Abstract (from CDS):

M. Turatto, M. L. Pumo, S. Vanni, S. Benetti, A. Pastorello, L. Tomasella, P. Ochner, E. Cappellaro, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrogram of PSN J01184597+1459402 = SN 2012ex, obtained on Sept. 18.00 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 1.4 nm), shows very strong He lines that are typical of type-Ib supernovae. Adopting for the host galaxy (UGC 838) the redshift z = 0.0229 (SDSS1; via NED), the best fit with the GELATO tool (Harutyuyan et al. 2008, A.Ap. 488, 383) on a vast library of supernovae spectra is with SN 1999dn (Benetti et al. 2011, MNRAS 411, 2726) at one day before maximum.
