M. Childress, R. Scalzo, F. Yuan, B. Tucker, and B. Schmidt, Australian National University (ANU), report that they obtained a 20-min spectrogram of PSN J06200624-6457085 = SN 2012gp on Nov. 19.73 UT with the Wide Field Spectrograph (WiFeS; Dopita et al. 2007, Ap. Space Sci. 310, 255; note correction to volume number given in CBET 3277) on the ANU 2.3-m telescope at Siding Spring Observatory using the B3000/R3000 gratings (range 350-980 nm at 0.1-nm resolution. The spectrum was compared to supernova spectral templates using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), and the best match was to the spectrum of the normal type-Ia supernova 2001N at +30 days and redshift z = 0.054 ± 0.005, consistent with the redshift of its apparent host galaxy, PGC 75651 (z = 0.0526, from Smith et al. 2004, A.J. 128, 1558; via NED). Given this redshift, the Si 635.5-nm line is identifiable at rest wavelength 619.0 nm, as well as Fe blends at 517.0 and 435.0 nm rest wavelengths.
