Looks like the sun with 12 rays. Two separate patterns within. Not quite symmetrical but very subtle patterns. It could be some kind of clock. Maybe it's pointing to a time or date. You would have to be familiar with reading a clock/calender like this to understand it though. The Mazzaroth is used by God for his timeline, the astrological clock is used by some cultures. There are endless calenders used by different cultures.

Doesnt appear to resemble images from Sumerian tablets although you might expect it to. Perhaps Angels are communicating with each other.

Someone once told me they dreamed of an angel making a tornado. It destroyed buildings but did not harm any person. They must communicate with others when they are working.

I've noticed both in the Solar and lunar calenders 22 and 23 are significant dates for equinoxes, passovers etc.

I found this information on a website which makes me think it could be angelic or other beings. I dont think the messages are meant for people as they are not situated in a way that people could easily see them even if they understood how to read them.

Winds

Probably the most scientific theory says that crop circles are created by small currents of swirling winds called vortices (similar to "dust devils"). The spinning columns force a burst of air down to the ground, which flattens the crops. Vortices are common in hilly areas such as parts of southern England.

Dr. Terence Meaden of the Tornado and Storm Research Organization (TORRO) in Wiltshire, England, says the vortices that create crop circles are charged with energy (his idea is called the Plasma Vortex Theory). When dust particles get caught up in the spinning, charged air, they can appear to glow, which may explain the UFO-like glowing lights many witnesses have seen near crop circles.

These images are so clear. It's truly amazing.
