Large fireball lights and formation seen over Beijing, China that lasted for at least three hours.Eleven American students, an American teacher, a Chinese guide, and myself (one of the American students traveling in Beijing, China) witnessed strange colorful lights in the sky during a bus ride around 10:00 PM on July 2, 2008, as well as from our hotel rooms up until 1:00 AM when we went to bed. I looked out the bus window and saw two large flare shaped lights hovering over the city (one green and one blue). I asked the Chinese guide what they were, and neither she nor anyone else could explain them. They were not fireworks. A few seconds later, a red one appeared in a different location for a brief moment when it quickly vanished as several white lights flashed around it. We arrived at our hotel and my roommate and I looked out our 8th story window to see a pentagonal formation of five lights as well as two green lights with long flickering tails slowly moving over the horizon towards the formation. The formation spanned a distance several miles wide and several miles high in the night sky. The light on the far left of the formation was rapidly changing color from blue to green to purple to red to yellow and so on. The other four lights were yellow or white in color and were slowly moving along the perimeter of the pentagon. My roommate and I watched the lights for nearly two hours. A couple of times during the event a red light shot out from the colorful light and eventually returned to the colorful light.As we watched the green lights rise toward the formation we noticed that once they reached a certain height in the sky, they lost their shimmering tails and green color and joined the formation of yellow and white lights. The most shocking moment came when three of the green lights with tails were traveling toward the formation. At the same time as if connected by an unseen force, they all swayed quickly to the left, and back to the right. We continued to watch the lights and even tried to take some photos and video, but lights of the buildings in Beijing were too bright to get a ! clear sh ot, and the images and videos barely show the lights. We thought of every possible explanation for the source of the lights, but nothing could explain their unique movements.((NUFORC Note: Source of report indicates that the date of the incident is approximate.
