We report that optical spectroscopy (range 340-820 nm; resolution 1.3 nm) obtained on Nov. 8.18 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC), shows that PSN J13144705+5405055 (= MASTER OT J131447.05+540505.5) is a type-Ia SN at a redshift z~0.033 (Sloan Digital Sky Survey Data Release 3). The best match was found with type-Ia SN 2002bo (Benetti et al. 2004, MNRAS, 348, 261) about 3-4 weeks after the B band maximum light. The Asiago classification spectra are posted at this website: URL http://graspa.oapd.inaf.it ; classification was made via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
