Andrew Howell (LCO/UCSB), Curtis McCully (LCO/UCSB), Estefania Padilla Gonzalez (LCO/UCSB), Craig Pellegrino (LCO/UCSB)Global SN ProjectSN Ia0.052Global 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, including SN 1999gp at peak and SN 2005de 5 days before peak. The supernova is closest to WISEA J220249.69-134804.8. Adopting the SNID-estimated redshift of z=0.052 we measure a Si II 6355 velocity of approximately 10,000 km/s. Adopting the distance modulus computed from this redshift (36.7), the g-band absolute magnitude of the object roughly coeval with the spectrum is -19.6 (apparent magnitude 17.08, from ZTF). This absolute magnitude and velocity is consistent with an SN Ia near maximum light.2021TNSCR4018....1N
