The details for the circle discovered below the White Horse Pewsey are as follows. I was out testing my aircraft engine that was fixed last night and was found to be a little lacking in power when flown home. I got up very early this morning and flew as far as Clench Common airfield and back to give the engine a proper warm. The engine seemed fine today. Turning back from clench over Pewsey I saw a very large crop circle beneath the White Horse chalk marking. I flew over and took some photos and it seemed a complicated and very large design. Then I flew back through my regular route of  the Barge Inn Honeystreet and saw another new circle next to the barge. There was also an apparent wind damage "circle" which looked very pronounced in the field next to the Barge Inn circle. I think it would be worth people checking that circle out. 

Hope the info and photos are of use to you.
