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 16.6) on an unfiltered image taken on Aug. 28.09 UT with the 0.41-m 'PROMPT 5' telescope located at Cerro Tololo. The new object, which is also present at mag approximately 16.1 in an image taken on Aug. 29.04, is located at R.A. = 20:13:55.16 ± 0".2, Decl. = -1:09:22.2 ± 0".2 (equinox 2000.0), which is about 11".3 east and 4".9 north of center of the galaxy UGC 11527. Nothing is visible at this position on archival images taken on Aug. 24.99 (limiting mag 18.0) and Aug. 12.01 (limiting mag 18.5). The variable was designated PSN J20135516-0109222 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011fj based on the spectroscopic report below.
