A spectrum of the recent nova candidate M31N 2011-06d (= PNV J00430685+4115308 on CBAT/TOCP; H-alpha reported in ATEL#3486, ATEL# 3499) was obtained on July 26 with the Double Spectrograph mounted on the Palomar 200-inch Hale telescope. The phase of the transient was about 18 days after its maximum light. The spectrum exhibits prominent Balmer emission lines (FWHM Halpha ~ 1,700 km/s), OI 8446 and 7773 lines as well as Fe II emission lines. This confirms that M31N 2011-06d is a classical nova and a member of the Fe II spectroscopic class. This nova is internally designated as PTF11hfs.
