We have obtained an optical spectrum (range 4300-7500 Angstroms) of ASASSN-14lp (ATel #6795) on UT 2014 Dec 10.8 with the ModSpec Echelle spectrograph mounted on the MDM 2.4m telescope. The spectrum shows features characteristic of Type Ia SN. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to perform cross-correlation with a library of SN spectrum and find that ASASSN-14lp spectrum is most consistent with a normal SN Ia a few days before peak.

Continued observations are encouraged.
