V. Stanishev, Centro Multidisciplinar de Astrofisica, Instituto Superior Tecnico, Lisbon; M. Stritzinger, Aarhus University; and R. Amanullah and A. Goobar, Stockholm University, report that a spectrogram of PSN J19213020+6108101 = SN 2012bv, obtained on Apr. 10.18 UT by D. Oszkiewicz and S. Geier with the Nordic Optical Telescope (+ ALFOSC; range 330-910 nm), shows it to be a type-II supernova soon after explosion. The spectrum consists of a blue continuum superimposed with weak P-Cyg hydrogen Balmer lines. Adopting for the host galaxy, NGC 6796, a recession velocity of 2189 km/s (Theureau et al. 1998, A.Ap. Suppl. 130, 333), the absorption component of H_alpha is found to be blue-shifted by roughly 9100 km/s.
