Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.0632Global 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 the host galaxy (z=0.0632; Strauss & Huchra 1988, AJ, 95, 1602 via NED).
