Alessandro Dimai, Cortina d'Ampezzo, Italy, reports the discovery by Raffaele Belligoli and Flavio Castellani of an apparent supernova (mag about 16.7) on two unfiltered CCD images (limiting mag about 18.0) taken with the 0.4-m f/8 Ritchey-Chretien telescope of the Monte Baldo Observatory (Ferrara di Monte Baldo, Italy), on Oct. 21.903 UT. The new object is located at R.A. = 6:56:13.39, Decl. +84:04:50.2 (equinox 2000.0), which is 5" east and 6" north of the nucleus of the galaxy UGC 3528. Nothing is visible at this position on Palomar Sky Survey infrared, red, and blue plates. An animation of the variable covering Oct. 21-24 is posted at the following website URL: http://www.astrofiliveronesi.it/uploads/file/UGC3528_RIF_1021_1023_1024.gif. The variable was designated PSN J06561339+8404502 when it was posted at the Central Bureau's TOCP webpage and is here designated SN 2012fm based on the spectroscopic confirmation reported below. Additional CCD magnitudes for 2012fm (unfiltered unless noted otherwise): Aug. 20.773, Sept. 30.815, and Oct. 10.843 UT, [18.2 (D. Denisenko, E. Gorbovskoy, V. Lipunov, V. Yurkov, E. Sinyakov, S.
