2023 Combe Hill formation
|
Reconstruction of the 2023 Combe Hill formation | ||
| 1. |
| Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed equilateral triangle of circle 1, pointing down. |
| 3. |
| Construct a circle, passing through the intersections of triangle 2 and the horizontal centerline, and tangent to circle 1 at the upper side. |
| 4. |
| Construct a circle concentric to circle 1, tangent to circle 3 at the lower side. |
| 5. |
| Construct the inscribed pentagon (regular 5-sided polygon) of circle 4, pointing up. |
| 6. |
| Copy circle 3 four times, to the other angular points of pentagon 5. |
| 7. |
| Draw the connecting line between the center of circle 4 and its lefthand intersection with the horizontal centerline. Divide this line into sixteen equal parts. Number the division nodes 1 - 15, from left to right. |
| 8. |
| Construct a circle concentric to circle 1, passing through node 7 nr. 10. |
| 9. |
| Copy circle 8 to the upper intersection of circle 1 and the vertical centerline. |
| 10. |
| Construct the inscribed pentagon of circle 1, pointing up. |
| 11. |
| Copy circle 8 to the lower lefthand angular point of pentagon 10. |
| 12. |
| Construct a circle concentric to circle 1, passing through node 7 nr. 9. |
| 13. |
| Copy circle 12 to the righthand angular point of pentagon 10. |
| 14. |
| Copy circle 8 to the lower intersection of circle 13 and the upper righthand circle 6. |
| 15. |
| Construct a circle concentric to circle 1, passing through node 7 nr. 12. |
| 16. |
| Copy circle 15 to the lefthand angular point of pentagon 10. |
| 17. |
| Copy circle 8 to the lower intersection of circle 16 and the upper lefthand circle 6. |
| 18. |
| Copy circle 15 to the lower righthand angular point of pentagon 10. |
| 19. |
| Copy circle 8 to the lower lefthand intersection of circle 18 and the lower righthand circle 6. |
| 20. |
| Construct a circle concentric to circle 1, passing through node 7 nr. 1. |
| 21. |
| Construct a circle concentric to circle 3, tangent to circle 20 at the lower side. |
| 22. |
| Copy circle 21 four times, to the centers of circles 6. |
| 23. |
| Construct seven circles concentric to circle 1, passing through nodes 7 nrs. 2, 3, 4, 5, 6, 7, and 8. |
| 24. |
| Construct a circle concentric to circle 1, passing through node 7 nr. 15. |
| 25. |
| Copy circle 24 five times, to the centers of circles 9, 11, 14, 17, and 19. |
| 26. |
| Draw five connecting lines, between the center of circle 1 and the centers of circles 25. |
| 27. |
| Construct five lines parallel to lines 26, the upper one at the lefthand side, the others rotationally corresponding, all tangent to circle 24 and circles 25, as shown. |
| 28. |
| Circles 3, 4, 6, 8, 9, 11, 12, 14, 17, 19, 20, 21, 22, and 23, and lines 26, and 27, are used for the final reconstruction. |
| 29. |
| Remove all parts not visible within the formation itself. |
| 30. |
| Colour all areas corresponding to standing... |
| 31. |
| ...or to flattened crop, and finish the reconstruction of the 2023 Combe Hill formation. |
| 32. |
| The final result, matched with two aerial images. |
