Rectangular moving object's shadow on the cloud cover under the bright moonTwo days after full moon, the moon was still at its best size, and the moon is right above my head at that time, there was a clouds covering under the moon except for a hole through which I witnessed the moon, I was thinking about nature and the beauty of the scene, suddenly, I saw a rectangular object's shadow on the cloud cover between the moon and the earth, so the object was moving inbetween the moon and the cloud cover at a tremendous speed, the moving object's shadow lasted for few seconds.
