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 17.8) on an unfiltered image taken on Apr. 22.40 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object is located at R.A. = 20:52:25.10 ± 0".2, Decl. = -5:46:15.6 ± 0".2 (equinox 2000.0), which is about 13".9 west and 4".8 north of the center of the galaxy NGC 6976. Nothing is visible at this position on a stack of fifteen 40-s archival images taken between 2011 Apr. 14.36 and 2012 Apr. 1.39 (limiting mag 20.5). The variable was designated PSN J20522510-0546156 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012ga based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012ga: Apr. 15.35, [18.0 (CHASE); 23.38, 17.5 (CHASE); 28.431, 18.9 (J. Brimacombe, Cairns, Australia; obtained 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 25s.12, 16".1; image posted at http://www.flickr.com/photos/43846774@N02/7122722421/).
