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 16.7) on an unfiltered image taken on Mar. 24.26 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. CTIO. The new object, which is also present at mag approximately 16.9 in an image taken on Mar. 25.11, is located at R.A. = 13:49:03.23 ± 0".2, Decl. = -28:03:59.6 ± 0.2 (equinox 2000.0), which is about 7".7 west and 44".1 north of center of the presumed host galaxy. Nothing is visible at this position on archival images taken on Jan. 15.29 and Feb. 17.30 (limiting mag 18.5). The variable was designated PSN J13490323-2803596 when posted on the Central Bureau's TOCP webpage and is designated SN 2011bf here based on the spectroscopic report below.
