Craig Pellegrino (UCSB/LCO), Yael Dgany (TAU), Iair Arcavi, Jamison Burke (UCSB/LCO), D. Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Giacomo Terreran report/s a classification of object: SN 2022cox

Type: SN Ia
Redshift: 0.087

Remarks: Using Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024) we find best fits to normal SNe Ia several days before maximum light. We measure a redshift of z=0.087 from host galaxy emission lines in the spectrum. Assuming this redshift, the SI II absorption velocity is approximately 11,500 km/s. The ZTF g-band magnitude roughly coeval with the spectrum is 18.4 (-19.4), consistent with a SN Ia around maximum light.

The following Classification spectrum was provided:
