L. Tomasella, E. Cappellaro, P. Ochner, S. Benetti, A. Pastorello, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrum (range 360-810 nm; resolution 2.2 nm) of 2012K was obtained on Jan. 17.75 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC). The spectrum is dominated by broad Balmer emissions typical of a normal type-II supernova shortly after maximum. While H_alpha shows only a broad emission component, H_beta has a well-developed P-Cyg profile. Adopting a recession velocity of 6086 km/s (de Vaucouleurs et al. 1991, RC3 catalogue; via NED) for the parent galaxy, the absorption minimum corresponds to an expansion velocity of 10500 km/s.
