We obtained a spectrum of MASTER OT J003831.10-640313.7 (ATel #8596) on 2016 January 29.4 UT with the robotic FLOYDS instrument mounted on the LCOGT 2-meter telescope in Siding Spring, Australia. The spectrum shows narrow Balmer absorption (H-alpha 656.3 nm, H-beta 486.1 nm, H-gamma 434.0 nm) and possibly a He II 468.6 nm emission feature superimposed on a strong blue continuum, consistent with the spectrum of the dwarf nova SS Cygni.
