Driving saw light change and move on crazy ways got video

I was driving, at first I noticed a big circle shape of a couple of different colors of light. It was really clear and I cud see it well. The lights would change color and it was like darting around. I watched for a min. Then realized i needed to get a pic at least. While I was fumbling g with my phone, trying to keep my eyes on it and turn camera on it almost instantaneously shot west about 20 miles I think from above the city of ione to above Rancho Seco nuclear plant, and as it did the light blinked out the came back on but dull and thats when I got the video and recorded til it disappeared. It's taken me awhile to report because I can't believe what I saw was real and I didn't want to waste an investigators time, but what I saw wasn't normal. I wish the video was better and that I had video of what it was like before it went dull, it was huge and bright and clear.
