L. Tomasella, S. Valenti, A. Pastorello, M. Fiaschi, and S. Benetti, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a low-S/N spectrogram of PSN J02021338-0605016 = SN 2011hm was obtained on Oct. 30.94 UT with the Ekar- Copernico 1.82-m telescope (+ AFOSC; range 380-820 nm; resolution 2.2 nm). A comparison of the observed spectrum with a library of supernova spectra using the "GELATO" code (Harutyunyan et al. 2008, A.Ap. 488, 383) suggests that 2011hm is a type-II supernova. A broad H_alpha feature with P-Cyg profile is visible, along with a number of Fe II features. From the position of the minimum of the H_alpha absorption, an expansion velocity of the ejecta of about 13000 km/s is deduced.
