Schuldt, Vogl, Taubenberger, Fiore, Benetti, Cappellaro, Tomasella, Turatto report/s a classification of object: SN 2019bjw

Type: SN Ia
Redshift: 0.03005

Remarks: Spectrum similar to several type Ia SNe, about one week before maximum light. We also note that a narrow Na I doublet feature is observed in absorption at the host galaxy redshift, with EW = 3.2 Ang, suggesting a significant line-of-sight reddening (E(B-V) ~ 0.5 mag).The redshift for the host galaxy is reported in SDSS DR6, 2007 (via NED). Using this redshift, an expansion velocity of about 11300 km/s is derived from the SiII 635.5 nm minimum.
