F. Ciabattari, E. Mazzoni, and R. Simonetti, Borgo a Mozzano, Italy, report their discovery of an apparent supernova (mag 17.2) on unfiltered CCD images (limiting mag 19) obtained on Aug. 27.99 and 29.04 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. = 22:14:37.82, Decl. = +32:57:18.7 (equinox 2000.0; astrometry with respect to UCAC-2 stars), which is 9" west and 2" north of the center of the galaxy PGC 68367. The variable was designated PSN J22143782+3257187 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012eo based on the spectroscopic confirmation reported below. Additional magnitudes for 2012eo (via unfiltered CCD unless noted otherwise): 1986 Sept. 30, [20.3 (Palomar Sky Survey, F plate, via Digitized Sky Survey; reported by Ciabattari); 1989 Sept. 7, [20.3 (Palomar Sky Survey, J plate, via DSS; reported by Ciabattari); 2012 Aug. 7, [19.5 (Ciabattari); Aug. 15.60, [18.2 (D.
