Abstract (from CDS):

L. Tomasella, S. Benetti, E. Cappellaro, P. Ochner, A. Pastorello, M. Turatto, S. Valenti, and M. Fiaschi, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a low-signal-to-noise spectrogram of 2012fe, obtained on Sept. 28.81 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 360-820 nm; resolution 1.9 nm), suggests that this is a peculiar type-Ia supernova. Adopting a redshift of about 0.05, cross-correlation with a library of supernova spectra via the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), and best fits with the GELATO software tool (Harutyuyan et al. 2008, A.Ap. 488, 383) using a library of supernovae spectra, show that 2012fe is most similar to several peculiar type-Ia (1991T-like) supernovae about fifteen days after maximum.
