The Asiago Transient Classification Program (Tomasella et al. 2014, AN, in press, http://arxiv.org/abs/1403.7233 ) reports the spectroscopic classification of two SNe. Targets were supplied by All Sky Automated Survey for SuperNovae (http://www.astronomy.ohio-state.edu/~assassin/) and the IAU Transient Objects Confirmation Page list (http://www.cbat.eps.harvard.edu/unconf/tocp.html). The observations were performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.3 nm).

(1) The expansion velocity deduced from the Si II 635-nm absorption is about 11400 km/s
(2) The expansion velocity deduced from the Si II 635-nm absorption is about 13400 km/s

Classifications were done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024). The Asiago classification spectra are posted at the website http://sngroup.oapd.inaf.it.
