The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of PSN J06280368+7418338 in the galaxy UGC 3460, discovered by P. Campaner (ISSP). Information on these transients are also available from the "Bright Supernova" website (http://www.rochesterastronomy.org/snimages/) and the CBAT Transient Object Followup Reports (http://www.cbat.eps.harvard.edu/index.html). The observations were performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm).

(1) The spectrum shows P-Cygni Lines of H, Fe II and Na I typically observed in Type II SNe during the H recombination phase. From the minimum of Halpha, we infer an ejecta velocity of about 6200 km/s (slightly lower, about 5100 km/s, from the minimum of Hbeta). The redshift is from RC3, via NED.
The classification was done with SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
