Giancarlo Cortini (Monte Maggiore Observatory-Predappio-ITALY) reports the discovery of a possible supernova in UGC 5609 by 0.35m. Sch.-Cass. F/5.5 + SXVR-H9 CCD camera on several unfiltered images, 90 sec. exposure, mag. about+15.6,limit mag. about+ 19.0; the new object is located at:R.A. 10 24 22.31, DECL.+78 36 23.5(2000.0) wich is:9 arcsec.S and 3 arcsec.W from the centre of the parent galaxy. My past images of the same field taken on :2013/07/04.98 and 2013/06/03.90 showed nothing at that position (limit mag.+19.0) and it doesn't appear on P.O.S.S. II red and blue plates. No known minor planet is marked in that position for the time of the discovery.
