S. Valenti, A. Pastorello, S. Benetti, L. Tomasella, F. Bufano, and P. Ochner, Istituto Nazionale di Astrofisica, Osservatorio Astronomico di Padova, on behalf of a larger collaboration, report that a spectrogram of PSN J23005471+1850323 = SN 2011ie, obtained on Nov. 20.85 UT with the 1.82-m Copernico Telescope (+ AFOSC; range 340-790 nm, resolution 2.2 nm), shows it to be a type-Ia supernova. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests that 2011ie is similar to SN 1994D at a few days before maximum. Adopting a redshift of z = 0.031, the velocity of the ejected material, deduced from the minimum of the Si II 635-nm line, is about 11300 km/s.
