Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig PellegrinoGlobal SN ProjectSN Ia0.045Global 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 ~10 days after maximum light, including the peculiar SN 2007if 10 days after peak. This phase is consistent with the ZTF lightcurve. The supernova is closest to WISEA J014746.49-214540.3, and we measure a redshift of approximately 0.045 based on narrow host galaxy lines present in the spectrum. Adopting this redshift we measure a Si II 6355 velocity of approximately 9000 km/s. Adopting the distance modulus computed from this redshift (36.5), the r-band absolute magnitude of the object roughly coeval with the spectrum is -18.1 (apparent magnitude 18.4).2020TNSCR3823....1B
