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 spectrogram of PSN J22261454+3412591 = SN 2011hw, obtained on Nov. 19.76 UT with the 1.82-m Copernico Telescope (+ AFOSC; range 340-790 nm, resolution 2.2 nm), shows it to be remarkably similar to the transitional type-IIn/Ibn supernova 2005la (Pastorello et al. 2008, MNRAS 389, 131). The spectrum is very blue and shows prominent H and He I lines in emission. In particular, the most prominent He I lines compete in strength with H_alpha. The FWHM velocity of H_alpha is 2700 km/s, while that of He I 587.6-nm is about 2000 km/s. The redshift deduced from the position of the most important lines is z = 0.023.
