We obtained a spectrum of DLT17h/AT 2017ahn (ATel #10058) on 2017 February 8.7 UT with the robotic FLOYDS instrument mounted on the Las Cumbres Observatory 2-meter telescope in Siding Spring, Australia. The spectrum is low signal-to-noise but shows a blue continuum with H-alpha and H-beta emission, possibly including a broad component, at the redshift of the host galaxy (z=0.009; HIPASS Catalog via NED). We therefore tentatively classify it as a Type II supernova. The spectrum is available on the Transient Name Server.
