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 17.6) on unfiltered images taken on Mar. 21.34 and 23.36 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. The new object (which was designated PSN J18593846-4145558 when posted on the Central Bureau's TOCP webpage and is here designated SN 2011bo based on the spectroscopic report below) is located at R.A. = 18:59:38.46 ± 0".2, Decl. = -41:45:55.8 ± 0".2 (equinox 2000.0), which is about 8".1 west and 9".3 south of center of the galaxy ESO 337-6. Nothing is visible at this position on archival images taken prior to this year (limiting mag 18.5).
