Pair of orange lights over western WisconsinWhile driving between St. Paul, Minnesota, and Eau Claire, Wisconsin, two of us observed two orange lights, larger and brighter than any stars, due east in the sky several miles away. The pair of lights, at the first observance, seemed to travel south in a leap-frog pattern, then disappeared.Several minutes later, they reappeared travelling much closer together, but disappeared within ten seconds. As we waited for their next appearance, I saw four to five planes (white blinking lights, assuming they were planes) travel to that area and stay in the area.One of the orange lights appeared again several degrees further south, then disappeared after only a few seconds, and I watched as the assumed planes headed in that direction. Over the course of the next hour, I waited and the orange lights did not return and the planes left the area.
