We obtained a spectrum of the transient PNV J01044358+0203419 in the IC 1613 field (see CBAT TOCP) with the SPRAT spectrograph on the Liverpool Telescope (Steele et al. 2004) on 2015 September 17.1 UT.

The spectrum shows strong Balmer emission lines, along with Fe II (4924, 5018 and 5169 Å), Na I and O I (7773 Å) emission features. Several of these emission lines show evidence of P-Cygni absorption profiles. The spectrum indicates that the transient is a nova and a member of the Fe II spectroscopic class.

The transient appears coincident with a source at 01:04:43.56 +02:03:42.0 (J2000) in the catalogue of stars in the IC 1613 field published by Udalski et al. (2001), who report it to be at magnitude V = 22.06 and I = 21.53.

We conclude that PNV J01044358+0203419 is an extragalactic Fe II nova, and likely resides in IC 1613.
