Watch live: Solar eclipse 2017

Dubai - The last time an eclipse crossed from the Pacific to the Atlantic Ocean was on June 8, 1918, when a total eclipse was visible from Washington to Florida.

On August 21, 2017, all of North America will be treated to an eclipse of the sun.

The total eclipse, when the Moon fully blocks light from the Sun, will be visible from a 113-kilometre path that carves through 14 US states. A partial eclipse begins on the northwest coast of the US shortly after 9am (1600 GMT). The total eclipse reaches the western coastline of Oregon at 10:16am Pacific time (1716 GMT), then forges a diagonal path, exiting over South Carolina in the afternoon.

While the darkest shadows will fall over this "path of totality", a partial eclipse extends far beyond it, and may be visible as far north as Alberta, Canada and as far south as Brazil, weather permitting. Even Britain and western France may catch an evening glimpse of a tiny sliver of the eclipse at sunset. "They'll see a very shallow, partial eclipse," said Royal Astronomy Society acting director Robert Massey.

The last time an eclipse crossed from the Pacific to the Atlantic Ocean was on June 8, 1918, when a total eclipse was visible from Washington to Florida.

Viewers around the world will be provided a wealth of images captured before, during, and after the eclipse by 11 spacecraft, at least three Nasa aircraft, more than 50 high-altitude balloons, and the astronauts aboard the International Space Station, each offering a unique vantage point for the celestial event, Nasa said on its website.
