Several red orange lights in arch formation.Several round red orange circles in an arch. Slowly separated and dimmed and brightened. Some at very high altitude. Lights disappeared as we got closer. As we followed the last light it faded out and wevcould see the oval silhouette as it moved away slowly and then took off at a high rate of speed. One of the other lights went straight up when we drove under and then took off very quickly in the other direction. Asked locals at a nearby store on the west side about the lights. They told us friends frontage east side had also seen lights earlier in the night.
