Svendsen None SN Ia 0.047 1 SNID indicates decent matches with spectra of SN 2006gr and SN 2007F obtained around a week before maximum. Host red-shift of z=0.047 comes from The 6dF Galaxy Survey Data Release 3 (Jones et al. 2009, MNRAS, 399, 683). We note that SNID suggests a host redshift of z=0.022. 2018TNSCR1183....1S
