DENVER -- If you saw something shooting across the Denver sky last night and were alarmed, don't be. It was a meteor.

People reported seeing the meteor around 8:40 p.m. Thursday, saying that was heading south and it had a bluish-green color to it.

The Denver Nature and Science Museum is interested in getting more information from people who saw the meteor.

If you think you did, you are asked to fill out a meteor information form at Cloudbait.com.

Scientists use those reports to estimate the orbit of the original meteoroid, and determine something about its parent body, and possibly find any possible meteorites that might be produced.

"If you can keep your wits about you, your observation could be scientifically valuable. First, make note of the time. Next, look around for references such as telephone poles, chimneys, trees, or peaks. Carefully note where you first saw the meteor, and where you last saw it. What is important to note for both of these points is the altitude, which is measured in degrees from the horizon (90 degrees is straight overhead), and the azimuth, which is measured in degrees clockwise from north. You also need to note your exact location, from a map or GPS receiver. Think about the colors you saw, whether pieces were breaking off, and whether there was a smoke trail or glowing air behind the meteor. If you heard any sounds, how long after you saw the meteor did they happen?" the Cloudbait Observatory said on its Web site.
