Spectra (range 350-760 nm) of supernova ASASSN-15lf (ATEL 7634) and ASASSN-15lg (ATEL 7635) were obtained on June 16, 2015 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates the spectrum of ASASSN-15lf is a IIn at early phase. The spectrum of ASASSN-15lg matches best with normal Type Ia sn2003du at a phase of -10 days before max.
