F. Ciabattari and E. Mazzoni, Borgo a Mozzano, Italy, report the discovery of a possible supernova (mag 17.6) on unfiltered CCD images (limiting mag 18.8) obtained on Aug. 30.05 UT with a 0.5-m Newtonian telescope in the course of the Italian Supernovae Search Project. The new object is located at R.A. = 00:17:59.56, Decl. = +24:33:46.0 (equinox 2000.0; astrometry with respect to UCAC-2 stars), which is 3" west of the center of the galaxy PGC 1170. Nothing is visible at this position on digitized plates of the Palomar Sky Survey from 1952 Aug. 22 (F plate; limiting magnitude 20.3) and 1993 Sept. 15 (J plate; limiting magnitude 20.3). The variable was designated PSN J00175956+2433460 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011fx based on the spectroscopic report below. Additional unfiltered CCD magnitudes for 2011fx: Aug. 30.94, 17.5 (Ciabattari and Mazzoni; limiting mag 19.4); 31.18, 17.5 (R. A.
