Reconstruction of the
1997 Alton Barnes formation |
|
| 1. |
 |
Draw a circle. Draw the horizontal and vertical centerlines. |
|
| 2. |
 |
Construct an equilateral triangle with the top at the upper endpoint of the vertical centerline.
|
|
| 3. |
 |
Construct three more equilateral triangles, at each of the other endpoints. |
|
| 4. |
 |
Construct a circle touching two sides of the first triangle and touching the outer circle, all at the inner sides. |
|
| 5. |
 |
Construct two more similar circles touching the other pairs of the sides of the triangle. |
|
| 6. |
 |
Repeat steps 4 and 5 for the other three triangles. |
|
| 7. |
 |
Leaving out the outer circle, the centerlines and the four triangles finishes the reconstruction of the 1997 Alton Barnes formation. (This reconstruction assumes an exactly symmetrical formation). |
|
|
| 8. |
 |
Would the Circlemakers have finished this formation in the same fashion as the Woodborough Hill (3) 2000 formation, then it should perhaps have looked like this. Through the intersections of the existing circles, draw concentric circles around the main center. |
|
| 9. |
 |
Make black every other "triangle" (now all three sides are curved) in a checkerboard-like fashion. |
