CAMPING -- The "Blood Moon" will treat sky watchers who can stay up past 11 p.m. tonight. The weather forecast indicates the viewing of the lunar eclipse will be good.
And if you have a warm sleeping bad, it might be a good night to doze off under the stars.
- The bloody red color the moon takes on during an eclipse is caused by refraction of sunlight by the Earth's atmosphere.
Tonight will be the first in the rare sequence of four total lunar eclipses expected in the next two years.
See details of the eclipses, and their role in Christian lore, in this story by USA Today.
