Andrew Howell, Curtis McCully, Craig Pellegrino, Stefano ValentiGlobal SN ProjectSN Ia0.039908Global 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 SNe around three weeks after maximum at the host redshift (0.039908; 20096dF...C...0000J, via NED).
