'After many times crop circles appeared in Europe, and only viewed via internet, for the first time I saw myself CC in my city, here, at Yogyakarta, Indonesia. Exactly at Rejosari, Jogotirto Berbah, Sleman about 7-10kms south of Prambanan temple.
`This CC probably appeared on Saturday night since farmers saw the unique shape of their rice field early in the Sunday morning January 23, 2011. Maybe this location was chosen because it near the hill so people could see this CC by climbing the hill, and uniquely it's under tower of electricity cable line.

This phenomenon was first known by Yudi, 20. 'Around five o'clock this morning, I left for work. While passing this field, I saw the rice-paddy, but collapsed to form a neat pattern,' said Yudi.
