One member of the WCCSG team spent the night of the 20th June on a Solstice nightwatch near Silbury Hill.
While he, with one group camped out there, another separate group were on watch across the road at West Kennett Longbarrow.
As the hours of darkness passed, many strange lights were observed in the sky above the longbarrow and in the surrounding area. The group ruled out any logical explanation for these lights - satelites, aircraft etc. Their reports tell us that the balls of lights were numerous, and at times, they moved toward one another before separating again.
As the sun began to rise on the morning of the 21st June, the shadow of what could be a crop circle was visable through binoculars from Silbury Hill at 4.13am. At around 4.35am, Olivier from our group and his companion Andrew Pyrka were the first to set foot in the beautiful Yin Yang formation.
There had been no reports from the watching groups of any obvious human activity in the fields during the night.
Below is a diagram of a formation resembling a 3D vortex that appeared in 2006 at Winmill Hill near Avebury Trusloe. See the similarity between this and the pattern from this Yin Yang formation.
