We obtained a spectrum of ASASSN-17mh/AT 2017guh on 2017 September 19.7 UT with the robotic FLOYDS instrument mounted on the Las Cumbres Observatory 2-meter telescope in Siding Spring, Australia. Using Superfit (Howell et al. 2005, ApJ, 634, 1190), we find a good fit to the normal Type Ia SN 1989B 7 days before maximum light at the redshift of the proposed host galaxy (z=0.015; Longhetti et al. 1998, A&AS, 130, 267 via NED). The spectrum is available on the Transient Name Server.
