Reconstruction of the
2007 Southend formation
1. Draw a circle. Draw and extend the horizontal and vertical centerlines.
2. Copy circle 1 to its lower intersection with the vertical centerline.
3. Copy circle 1 to the lower intersection of circle 2 and the vertical centerline. Move this circle (copy and delete original) to its own lower intersection with the vertical centerline
4. Repeat step 3 eight times, first with respect to circle 3, then with respect to each newly copied circle, as shown.
5. Repeat step 3 once again, with respect to the last (lowest) circle 4, to yield eleven circles in total on a vertical row, head to tail, as shown.
6. Construct a "two-points" circle, defined by the end-points of a centerline, with the points at the centers of circles 1 and 5.
7. Construct a two-points circle, with the points at the lower intersections of circles 2 and 5 with the vertical centerline.
8. Construct a two-points circle, with one point at the lower intersection of circle 3 and the vertical centerline, and the other point at the center of circle 5.
9. Steps 9 through 15 are a repetition of steps 7 and 8, each with respect to the next circle 4 for the upper point, and alternately the lower intersection and the center of circle 5 for the lower point.

First circle 4, lower intersection of circle 5.
10. Next circle 4, center of circle 5.
11. Next circle 4, lower intersection of circle 5.
12. Next circle 4, center of circle 5.
13. Next circle 4, lower intersection of circle 5.
14. Next circle 4, center of circle 5.
15. Next circle 4, lower intersection of circle 5.
16. Construct a circle concentric to circle 1, passing through the center of circle 3.
17. Copy circles 5 through 15, while mirroring with respect to the horizontal centerline.
18. Circles 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 and 17 are used for the final reconstruction.
19. Remove all parts not present in the formation itself.
20. Colour all areas with standing...
21. ...or with flattened crop; this will finish the reconstruction of the 2007 Southend formation.
22. The final result, matched with the aerial image.
