Andrew Howell, Iair Arcavi, Curtis McCullyGlobal SN ProjectSN Ia-91bg-like0.0054Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several 91bg-like Type Ia supernovae before maximum light at the redshift of the proposed host galaxy (z=0.0054; De Vaucouleurs et al. 1991, "Third Reference Catalog of Bright Galaxies" via NED).
