The design, the first in the UK this season and this decade is a big shout-out to the NHS and Key Workers, according to some who seem to know a lot about it. It is a great design with some elements seen in previous circles. The Clandestine Esoteric Mysterious Universe Facebook page seems to carry the lead on this design. The location has been withheld to prevent a rush to view it.
Also on the Clandestine Esoteric Mysterious Universe Facebook page is a teaser to the new Cley Hill formation. Below is a little drone footage of the above formation. There is also some further information over at Crop Circle Connector.
The Croppie also has a great page on this circle.
