Jamison Burke (LCO/UCSB), Yael Dgani (TAU), Iair Arcavi, Daichi Hiramatsu (LCO/UCSB), D. Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino report/s a classification of object: SN 2020aazy

Type: SN Ia
Redshift: 0.09

Remarks: Using 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 J234828.48-052344.3, and we measure a redshift of approximately 0.09 based on narrow host galaxy lines present in the spectrum. Adopting this redshift we measure a Si II 6355 velocity of approximately 13,000 km/s. Adopting the distance modulus computed from this redshift (38.1), the r-band absolute magnitude of the object roughly coeval with the spectrum is -19.5 (apparent magnitude 18.6, from ZTF). The absolute magnitude and velocities are consistent with an SN Ia near maximum light.
