GIANCARLO CORTINI (Monte Maggiore Observatory-Predappio-ITALY) reports the discovery of a possible supernova in NGC 5339 by 0.35m. Sch.-Cass.F/5.5 + SXVR-H9 CCD camera on several unfiltered images taken on: 2013/03/03.141; 90sec.exposure,mag.+14.7,limit mag. about+19.5; the new object is located at: R.A. 13 54 00.683, DECL. -07 55 43.77(2000.0) wich is : 8 arcsec N and 5.7 arcsec E from the centre of the parent galaxy. My past images of the same field taken on 2012/05/17.90 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.
