Abstract (from CDS):

L. Tomasella, S. Benetti, E. Cappellaro, A. Pastorello, M. Turatto, and M. Fiaschi, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that optical spectroscopy (range 340-820 nm; resolution 1.3 nm), obtained on Nov. 6.02 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC range 350-820 nm, resolution 1.3nm), indicates that PSN J01514770+2116206 = SN 2012gd is a type-Ia supernova about ten days after maximum light at redshift z about 0.055. The expansion velocity, as deduced from the position of the Si II 635.5-nm absorption, is about 10000 km/s. The Asiago classification spectra are posted at the following website URL http://graspa.oapd.inaf.it; classification was made via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
