We compare the N V λ1240 line in J1608 with predictions from the BPASS models (Stanway et al. 2016) for a 1 Myr and 3 Myr instantaneous burst with a 150 M☉ upper mass limit. The height and depth of the N V line suggest an age close to 1 Myr. Lyα absorption affects the blue side of the observed N V profile.
