Reconstruction of the 2016 Ranscomb Bottom formation | ||

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

2. |
Construct the inscribed pentagon (regular 5-sided polygon) of circle 1, pointing up. | |

3. |
Draw the five diagonals of pentagon 2. Number these diagonals clockwise 1 - 5, starting at the horizontal one. | |

4. |
Construct the inscribed pentagon of circle 1, pointing down. Number the sides clockwise 1 - 5, starting at the upper one. | |

5. |
Construct the circumscribed pentagon of circle 1, the lower side horizontally. | |

6. |
Extend the sides of pentagon 2 each in both directions upto pentagon 5. | |

7. |
Construct the inscribed decagon (regular 10-sided polygon) of circle 1, by connecting the successive angular points of pentagons 2 and 5. | |

8. |
Draw the five diagonals of the pentagon enclosed by diagonals 3. | |

9. |
Draw the five diagonals of pentagon 4. | |

10. |
Draw the connecting line between the intersection of diagonal 3 nr. 5 and side 4 nr. 1 and the intersection of diagonal 3 nr. 1 and side 4 nr. 5. Repeat this four times for the other corresponding intersections of diagonals 3 and sides 4, as shown. | |

11. |
Draw the two diagonals of the lower righthand parallelogram enclosed by pentagon 5 and lines 6. | |

12. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the intersection of the upper lefthand and upper righthand diagonals 9 and the intersection of diagonal 3 nr. 1 and the vertical centerline. | |

13. |
Copy circle 12 to the intersection of diagonals 11. | |

14. |
Copy circle 12 four more times to the other positions with respect to pentagon 5 corresponding to circle 13, as shown. | |

15. |
Lines 3, 4, 5, 6, 7, 8, 9, and 10, and circles 13 and 14, are used for the final reconstruction. | |

16. |
Remove all parts not visible within the formation itself. | |

17. |
Colour all areas corresponding to standing... | |

18. |
...or to flattened crop, and finish the reconstruction of the 2016 Ranscomb Bottom formation. | |

19. |
The final result, matched with two aerial images. |
