2011's Last Solar Eclipse Shows Off for Southern Hemisphere

Photographer and skywatcher Bernt Olsen snapped this view of the partial solar eclipse of June 1-2, 2011 just during the "midnight sun" in Tromso, Norway. The partial solar eclipse was dubbed a "midnight" eclipse as its viewing path crossed the International Date Line across far northern latitudes.

The last solar eclipse of 2011 will put on a show for some in the Southern Hemisphere on Friday (Nov. 25), but Americans shouldn't bother to look up from their Thanksgiving leftovers.

According to NASA, viewers in South Africa, Antarctica, Tasmania and most of New Zealand will see the partial eclipse at 06:20:17 Universal time (1:20 a.m. Eastern time). With a magnitude of 0.905, this is the largest partial eclipse of the year, hiding much of the sun.

Solar eclipses occur during new moons, when the moon passes between the sun and the Earth. If the moon casts a shadow on the Earth during this phase, the result is an eclipse. From Earth, the result is that the moon seems to obscure the sun. (In contrast, lunar eclipses happen when a full moon passes into Earth's shadow, obscuring our view of the moon. The next lunar eclipse will occur on Dec. 10, 2011.)

The number of solar eclipses varies each year between two and five. In 2011, there were four solar eclipses . In 2012, astronomers predict just two. The next solar eclipse will be on May 20, 2012, and more Northern Hemisphere denizens will get a shot at seeing it: The eclipse will be viewable from eastern Asia to parts of the western United States.
