On 2013 June 27 UT, we use the Dual Imaging spectrograph mounted on the ARC 3.5m telescope at Apache Point Observatory to obtain a spectrum of a recent M31 nova (ATel #5157). Its spectrum shows weak continuum superposed by strong emission lines, such as Balmer series, OI 7773, OI 8447, OI 9266, Ca II IR triplet and Fe bands between 5000 and 5500 Angstrom. The FWHM of Halpha is about 1500 km/s. This spectrum confirms it as a Fe II nova in M31.
