Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.02377Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find several good fits to normal Type Ia SNe around a week before maximum light at the redshift of the proposed host galaxy (z=0.024; Jones et al. 2009, "The 6dF Galaxy Survey Data Release 3," via NED). The narrow H_alpha line is likely to be host contamination.
