Composite LOOK images of comet C/2018 F4 in the ﹩{r}^{{\prime} }﹩ band marked with observing dates in UTC. A scale bar of 20″ in length and position angles of the antisolar direction and negative heliocentric velocity projected onto the sky plane are marked. The images all have J2000 equatorial north pointing upwards and east pointing to the left. The comet had split into two major components by the earliest LOOK observation; we refer to the upper and lower ones as Components A and B (designated C/2018 F4-A and C/2018 F4-B by the Minor Planet Center), respectively.
