Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Giacomo Terreran Global SN Project SN Ia 0.07 1 1 Global SN Project Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024) we find best fits to normal SNe Ia around maximum light. The best-fit redshift from SNID is z=0.070. Assuming this redshift, we measure a SI II absorption velocity of approximately 12,000 km/s. The ZTF r-band magnitude obtained roughly four days before the spectrum is 18.4 (-18.9), consistent with a SN Ia before maximum light. 2022TNSCR.542....1P
