Andrew Howell, Iair Arcavi, Curtis McCullyGlobal SN ProjectSN Ia0.0089Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several normal Type Ia supernovae before or near maximum light at the redshift of the proposed host galaxy (z=0.0089; Lauberts & Valentijn 1989, "The Surface Photometry Catalogue of the ESO-Uppsala Galaxies" via NED).
