S. Valenti, A. Pastorello, S. Benetti, L. Tomasella, F. Bufano, and P. Ochner, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a low-signal-to-noise spectrogram of PSN J10061104+2509015 = SN 2011if, obtained on Nov. 21.12 UT with the 1.82-m Copernico Telescope (+ AFOSC; range 340-790 nm, resolution 2.2 nm), suggests that 2011if is a type-II supernova. The best fit to this spectrum, found using a library of supernova spectra via GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383; available at https://gelato.tng.iac.es/login.cgi), indicates that 2011if is similar to SN 1980K at a phase of a few weeks after maximum.
