Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino Global SN Project SN Ia 0.10196 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 SNe Ia a few days before maximum light. The supernova is closest to WISEA J091847.91+302116.7 (z = 0.101960, 2014ApJS..213...35G, value from NED). Adopting this redshift we measure a Si II 6355 velocity of approximately 10,000 km/s. Adopting the distance modulus computed from this redshift (38.4), the g-band absolute magnitude of the object roughly coeval with the spectrum is -19.4 (apparent magnitude 19.0, from ZTF). This absolute magnitude is consistent with an SN Ia near maximum light. 2020TNSCR3626....1B
