Many folks would like to see us back on the Moon and developing its resources.

Subject: [Faces from Earth] Watch Live - Total Solar Eclipse of July 11, 2010


A spectacular total solar eclipse will occur on July 11, 2010 over the ancient statues of Easter Island, where those lucky enough to have made it to the Pacific will witness the last total eclipse to occur until November 2012.

But some of the Eclipse Chasers/Groups are taking the extra effort to web-stream the Eclipse online for the rest of the world to watch!

I have compiled a list of live web-streams, please share it with your friends and other groups. It's an opportunity not to be missed.

An Exotic Solar Eclipse
February 3, 2010
by Fred Espenak and Jay Anderson

The third total eclipse of the Sun in three years is coming up on July 11th, when the long, thin finger of the Moon’s shadow will again draw its tip across Earth’s surface.

But unlike the spectacles in 2007 and 2008, which offered many possibilities for land-based viewing, the 6,800-mile (11,000-km) path of this eclipse is confined almost exclusively to the South Pacific Ocean. When greatest eclipse occurs, at 19:33:31 Universal Time (3:33:31 p.m. EDT), the duration on the central line is 5 minutes 20 seconds — but at a point hundreds of miles from any land.

Totality begins at sunrise almost 1,200 miles (2,000 km) northeast of New Zealand, at 18:15 UT. Five minutes later the Moon’s shadow makes the first of its very few appearances on terra firma. The island of Mangaia is a mountainous volcanic remnant in the Cook Islands just south of the eclipse path’s central line. The duration of totality here is 3 minutes 18 seconds, with the Sun 14° above the horizon.


Thanks for looking up with me.

NASA Solar Eclipse Bulletins
Annular and Total Solar Eclipses of 2010 (NASA/TP-2008-214171)

Two central eclipses of the Sun occur during 2010. The first is an annular solar eclipse on January 15 and is visible from a broad track across Africa, the Indian Ocean and south Asia. The second is a total solar eclipse on July 11 and is visible from a corridor that traverses the South Pacific.

Annular and Total Solar Eclipses of 2010 (NASA/TP-2008-214171) contains detailed predictions for both of these events and includes Besselian elements, geographic coordinates of the paths of annulatity and totality, physical ephemeris of the antumbra and umbra, topocentric limb profile corrections, local circumstances for hundreds of cities, maps of the eclipse paths, weather prospects, and lunar limb profile figures. Information on safe eclipse viewing and eclipse photography is also included.


The document Annular and Total Solar Eclipses of 2010
(NASA/TP-2008-214171) was written by Fred Espenak (NASA's Goddard Space Flight Center, Greenbelt, Maryland, USA) and Jay Anderson (Royal Astronomical Society of Canada, Winnipeg, Manitoba, CANADA).

Solar eclipse of July 11, 2010

A total solar eclipse will occur on July 11, 2010.[1]  A solar eclipse occurs when the Moon passes between Earth  and the Sun, thereby totally or partially obscuring Earth's view of the Sun. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun, blocking all direct sunlight, turning day into  darkness. Totality occurs in a narrow path across the surface of the Earth, while a partial solar eclipse will be visible over a region thousands of miles wide.

The eclipse will be visible over much of the southern Pacific Ocean, touching several small islands including Tuamotu in French Polynesia and Easter Island, as well as the southern tips of Argentina and Chile in South America.[2]
