± 0".2 (equinox 2000.0), which is about 16".4 west and 25".0 north of the center of the galaxy ESO 385-12. The variable was designated PSN J14211421-3613107 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012R based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012R (unfiltered unless noted otherwise): 2010 Jan. 22.34-2011 June 11.08, [20.0 (CHASE; stack of eleven 80-s images); 2011 June 11.08, [18.5 (CHASE); 2012 Jan. 7.30, 17.1 (CHASE); 11.753, R = 18.2 (Joseph Brimacombe, Cairns, Australia; 44-cm telescope + U16 camera + red filter; position end figures 14s.24, 10".6). An image taken by Brimacombe on 2012 Jan. 8.769 with a 41-cm RCOS telescope (+ STL6K camera + infrared filter; range > 700 nm) yields position end figures 14s.25, 10".8; his image is posted at http://www.flickr.com/photos/43846774@N02/6663127901/.
