The six lines in this crop circle show the relative trajectories of the six comets. They are divided into three groups of two parallel lines each. The hexagonal centre represents the impact area for all six. Looking at the diagram, the two parallel lines which are also horizontal are the trajectories for Comets C and D. The two trajectories slanting down from left to right are for A and B. The two slanting downward from right to left are for E and F. These identifications are  are based on a number of prior crop circles.
