The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic observation of PSN J02490078+1544058 = SNhunt271. Target was supplied by the CBAT Transient Objects Confirmation Page (TOCP). The observation was performed with the Asiago 1.82 m Copernico Telescope (+AFOSC; range 340-820 nm; resolution 1.2 nm), which was equipped with a new CCD (Andor IKON L936) with higher response both in the UV and in the NIR.

* The red continuum indicates significant reddening. A good match is found with the type-II SN 1999em (Elmhandi et al. 2003, MNRAS 338, 939) 3 days before B-band maximum light and assuming an E(B-V)~0.8 mag. The expansion velocity, as deduced from the minimum of the P-Cyg profile of H_alpha, is around 13400 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
