Spectra (410-950 nm) of two recent M31 nova candidates, P60- M31-080913 (ATel#1717) and P60-M31-080915 (ATel#1719), were obtained with the 9.2m Hobby-Eberly Telescope (+ Marcario Low-Resolution Spectrograph) approximately 9 and 5 days post discovery on 2008 September 22.4 UT and 20.2 UT, respectively. The spectrum of P60-M31-080913 is dominated by Balmer and Fe II emission features (FWHM H&alpha ~ 1500 km/s) superimposed on a flat continuum, and is typical of an Fe II nova approximately a week post maximum.
