Abstract (from CDS):

E. Cappellaro, A. Pastorello, L. Tomasella, S. Benetti, M. Fiaschi, P. Ochner, M. Turatto, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrogram of PSN J12504523-1416085 = SN 2012bo, obtained on Mar. 28.97 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 2.4 nm), suggests that it is a type-Ia supernova. Adopting for the host galaxy (NGC 4726) a redshift z = 0.0254 (Jones et al. 2009, "6DF Galaxy Survey Data Release 3"; via the NED database), a comparison with a library of supernovae spectra via GELATO (Harutyuyan et al. 2008, A.Ap. 488, 383) indicates that 2012bo is similar to SN 2003du (Stanishev et al. 2007, A.Ap. 469, 645) around one week before B-band maximum light. The expansion velocity deduced from the Si II 635.5-nm minimum is about 10700 km/s.
