F. Ciabattari, S. Donati, and G. Fornaciari, Borgo a Mozzano, Italy, report the discovery of an apparent supernova (mag 17.8) on unfiltered CCD images (limiting mag 19.2) obtained on June 27.87 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. = 18:12:19.24, Decl. = +21:31:15.2 (equinox 2000.0; astrometry with respect to UCAC-2 stars), which is 5" east and 12" north of the center of the presumed host galaxy. Nothing is visible at this position on digitized plates of the Palomar Sky Survey from 1993 Aug. 13 (F plate; limiting magnitude 20.3) and 1995 Aug. 23 (J plate; limiting magnitude 20.3) or on their own images from May 2011 (limiting mag 18.8). The variable was designated PSN J18121900+2131150 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2011gc based on the spectroscopic report below. (Provisional designation PSN J18121913+2131136 was also assigned to this object when an independent discovery by Koichi Itagaki was posted to the TOCP after the posting by Ciabattari et al.)
