P. Ochner, S. Valenti, S. Benetti, A. Pastorello, and L. Tomasella, Istituto Nazionale di Astrofisica (INAF), Osservatorio Astronomico di Padova; and F. Bufano, INAF, Osservatorio Astronomico di Catania, on behalf of a larger collaboration, report that a spectrum of PSN J07281702-6221189 = SN 2011gw, obtained on Oct. 20.33 UT with the New Technology Telescope (+ EFOSC2; range 360-930 nm; resolution 1.8 nm), shows it to be a type-Ib/c supernova. The best fits to this spectrum found by GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; publicly available at https://gelato.tng.iac.es) are with spectra of type-Ib/c supernovae at about two months post-maximum, after adopting a recessional velocity of 3248 km/s for IC 2200 (Sekiguchi and Wolstencroft 1992, MNRAS 255, 581; via NED).
