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 16.0 ± 0.4) on unfiltered images taken on May 10.99 and 11.99 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object is located at R.A. = 10:14:50.93 ± 0".2, Decl. = -43:37:48.8 ± 0".2 (equinox 2000.0), which is about 69".8 west and 40".2 south of the center of the galaxy ESO 263-23. Nothing is visible at this position on archival images taken on May 4.01 (limiting mag 18.5) and in a stack of thirteen 80-s images taken between 2011 Apr. 1.14 and 2012 May 4.01 (limiting mag 20.5). The variable was designated PSN J10145093-4337488 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012cl based on the spectroscopic confirmation reported below.
