We obtained a spectrum of ASASSN-17gi/AT 2017ecp (ATel #10398) on 2017 May 20.7 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 Type Ibn SN 2006jc 25 days after maximum light at redshift z=0.02. The spectrum is available on the Transient Name Server.
