Filippenko (UCB), Jesper Sollerman (Stockholm), Rachel Bruch (Weizmann) None SN Ic 0.027 1 We classify SN 2022lfa as SN Ic using a spectrum obtained on MJD 59755.43 using the 3-m Shane telescope at Lick Observatory. A SNID analysis (Blondin & Tonry 2007, 2007ApJ...666.1024B) shows an excellent match to SN 2004fe at +22 days with redshift 0.027 +/- 0.004. ZTF is a project led by PI S. R.
