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. 5.84 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 350-820 nm; resolution 1.3 nm), shows that PSN J22305042-1411163 = SN 2012gc is a reddened type-II supernova a few days after explosion at redshift z = 0.01679 (de Vaucouleurs et al. 1991, RC3; via NED database). Broad Balmer lines of H are clearly detected (H-alpha has a FWHM of about 11000 km/s). The Asiago classification spectra are posted at 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).
