Thomas G. Brink (UCB), Kishore C. Patra (UCB), Alexei V. Filippenko (UCB), Jesper Sollerman (Stockholm), Rachel Bruch (Weizmann) report/s a classification of object: SN 2022lfa

Type: SN Ic
Redshift: 0.027

Remarks: 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. Kulkarni at Caltech, and includes IPAC; WIS, Israel; OKC, Sweden; JSI/UMd, USA; UW,USA; DESY, Germany; NRC, Taiwan; UW Milwaukee, USA and LANL USA.
