Every night when the sky is clear of clouds and dark at night, in between 8:00pm -9:00pm there are 4-5 squares that hover in the sky above my house.The squares appear to have one red light on the top corners and one white light on the bottom corners. These squares just hover. Over time these things will go up and down slowly and they will move left and right at different heights.Sometimes they will move southeast of my house and appear to go up and down hovering over a power station near my house. After doing that for a while they will return to the sky over and around my house.When you look at these things with a gun spotting scope they appear to be balls of lightning.I have watched these things for the last six months.I need someone to come to my house and tell me what these are.
