Pastorello, Dipartimento di Astronomia, Universita di Padova, on behalf of a larger collaboration, report that a spectrogram of PSN J00204598+0656052 = = SN 2011gr, obtained by the Service Telescope Operator Team on Sept. 28.8 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC; range 360-810 nm; resolution 2.2 nm), is that of a type-Ia supernova. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests a normal type-Ia supernova about three weeks after its B-band maximum at a redshift z = 0.07. The expansion velocity derived from the Si II 635.5-nm minimum is then about 9000 km/s.
