We report the spectroscopic confirmation of an optical nova candidate in M31 (RA=00:41:40.32, Dec=+41:14:33.5, J2000) discovered by K. Hornoch on 2007 Feb. 3.798 UT. The spectrum was taken using the Russian 6 m telescope and SCORPIO spectral camera on 2007 Feb. 13.674 UT. The spectrum covers the range 340-760 nm, resolution 1.3 nm. The spectrum shows strong Balmer emission lines (H_alpha FWHM=1760 km/s), FeII emission lines, and possibly weak He and N lines.
