Configuration of the nucleus of the comet and jet with respect to the VIRTIS-M slit (horizontal red line) and its direction (red arrow). The VIRTIS-M data cubes are acquired with a temporal scan in which each line corresponds to a given time (white arrows). The orange thick line shows the Sun direction. The spacecraft is approximately in a terminator orbit with a phase angle of 90°, so that one side of the comet is illuminated by the Sun and the other side is in darkness.
