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 Apr. 29 with the New Technology Telescope (+ EFOSC2), show that PSN J20522510-0546156 = SN 2012ga is a type-II supernova at redshift z = 0.020; the spectrum is similar to those of a few type-II supernovae at two weeks 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).
