Andrew Howell, Curtis McCully, Estefania Padilla GonzalezGlobal SN ProjectSN Ia0.06Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024) we find best fits to young SNe Ia, including SN 2003W about a week before maximum. This phase estimate broadly matches that derived from the ZTF light curve. Assuming the best fit redshift from SNID of z = 0.06 we measure a speed of 13,000 km/s for the Si II 6355 line.2021TNSCR1046....1P
