We obtained optical spectra (range 360-920 nm) of ASASSN-15fk (ATel #7259) and ASASSN-15hh (ATel #7419) on UT Apr 23.0 with WFCCD mounted on the du Pont 2.5m telescope at LCO. Cross-correlation with a library of SN spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows that ASASSN-15fk is a Type Ia at +30 days and ASASSN-15hh is a normal Type Ia at -2 days (best fit template is SN 2007jg). After correcting the spectrum of ASASSN-15hh for the redshift of its host galaxy we measure a Si II 635.5nm expansion velocity of -11700 km/s.
