We obtained an optical spectrum of ASASSN-15ts (ATel #8380) on UT 2015 December 8.1 with GMOS mounted on the Gemini South telescope. The spectrum of ASASSN-15ts is that of a normal Type Ia at peak. After correcting for the redshift of the host galaxy, we measure a Si II 6355 expansion velocity of -14000 km/s.
