Siloam Springs, Ark (November 5, 2003) - (Little Rock-AP) -- A total lunar eclipse will be visible across most of Arkansas on Saturday evening, provided that cloudy conditions forecast for the day clear up in time. The partial eclipse starts about 5:32 p.m. The total eclipse phase begins at 7:06 p.m. and will last just 25 minutes. It will be the only eclipse -- lunar or solar -- visible this year in Arkansas. A lunar eclipse occurs when the moon passes in the shadow of Earth, emitting a red glow as sunlight is refracted by Earth's atmosphere. No telescope is required to see the eclipse. But, mostly cloudy conditions are forecast across much of the state. Some clearing could come later in the night.
