We report a spectroscopic redshift measurement of the candidate host galaxy of FRB 20220912A, PSO J347.2702+48.7066 (ATel #15679, ATel #15716). We obtained a low-resolution spectrum of this galaxy with the LRIS instrument on the Keck I telescope on 2022 October 19 UTC. A single 300s exposure was conducted. Several emission lines were detected at a redshift of 0.077, including H-alpha, H-beta, and strong lines of [OII], [OIII], [NII], and [SII].
