We obtained a spectrum of the candidate supernova ASASSN-17dj/AT 2017cav (ATEL #10155) with the SPRAT spectrograph mounted on the robotic 2m Liverpool Telescope at the Roque de los Muchachos observatory (La Palma). Observations started on 2017 Mar 10.18 (UT). The spectral range is 400-800 nm and the dispersion is 9.2 Angstrom/pixel.
Classification with SNID (Blondin and Tonry 2007, ApJ, 666, 1024) indicates that this is a type Ia supernova near maximum light at a redshift around 0.025. The best fit is with SN 2005el 2 days past maximum light, at a redshift z=0.022.
The spectrum is available on the Transient Name Server.
