http://eclipse.gsfc.nasa.gov/lunar.html The last total lunar eclipse of the year is Saturday. And there won't be another one for three years.
Viewers in the western half of the United States will have the best views Saturday well before dawn. The farther west the better.
This is the second total lunar eclipse this year, when the entire moon is in Earth's darkest shadow and will appear red. The first was in June. That's it now until 2014.
