A Total Lunar Eclipse will occur Wednesday night. This will be the last until 2010. It occurs only at Full Moon as the entire moon moves through the earth's shadow. You won't need any special viewing equipment, just look up. As of now I expect partly to mostly cloudy skies that night. Hopefully the clouds will hold off until after the eclipse. From start to finish the eclipse will last 3 hours and 26 minutes.
Here are the details:
The partial eclipse will begin at 7:43pm as the moon just begins to enter the earth's shadow. The total eclipse, where the moon will be completely covered by the earth's shadow, will last from 9:01pm to 9:51pm. During this time, the moon won't be completely obscured because of indirect light coming from the Earth's atmosphere. This is also when the moon will appear to change colors from light gray to orange or deep red. ...pretty cool stuff if you've never seen it before. The shade depends on the amont of dust and clouds in the atmosphere.
On Wednesday evening the Saint Louis Science Center's Planetarium will host an educational program beginning at 7:00 pm, followed by telescope viewing of the eclipse with members of the St. Louis Astronomical Society. The entire evening is free and open to the public.
