M. Childress, G. Zhou, B. Tucker, D. Bayliss, R. Scalzo, F. Yuan, and B. Schmidt, Australian National University (ANU), write that they obtained a spectrogram (range 360-1000 nm at 0.1-nm resolution) of PSN J03333599-3607377 = SN 2012fr on Oct. 28.533 UT with the Wide Field Spectrograph (WiFeS; cf. Dopita et al. 2007, Ap. Space Sci. 10, 255) on the ANU 2.3-m telescope at Siding Spring Observatory. The object displays clear signatures of a young type-Ia supernova, including the Si 635.5-nm line observed at 591.0 nm (22000 km/s), and a broad high-velocity Ca infrared triplet observed at 770.0 nm. The object's spectrum was compared to supernova spectral templates using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), and the best type-Ia supernova match was to the spectrum of SN 2003W at -11 days and redshift z = 0.
