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 17.4) on an unfiltered image taken on Sept. 15.36 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object, which is also present in an image taken on Sept. 13.38 at mag approximately 17.2, is located at R.A. = 7:28:17.02 ± 0".2, Decl. = -62:21:18.9 ± 0".2 (equinox 2000.0), which is about 3".9 west and 8".0 south of center of the galaxy IC 2200. Nothing is visible at this position on archival images taken on 2010 Dec. 22.16 (limiting mag 18.0) and 2010 Oct. 27.25 (limiting mag 17.5). The variable was designated PSN J07281702-6221189 when it was posted on the Central Bureau's TOCP webpage and is here designated SN 2011gw based on the spectroscopic confirmation reported below.
