Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.0435Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several Type Ia supernovae about a month after the maximum light around the redshift of 0.0435 which was deduced from the narrow hydrogen line of the host galaxy. At the redshift of 0.0435, the absolute magnitude at the discovery was ~ -19 mag which is consistent with the Ia classification and its phase.
