We obtained a spectrum of the transient TCP J00333837+4836022 (see CBAT TOCP) with the SPRAT spectrograph (resolution R ~ 350; Piascik et al. 2014) on the 2-m Liverpool Telescope (Steele et al. 2004) on 2017 Dec 24.82 UT.

The only emission clearly present is Hα, which displays a P-Cygni profile. Hβ, Hγ and Hδ are seen in absorption. A number of other absorption lines are also present, including Fe II multiplets 37, 38, 42, 48 and 49, Na I D and O I 7773 Å. This spectrum confirms TCP J00333837+4836022 is a classical nova eruption in the Local Group dwarf spheroidal galaxy NGC 147. Further follow-up of this object is encouraged.
