Schulze (OKC Stockholm), S. Dhawan (KICC Cambridge) None SN Ia 0.14 1 2 adH0cc An optical spectrum of SN 2022ccz, obtained on UT 2022 February 23.1 with the 3.58m Italian Telescopio Nazionale Galileo (Canary Islands, Spain) and DOLORES, resembles those of Type Ia supernovae a few days before B-band maximum. GELATO (Harutyunyan et al. 2008) provides good matches with normal and 91T-like Type Ia supernovae between -8 and -2 days. We favour a phase close to peak based on the almost flat ZTF light curve. We have adopted the host redshift for the supernova. 2022TNSCR.510....1T
