On Aug. 28, skywatchers across much of North America can watch as the Moon crosses into the Earth's shadow and will undergo its second total eclipse in 2007.
West Coast viewers will get the best show.
Lunar eclipses occur when Earth gets between the sun and the moon, casting a shadow. The view is different from each location on the planet. Along the West Coast of Canada and the United States and in Alaska, the entire eclipse will be visible from start to finish before moonset in the early morning hours of that Tuesday. Hawaiians will see totality – when the moon is completely in Earth's shadow – high in their sky around midnight.
In eastern Asia and Australia, the event will occur on the same date but in the evening, since for this part of the world it will coincide with moonrise.
