S. Valenti, S. Benetti, F. Bufano, L. Tomasella, and P. Ochner, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica; and A. Pastorello, Dipartimento di Astronomia, Universita di Padova, on behalf of a larger collaboration, report that a spectrogram (range 360-810 nm; resolution 2.2 nm) of PSN J01192415+1226171 = SN 2011gj, obtained by the Service Telescope Operator Team on Sept. 27.94 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC), is that of a type-Ia supernova. Cross-correlation with a library of supernova spectra via the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at URL https://gelato.tng.iac.es/login.cgi), suggests a type-Ia supernova about two weeks after the B-band maximum at a redshift of z = 0.047583 (RC3, de Vaucouleurs et al. 1991, via the NED website). The expansion velocity deduced from the Si II 635.5-nm minimum is about 9500 km/s.
