3 white orbs. 2 in front 1 behind.I saw these whilst lying down in bed with my daughter's. It was sunset, the sky was mostly dark and the first 2 came from the back side of my house along side each other-about north/east. They were not moving too fast but were traveling at a steady pace. I followed them by running out to my living room when they went past my line of view. They continued on their path until one seemed like it just slowly winked out eventually followed by the other.I went to go lay back down, my oldest was tired, when I saw the third. This one came from the same direction but at a faster pace. I didn't follow this one because my daughter needed me, but I wanted to. I am posting this now because I can not understand what this is, and I have been trying to find out more about it.I have 2 videos of this incident, the first one is pretty shaky and my dog barked pretty loudly, but the second one is steady. I may upload them to YouTube.
