Olivier Morell - Roy  Norwegian cameraman and myself spent the night around Silbury Hill. I have never experienced the amount of lights in the sky at any one time. At one stage we just didn't know which one to concentrate on ( I'm almost certain that I have caught one of the crop circle makers  again on still camera). We discovered this formation at day break from Silbury Hill at approx 04.30 am. A wonderful Ying Yang formation, crisp with all the regular features.
