We report optical spectroscopic observations of two ASAS-SN transients, ASASSN-18ag/AT2018ds and ASASSN-18aj/AT2018dx, obtained on UT 2018 Jan 11 with FAST (range 3600-7450 Angstroms) mounted on the F. L. Whipple Observatory 1.5-m telescope. Both transients are normal SN Ia around peak brightness. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type, phase and redshift determination. ASASSN-18aj has a SN redshift of z=0.053 +/- 0.004.
