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. 6.07 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 1.3 nm), shows that 2012gg is a type-II supernova about one month after explosion at redshift, z, about 0.03. For the estimated epoch, a high ejecta-expansion velocity of about 9500 km/s is derived from the minimum of the broad, P-Cyg-profile H-alpha line. 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).
