S. Valenti, S. Benetti, 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 J00462108-0909277 = SN 2011gg, obtained on Sept. 26.01 UT, suggests that it is 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 one week before the B-band maximum at a redshift z = 0.055. The expansion velocity derived from the Si II 635.5-nm minimum is then about 10500 km/s.
