The spectrum resembles that of SN 2009ip (Pastorello et al 2013, ApJ, 767, 1; Fraser et al. 2013, MNRAS, 433, 1312), although we cannot rule out some contamination from the host galaxy background. The EW of the Galactic Na ID component is 1.06, and that of the host 2.23. Scaling from the Galactic extinction (Schlafly & Finkbeiner 2011, ApJ, 737, 103) of A_R = 0.34 mag, suggests a total line-of-sight extinction of A_R ~ 1 mag. This yields an absolute magnitude of M ~ -18.5 mag for ASASSN-17fy.
