Remarks: Simone Leonini report the discovery by S. Leonini, L.M. Tinjaca Ramirez, M. Conti and P. Rosi of a PSN (Mag. 16.50R +-0.06 - UCAC-4 catalogue) in IC1339 at Montarrenti Observatory, Siena, Italy (C88), in the course of Italian Supernovae Search Project using a 0.53m f/8.7 Ritchey-Chretien telescope (+ Apogee Alta U47 CCD camera). No stellar source is visible at the position of the apparent supernova in our past images including one dated 12Th Nov 2016.
