We were travelling east on the M4 from Swansea coming home on Between J18 and J17 on the South side of the motorway. The circle was approximately 100 yards from the edge of the field and was clearly visible travelling east on a slight rise in the field, but it may not have been visible travelling west. It was a single circle approximately 60 feet diameter and I am 95% sure it was in wheat. The field was being harvested so it would have been gone that day. A 1/2 mile further down the motorway we passed a "Wiltshire" border sign . my guess is that we were around Burton.
