LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 15.8 ± 0.2) on an unfiltered image taken on Apr. 10.27 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object, which is also present at mag approximately 15.9 ± 0.2 in an image taken on Apr. 11.11, is located at R.A. = 15:56:22.57 ± 0".1, Decl. = -31:32:09.8 ± 0".1 (equinox 2000.0), which is about 5".9 west and 3".4 north of the center of the apparent host galaxy. Nothing is visible at this position on archival images taken on Mar. 19.38 (limiting mag 18.5) and 2009 Aug. 10.99 (limiting mag 18.0).
