SUPERNOVA 2011hc
     L. Tomasella, S. Benetti, S. Valenti, A. Pastorello, and M. Fiaschi,
Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on
behalf of a larger collaboration, report that a spectrogram of SN 2011hc (cf.
CBET 2882) was obtained on Oct. 30.74 UT with the Ekar-Copernico 1.82-m
telescope (+ AFOSC; range 380-820 nm; resolution 2.2 nm).  Cross-correlation
with a library of supernova spectra using the "Supernova Identification" code
(SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests a normal type-Ia
supernova at z = 0.037 slightly before maximum.  The expansion velocity, as
deduced from the position of the minimum of the Si II 635.5-nm line,
11000 km/s.
