On 2019 December 12, beginning at 01:56:13 UTC, we obtained two consecutive 600 s exposures with the Robert Stobie Spectrograph on the Southern African Large Telescope of the unusual fading transient source ASASSN-V J060000.76-310027.83, reported by Way et al. (ATel #13346). The spectra, which cover the region 3200-7260Å at an average resolution of 5.7Å, look typical of an early K type star, with prominent Mg b and Na D absorption lines, consistent with the T_eff reported by Way et al. No emission lines are seen. We speculate that this could be a long period eclipsing binary, currently in eclipse ingress.
