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 16.8) on an unfiltered image taken on Mar. 25.34 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. The new object is located at R.A. = 13:54:51.69 ± 0".2, Decl. = -26:30:46.4 ± 0".2 (equinox 2000), which is about 8".2 west and 3".6 north of the center of the presumed host galaxy. The variable was designated PSN J13545169-2630464 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012bk based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012bk: Feb. 4.29-Mar. 7.15, [19.5 (CHASE; eight stacked 40-s images); Mar. 14.27, [18.0 (CHASE); 26.25, 16.0 (CHASE); 27.415, 17.3 (Joseph Brimacombe, Cairns, Australia; remotely using a 51-cm RCOS telescope + STL11K camera + luminance filter at the New Mexico Skies Observatory near Mayhill, NM, U.S.A.; position end figures 51s.68, 46"; image posted at website URL http://www.flickr.com/photos/43846774@N02/7023051949/).
