Benitez-Herrera, Max-Planck-Institute fuer Astrophysik, Garching, on behalf of the PESSTO collaboration (see Valenti et al., posted at website URL http://www.astronomerstelegram.org/?read=4037), report that optical spectroscopy (range 360-910 nm), obtained on Aug. 7 with the New Technology Telescope (+ EFOSC2), show that PSN J20032484-5557192 = SN 2012fz is a type-Ia supernova at redshift z = 0.017; the best fit is to the spectrum of SN 2003du at 33 days past explosion. PESSTO classification spectra can be obtained from website URL http://www.pessto.org/; classification is made via SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) and GELATO (Harutyunyan et al. 2008, A.Ap. 488, 383).
