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 17.7 ± 0.4) on an unfiltered image taken on Apr. 14.34 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object (which was designated PSN J20321290-0843470 when posted at the Central Bureau's TOCP webpage and is here designated SN 2011cd based on the spectroscopic report below) is located at R.A. = 20:32:12.96 ± 0".2, Decl. = -8:43:47.1 ± 0".2 (equinox 2000.0), which is about 2".7 east and 14".3 north of center of the galaxy MCG -02-52-11 (= PGC 64907). Additional CCD magnitudes for 2011cd (unfiltered unless otherwise noted): 2009 Sept. 25.03, [18.5 (CHASE/PROMPT); 2010 Mar. 28.38, [18.5 (CHASE/PROMPT); 2011 Apr. 16.36, 17.4 (CHASE/PROMPT); 20.470, 18.9 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 12s.96, 46".3); 22.779, 18.7 (Brimacombe; red filter; position end figures 12s.95, 46".9).
