NEW YORK (AP) — A total lunar eclipse will flush the moon red Thursday night into Friday morning across the Western Hemisphere.

The best views will be from North America and South America. Parts of Africa and Europe may catch a glimpse.

Lunar eclipses happen when the moon, Earth and sun align just so. The Earth casts a shadow that can partially or totally blot out the moon.

During a partial lunar eclipse, Earth’s shadow appears to take a bite of the moon. The full moon is covered during a total eclipse and blushes coppery red because of stray bits of sunlight filtering through Earth’s atmosphere.

The so-called blood moon will be visible for about an hour starting at 2:26 a.m. Eastern on Friday morning. Peak viewing will be close to 3 a.m. Eastern.

To see it, venture outside and look up — no need for eclipse glasses or any special equipment.

“As long as the sky is clear, you should be able to see it,” said Shannon Schmoll, director of Abrams Planetarium at Michigan State University.
