L. Tomasella, S. Benetti, E. Cappellaro, A. Pastorello, P. Ochner, M. Turatto, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrum (range 360-810 nm; resolution 2.3 nm) of 2012br was obtained on Apr. 1.06 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC). The spectrum shows that 2012br is a type-II supernova with strong Balmer lines – in particular, a broad H_alpha emission with FWHM corresponding to about 11000 km/s. Cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) returns a best fit with the type-IIP supernova 2004et soon after explosion and a redshift z = 0.019.
