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 2022ccg

Type: SN Ia
Redshift: 0.07

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 around maximum light. The best-fit redshift from SNID is z=0.070. Assuming this redshift, we measure a SI II absorption velocity of approximately 12,000 km/s. The ZTF r-band magnitude obtained roughly four days before the spectrum is 18.4 (-18.9), consistent with a SN Ia before maximum light.

The following Classification spectrum was provided:
