I was out side smoking when I looked up and saw what I thought was a Large star. Then it started moving vast then very slow then not at all. I ran to show my husband who grabbed the video camera. The "object" was stationary for sometime then started to descend then ascend. Through the video camera, we zoomed in and it was changing colors and circling. It went from sea green to aqua to red. Then stayed white. Sometimes it would move across the sky fast them abruptly stop and other times it would just move slowly. Please try to tell me what this was. I have about 30 min of video.
