Light ball flew slowly over forest, stopped and landed thereIt was dark and clear sky, no Moon visible, wintertime and temperature was below zero.I and my uncle were standing in the yard of my grandparent's farm-house in rural country and other uncle made some work farther away.Then I suddenly noticed a car-sized, bright, white, clear-cut and slow-moving round Light Ball what flew just about 5 meters over the top of trees. I attracted attention to my nearest uncle saying look at that. The object was totally silent and its distance from us was about 400-500 meters. It situated about 100 meters from the edge of forest and went horizontally about 300 meters to the west according the edge of forest.While we were watching it, the object suddenly stopped and stayed a moment in place. Then it landed very slowly and slightly diagonally to the forest and disappeared finally there.. Afterwards, my uncles didn't talk about it at all.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
