ASASSN-18fs was recently discovered as a possible Galactic nova (ATel #11442). We obtained a spectrum of ASASSN-18fs with the Du Pont 2.5m telescope at Las Campanas Observatory on UT 2018 Mar 20. The spectrum shows broad H-alpha and HeII 4686 emission and broad absorption in Hbeta and higher-order Balmer lines. These features are consistent with a dwarf nova outburst, and we classify this source as a cataclysmic variable rather than a classical nova.
