Reconstruction of the
Buchendorf (Germany) 28-07-2021 formation

1. Draw a circle. Draw the horizontal and vertical centerlines.

2. Construct the inscribed nonagon (regular nine-sided polygon) of circle 1, pointing to the right.

3. Construct the inscribed circle of nonagon 2.

4. Construct two inscribed equilateral triangles of circle 3, one pointing to the left, one to the right.

5. Construct a circle concentric to circle 1, passing through the intersections of triangles 4.

6. Construct the inscribed nonagon of circle 5, pointing to the right.

7. Construct the inscribed circle of nonagon 6.

8. Construct a circle, tangent to the leftmost two sides of triangles 4, and tangent to circle 7 at the outer side.

9. Copy circle 8 to the center of circle 1.

10. Construct a circle centered at the rightmost angular point of triangles 4, tangent to circle 1 at the righthand side.

11. Copy circle 10 five times, to the other angular points of triangles 4.

12. Construct the inscribed equilateral triangle of circle 7, pointing to the right.

13. Copy circle 10 three times, to the angular points of triangle 12.

14. Circles 1, 3, 5, 7, 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 Buchendorf (Germany) formation of 28-07-2021.
