A. Dimai, Cortina d'Ampezzo, Italy, on behalf of the Italian Supernovae Search Project (ISSP), reports the discovery by Fabio Martinelli, Riccardo Mancini, and Fabio Briganti of an apparent supernova on unfiltered CCD images (limiting mag about 19.0) taken with the 0.35-m telescope of the Montecatini Valdicecina Observatory (Pisa, Italy) on Oct. 14.0299 UT (when the new object was at mag about 18.0) and 14.9319 (when it was at mag about 17.6). The variable is located at R.A. = 23:06:02.80, Decl. = +34:06:36.7 (equinox 2000.0), which is 22" west and 8" north of the nucleus of NGC 7485.
