Cannot tell from ground but seems to consist of several thin elliptical or curricular rings with wide separation between them and then something going on within all that. Only viewpoint I could find was on the north side of the A4 from on top of the tumulus. Formation has a telegraph pole within its rings. Confirmed sighting  23rd May 2003. Whether this crop is coming back up or was never laid to the ground will have to wait for someone to go in.
