F. Ciabattari, S. Donati, G. Petroni, M. Rossi, and R. Simonetti, Borgo a Mozzano, Italy, report their discovery of an apparent supernova on unfiltered CCD images (limiting mag > 19.0) obtained on Aug. 22.08 (at mag 18.1 ) and 24.01 UT (when at mag 18.0) with a 0.5-m Newtonian telescope in the course of the Italian Supernovae Search Project. The new object is located at R.A. = 0:47:19.93, Decl. = +27:49:35.5 (equinox 2000.0; astrometry with respect to UCAC-2 stars), which is 18" east and 5" south of the center of the galaxy IC 1584. Nothing is visible at this position on their images from Sept. and Dec. 2010 (limiting mag 18.8) or on digitized Palomar Sky Survey plates from 1987 Aug. 21 (J plate, limiting mag 20.3) and 1990 Oct. 24 (limiting mag 20.3). The variable was designated PSN J00471993+2749355 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011fl based on the spectroscopic report below.
