L. Tomasella, A. Pastorello, S. Valenti, and S. Benetti, Istituto Nazionale di Astrofisica (INAF), Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram of 2011hf, obtained on Oct. 29.84 UT with the Ekar-Copernico 1.82-m telescope (+ AFOSC; range 360-810 nm; resolution 2.2 nm), is that of a type-Ia supernova at a redshift 0.054. 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 about 10 after its B-band maximum brightness.
