A spectrum of the nova candidate M31N 2011-06a (ATEL#3409) was obtained with the Double Beam Spectrograph mounted on the Palomar 200-inch Hale telescope on June 28, 2011, about 20 days after its maximum light. The spectrum exhibits prominent Balmer emission lines (FWHM Halpha ~ 2000 km/s) and Fe II emission lines. This observation confirms that M31N 2011-06a is a classical nova, and a member of the Fe II spectroscopic class (Williams et al. 1994). This nova is internally designated PTF11fvj among collaborators.
