Benetti, Instituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that optical spectra (range 380-820 nm; resolution 1.1 nm) of PSN J13341470+3712348 = SN 2011bl were obtained with the Ekar-Copernicus 1.82-m telescope (+ AFOSC) on Apr. 11.1 UT. After cross-correlation with a library of supernova spectra via the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383; available at website URL https://gelato.tng.iac.es/login.cgi), 2011bl is identified as a very young type-Ib/c supernova, around 10 days before maximum.
