Intriguing features regarding possible symbolic value. Here are my intuitive associations:

Is the outside circle an "orbital path" with 2 suns on it, one being our sun and the other being its brown dwarf twin star. Are those inner dark spots (coiled like "serpent in the sky") the comet cluster which that dark twin sun puts on a collision course with 3D Earth every 3600 years (due now)? Do those 4 large circles represent the new 4D Earth coming?

Any guesses what that smaller black spot represents on the orbital circle?

Article Comments: "There seem to be other changes coming to our Solar System represented here. In the Crop Glyph, the Planet Pluto is gone. Moving in from the outer planets, we can see Neptune, Uranus, Saturn and Jupiter exactly as depicted in our "normal" Solar System arrangement as it is at present. But, after that, there is a significant difference. In the position of Mars, there seems to be four bodies. A single large body would be depicted differently, so I think it is four small ones shown rotating around an axis. Does this mean that Mars will be broken in pieces? Perhaps. Perhaps not. But next, we have two bodies in the "designated" position of the Earth."

Now, does this mean that the Earth will acquire a twin; another planet, or does it mean a dimensional split of our present planet? Or does it indicate to us that our planet will change its position?

The Cs stated:

Q: (J) Is there any criteria you can give us to measure
against, is there anything in particular to look for? Or
would it pop out as something strange that doesn't
make sense in a crop circle if you examine it? Or is
there actual...
A: One thing to look for would be growth disruptions to
the area. Real circles do not disrupt the creative
principle.
Q: (J) Now would this lack of disruption of the creative
principle apply to crop circles created by STS, STO, or
both?
A: STO.

Judging from these pictures, the affected plant medium looks flattened and dead, not gently swirled. It appears that the "creative principle" has been quite well "disrupted" in this circle.
