We obtained a spectrum of ASASSN-17en/AT 2017cxy (ATel #10255) on 2017 April 14.7 UT with the robotic FLOYDS instrument mounted on the Las Cumbres Observatory 2-meter telescope in Siding Spring, Australia. Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find a good fit to the normal Type Ia SN 2002de 2 days after maximum light at a redshift of z=0.021, which is consistent with that of the proposed host galaxy (z=0.020; di Nella et al. 1996, A&AS, 118, 311 via NED). The spectrum is available on the Transient Name Server.
