Reconstruction of the
2020 Berwick Bassett Clump formation |
|
1. |
| Draw a circle. Draw the horizontal and vertical centerlines.
|
|
2. |
| Construct the inscribed regular 11-sided polygon of circle 1, pointing up.
|
|
3. |
| Construct the inscribed circle of polygon 2.
|
|
4. |
| Draw two connecting lines, from the lefthand intersection of circle 3 and the horizontal centerline, to its upper and lower intersections with the vertical centerline.
|
|
5. |
| Construct a circle tangent to circle 3 at the righthand side, and tangent to both lines 4.
|
|
6. |
| Draw a ray of polygon 2, from its center to the lefthand angular point just above the horizontal centerline.
|
|
7. |
| Draw a ray of polygon 2, from its center to the righthand angular point just above the horizontal centerline, and extend this line upto the opposite side of circle 1.
|
|
8. |
| Construct a circle inside, and tangent to circle 5 at the lefthand side, and tangent to lines 6 and 7.
|
|
9. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the righthand intersections of circles 5 and 8 with the horizontal centerline.
|
|
10. |
| Construct a "two-points" circle between the centers of circles 5 and 9.
|
|
11. |
| Construct a circle concentric to circle 10, tangent to the vertical centerline.
|
|
12. |
| Construct a "two-points" circle between the righthand intersections of circles 10 and 11 with the horizontal centerline.
|
|
13. |
| Construct a circle concentric to circle 10, passing through the center of circle 12.
|
|
14. |
| Circles 1, 3, 5, 8, 9, 10, 11, and 13, are used for the final reconstruction.
|
|
15. |
| Remove all parts not visible within the formation itself.
|
|
16. |
| Colour all areas corresponding to standing...
|
|
17. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Berwick Bassett Clump formation.
|
|
18. |
| The final result, matched with the aerial image.
