We obtained an optical spectrum (range 360-950 nm) of ASASSN-15kp (ATel #7604) on UT June 9.03 with the Magellan Baade 6.5-m telescope (+ IMACS). The spectrum is that of a normal Type Ia SN. Cross-correlation with a library of SN spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows that ASASSN-15kp is a normal Type Ia SN at -2 days (there are good correlations with SN Ia one week before maximum). After correcting the spectrum for the redshift of its host galaxy (z=0.0174) we measure a Si II 635.5nm expansion velocity of -11000 km/s.
