2012CBET.3168....2P

J. T. Parrent and D. A. Howell report that a CCD spectrogram (range 350-900 nm) of PSN J00135630-7001407 = 2012dk, taken with the "Gemini South" telescope on July 1 UT, shows that it is a type-Ia supernova. Using the host-galaxy emission lines, a redshift of z = 0.0137 is inferred. Correcting for this redshift, the minimum of the Si 635.5-nm absorption feature is found to be blue-shifted by about 11200 km/s. Comparisons to other spectra with "Superfit" (Howell et al. 2005, Ap.J. 634, 1190) show similar overlap with SN 1990N at three days post-maximum-light.
