Crop formations have appeared in a field on the outskirts of Brighton.
The linked circles are clearly visible on the right-hand side of Ditchling Road when travelling into the city.
Commuters stopped by the side of the road to look at them after they appeared last week.
And they have now attracted the attention of experts in the phenomena.
Paranormal researcher James Webster said he planned to travel from his home in Battle to examine them.
He said: "It is difficult to say whether they are genuine or not until I have seen them. There are hoaxers which have explained some circles but by no means all of them. It is certainly rare for formations to appear in Sussex."
