We obtained a spectrum of ASASSN-15rv (ATel #8211) on 2015 October 29.6 UT with the robotic FLOYDS instrument mounted on the Faulkes Telescope South. Using Superfit (Howell et al. 2005, ApJ, 634, 119) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits both to Type Ia supernovae 1-2 weeks after maximum light and Type Ic supernovae near maximum light at redshifts around z=0.04. At this redshift, the most recent photometry point (October 24.2) in ATel #8211 corresponds to an absolute magnitude of -19.5, favoring the Type Ia classification.
