2012CBET.3314....2M

N. Morrell, E. Hsiao, C. Contreras, and M. Phillips, Las Campanas Observatory, Carnegie Supernova Project, report that they obtained an optical spectrogram (range 370-960 nm) of PSN J00380175-1351395 = SN 2012gx on Nov. 20.05 UT with the Las Campanas 2.5-m du Pont telescope (+ WFCCD), which shows this to be a type-Ia supernova around 10 days past maximum brightness. Cross-correlation with a library of supernova spectra using the Supernova Identification code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) suggests that 2012gx is a normal type-Ia event at a redshift z = 0.014, with a spectrum very similar to that of SN 2003cg at 9 days past maximum light.
