The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of MASTER OT J211223.35+144645.1 (Atel #9174), discovered by MASTER-IAC auto-detection system (Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171)

The observation was performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.4 nm).

(1) Best match with Type Ia SNe around B-band maximum light. The expansion velocity as deduced from the Si-II 635.5nm is about 11000 km/s.

Classification was 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.
