We obtained a spectrum of nova candidate M33N 2015-12b (PNV J01335420+3026108; see CBAT TOCP) with the SPRAT spectrograph on the 2m Liverpool Telescope (Steele et al. 2004) on 2016 January 4.81 UT.
The spectrum shows strong Balmer emission and numerous Fe II lines (including multiplets 27, 28 and 42). Na I (D) and O I (7773 Å) emission lines are also present. This spectrum confirms that M33N 2015-12b is a classical nova eruption in M33 and a member of the Fe II spectroscopic class.
