We report that an optical spectrogram of PSN J08343332-0232361 (range 330-790 nm;
resolution 0.9 nm), obtained on Apr 17.79 UT with the Asiago 1.22-m Galileo
Telescope equipped with the B&C spectrograph, shows it to be a type-Ia supernova.
Adopting for the host galaxy NGC 2615 a redshift z = 0.014 (Theureau et al. 1998,
A&AS 130, 333), an excellent match is found with the type-Ia supernova 2003du
(Stanishev et al. 2007, A&A 469, 645) about 10 days before the B-band maximum light.
An expansion velocity of about 11600 km/s is derived from the position of the minimum
of the Si II 635-nm line. The Asiago classification spectra are posted at URL http://sngroup.oapd.inaf.it. Classification was made via GELATO (Harutyunyan et al.
2008, A.Ap. 488, 383) and SNID (Blondin and Tonry 2007, Ap.J. 666, 1024).
