E. Gall, S. Taubenberger, and I. Maurer, Max-Planck-Institut fuer Astrophysik; R. Pakmor, Heidelberger Institut fuer Theoretische Studien; and S. Valenti and S. Benetti, Instituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that an optical spectrogram (range 380-820 nm; resolution 1.1 nm) of PSN J12565389+2222282 = SN 2011bm was obtained with the Ekar-Copernicus 1.82-m telescope (+ AFOSC) on Apr. 11.0 UT. SN 2011bm shows a blue continuum with a narrow H-alpha line that is possibly from the host galaxy. 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), the best match is found to be with type-Ic supernovae close to maximum.
