Otherwise, the redshift is determined from the host galaxy. We measure a redshift of 0.0713 from a spectrum of the host galaxy, which differs from the NED-listed redshift that was inferred from a friends-of-friends procedure. The spectrum matches well with SN 1991bg-like SNe Ia at a phase of about 18 days after peak at a redshift of 0.07, consistent with our spectroscopic redshift measurement. We measure a Si II 6355 velocity of -8,100 km/s. 2025TNSCR2130....1K
