Triangular lights spinning slowly over a park and rising at a low angle.This happened around 9:20 pm on Firday, August 9th, 2002. I was biking in a new park with my cousin. It was dark, and no trees obscured the sky. Some stars where visible but very faintly. One plane was also observed, it appeared to be a passanger jet with clearly visible light beacons. When my cousin and I where close to a local school we both saw a peculiar three light triangular configuration in the sky, extremely low to the ground. I would say about 15 - 25 meters above the ground. The lights where clearly visible and definately not faint. They could not be mistaked for an airplane or stars. They where roundish white and a little yellowish. The lights gave an impression of a very large triangular object. The lights where about 30 meters from us when they slowly begun spinning and rising at the same time at a low angle. They gave an impression as if the object in the sky was very slow and heavy. The lights then accelerated as they where rising and completely disappeared.There was absolutely no sound heard throughout the event.
