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 J06555100+4041466 = SN 2011go, obtained on Oct. 1.01 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC), shows that is a type-II supernova with strong H_alpha emission showing a broad and narrow component. Cross-correlation with a library of supernova spectra via the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at URL https://gelato.tng.iac.es/login.cgi), shows resemblance to that of SN 2006gy (Agnoletto et al. 2009, Ap.J. 691, 1348), but because of the slow evolution, the phase cannot be constrained.
