Simone Leonini, Siena, Italy, report the pre-discovery by S. Leonini, G. Guerrini, P. Rosi and L.M. Tinjaca Ramirez of the supernova in UGC09396 (mag. about +17.4CR – USNO A2 catalogue) on unfiltered CCD image (limiting mag. about +19.0) taken on 2012 January 18.15138 UT at the Montarrenti Observatory in the course of an automatic survey of the Italian Supernovae Search Project using a 0.53m f/8.7 Ritchey-Chretien telescope (+ Apogee Alta U47 CCD camera). The new object is located at R.A. 14h35m44.68s, Decl. +24degrees43arcmin41.7arcsec. - equinox 2000.0). No stellar source is visible at the position of the apparent supernova in our past images including one on 2011 May 25 (limiting mag. about +19.0) and it does not appear on Palomar Sky Survey infrared, red and blue plates (1992 Jun 05, F plate; 1994 Mar 08, J and N plate; limiting mag. +19.5). No known minor planets are marked in that position for the time of our observation.
