It was a little after 7:00 pm, I was getting the kids into bed when my mother noticed something out the window. She had us all come to the window to look. We saw 7 objects hovering in the air. We grabbed her phone to take a picture, but we couldn't get a good shot.I got the camera and went outside with my oldest child. Everyone else stayed in the house looking out the open window. By the time we got outside there were only four left in the sky that we could see. The three lighter ones formed a large triangle. They looked like they were moving but remained in the same place in the sky the entire time.The largest one was very bright and appeared to be moving fast, toward the triangle of lighter ones.It continued like this for approximately 20 minutes, until the lighter ones just disappeared and the brighter one went behind the tree line and we could no longer see it.We took several pictures and a video of the object's. On one of the pictures of the larger one we were able to zoom in on the computer. What we saw was very strange. The large one was very angular with sharp edges.We are very curious to know what these were. I am emailing some of the pictures that we took.
