We obtained a spectrum of dlt17aw/AT 2017drh (ATel #10343) on 2017 May 3.57 UT with the robotic FLOYDS instrument mounted on the Las Cumbres Observatory 2-meter telescope in Haleakala, Hawaii. Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find a good fit to the Type Ia SN 2004eo at 2 weeks before maximum light. The spectrum is red suggesting that the SN is highly extinguished. The spectrum is available on the Transient Name Server
