We obtained optical spectra (range 360-950 nm) of ASASSN-15kn/PSNJ12415045-0710122 (ATel #7602) and ASASSN-15kg (ATel #7608) on UT June 10.02 with the Magellan Baade 6.5-m telescope (+ IMACS). Both objects are Type Ia SNe around maximum light. Cross-correlation with a library of SN spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows that ASASSN-15kn/PSNJ12415045-0710122 is a normal Type Ia SN at +2 days and ASASSN-15kg is a normal Type Ia at -3 days. After correcting the spectra for the redshift of their host galaxies, we measure a Si II 635.5nm expansion velocity of approximately -10000 km/s and -11000 km/s for ASASSN-15kn and ASASSN-15kg, respectively.
