Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla GonzalezGlobal SN ProjectSN Ia0.067Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024) we find best fits to SNe Ia around maximum light, including SN 2006gr two days before maximum. The best-fit redshift from SNID is z=0.067. Assuming this redshift, we measure a Si II ejecta velocity of approximately 11,000 km/s. The phase is well-matched by both the ZTF light curve and the Si II velocity.2021TNSCR3736....1P
