While sitting in a large-windowed kitchen overlooking open fields on a bright clear morning with high visibility, we, as a family of three, saw a spherical metallic-looking object of darkish aluminum color, the size of a sedan-car tire, flying over the front field, some 30-40-meters from us.

The object was flying with a slow steady pace, 1-meter above the field.  When it reached the end of the field, some 170-meters down, and met a thick line of trees and shrubs, it stopped, made a 90-degree turn and flying another 40-meters it reached the artesian well covered with a 2-meter-high concrete protective structure.  It stopped before the structure, rose up, went over the structure and hovered motionless over it.  
After hovering motionless for some 20-30 seconds, it instantaneously rose and flying fast in some 60-degree upwards it disappeared from sight within some 5-10 seconds.
Witness indicates that the date of the sighting is approximate.  PD
