The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification of PSN J00574018+4347342. Target was supplied by the IAU Transient Objects Confirmation Page list (http://www.cbat.eps.harvard.edu/unconf/tocp.html). The observation was performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.3 nm).

(1) The recessional velocity is from Strauss et al. 1992, ApJS 83, 29; similar to type-Ic supernova 2007gr (Valenti et al. 2008, ApJ 673, L155)

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.
