Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig PellegrinoGlobal SN ProjectSN Ia0.11Global 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 near maximum light. The supernova is closest to WISEA J215512.32-111924.7, and we measure a redshift of approximately 0.11 based on narrow host galaxy lines present in the spectrum. Adopting this redshift we measure a Si II 6355 velocity of approximately 12,000 km/s. Adopting the distance modulus computed from this redshift (38.5), the r-band absolute magnitude of the object roughly coeval with the spectrum is -19.5 (apparent magnitude 19.0, from ZTF). The absolute magnitude and velocities are consistent with an SN Ia near maximum light.2020TNSCR3662....1B
