M. Turatto, S. Benetti, A. Pastorello, L. Tomasella, M. Fiaschi, P. Ochner, E. Cappellaro, and S. Valenti, Osservatorio Astronomico di Padova, Istituto Nazionale di Astrofisica, report that a spectrogram of PSN J17315266+7150120 = SN 2012er, obtained on Aug 21.86 UT with the Asiago 1.82-m Copernico Telescope (+ AFOSC; range 340-820 nm; resolution 1.4nm), shows the typical features of a normal type-Ia supernova. Adopting for the host galaxy (PGC 60437) the redshift z = 0.039694 (Falco et al. 1999, PASP 111, 438; via NED), the best fit with the GELATO (Harutyuyan et al. 2008, A.Ap. 488, 383) library of supernovae spectra is with that of SN 1989B obtained at six days after B-band maximum. The photospheric velocity derived from the Si II doublet is 11000 km/s.
