We saw a cluster of ca 15 slightly orangish lights moving silently & independently SE just above the horizonMy wife and I stopped at a restaurant on the edge of town after seeing a movie. We left the restaurant about 23:00. It was a clear night. Coming out of the restaurant, to the SE we saw about 10 to 15 slightly orangish lights just above the horizon. For a second we thought it was a star formation, but they were moving and there were too many and they were too low and too close to the ground. And they had a slightly orangish color. Then for a second I thought fireworks. But there was no noise and some of them stood still in the sky and others moved. They were moving on their own individually. They were not in any tight unified formation, but rather in a cluster, but moving independently one from the other. Some would stand still for a while. Others would move, some up, some gradually disappeared off to the right. Those to the left stayed longer, but eventually they too moved away and disappeared from sight.The whole thing lasted about 10-20 minutes. They were not aircraft, not helicopters, not fireworks. They behaved differently than all of these. They behaved differently than anything else we had ever seen.There are German Army barracks in that area so we stopped by there the next day to see if they had night operations that night. They said no, it had nothing to do with them.((NUFORC Note: The source of this report telephoned our Center on Sunday morning, June 08th, and left a detailed oral report about the sighting. We returned the call, and are satisfied that both witnesses to the event are sober-minded individuals, and that they probably are quite credible sources of information about the sighting. PD))
