Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.031275Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190), we find a good fit to the normal Type Ia SN 1994D 8 days before maximum light at the redshift of proposed host galaxy (z=0.031; Huchra et al. 2012, ApJS, 199, 26 via NED).
