DongASAS-SNSN Ia0.019804ASAS-SNThe best match for the spectrum of 2017dei/Gaia17bat is found with Type Ia supernova SN 2004gs (at t=+4day). The spectrum also matches with a number of normal SNe Ia, few days after maximum (1-8 days). SNID estimated redshift is also found to be consistent with the host redshift of ESO 529- G 005 (z=0.019804, NED).
