This Circle appeared at Avebury Manor July 15, 2008 showing the precise orbital locations
for all nine planets of our solar system on December 23, 2012,
(2 days after the Mayan Long Count calendar ends) plus an accurate elliptical orbit for Pluto
About a week later, on July 23rd 2008 the diameter of the "sun" in the formation was enlarged to encompass
the orbits of both Mercury and Venus. and a second circle appeared next to it as seen here.
This is an intriguing formation and I would like to hear what you all make of it.
