I went to let my dog inside. Something cought my eye and I looked up an saw four hovering square shaped lights about tree-height above me . I was unable to get a clear view of the object due to cloud cover. However I could clearly see the lights through the cloud cover . At first I thought it could be a helicopter . But I heard no sound and the lights were in a square shape . I watched the object for about ten minutes and then they just vanished .
