Although not specifically referring to the phenomenon what it is, but with reference to the pictures included, as well as other photographs that later appeared on the internet, the observer is convinced that it is the UFO phenomenon what is known as "Crop Circle", and generally a lot appears in the UK.
Crop circles is a regular pattern that forms mysteriously in the area of crop fields, often overnight. The phenomenon was first discovered in Britain late 1970, with a simple circle patterns. In those days thereafter, this pattern tends to get complicated and not limited to one circle.
A community of UFO watchers who call themselves BetaUFO Indonesia, then declared that the crop circles found in Yogyakarta, is not manmade. This conclusion was drawn after they sent a team to the location on Monday (24 January, 2011).
According to their research, the lying paddy at the site was not damaged. This is one indication that the crop circles were not made by man.
The second mysterious crop circles then were found again in Bantul (near Sleman) Yogyakarta on Tuesday, 25 January, 2011.
Is this natural or UFO phenomenon ?
