WASHINGTON (AFP) - A rare solar eclipse will sweep across parts of Africa, Europe and the United States on Sunday as the moon blocks the sun either fully or partially, depending on the location.
The round shape of the Earth explains why some viewers in west Africa will see a total eclipse, while others in the United States and Europe will only see the sun partly obscured.
Regardless, experts said people should not look directly at the sun during the unusual hybrid eclipse unless they use special welder's glass or view it indirectly with a pinhole filter. Regular sunglasses will not protect the eyes enough.
The greatest part of the eclipse will take place at 1237 GMT over the Atlantic Ocean, some 330km southwest of Liberia, according to a NASA website that tracks eclipses.
The west African nation of Gabon will get peak viewing of the total eclipse as it sweeps over a path nearly 60km wide. At its peak over land in central Gabon around 1350 GMT, the sun will be blocked out for about one minute.
"The eclipse will then continue across Africa through the Congos until it passes through northern Uganda and northern Kenya, ending in southern Ethiopia and Somalia," said the International Astronomical Union.
The eclipse will last about 10 seconds in northern Kenya.
Weather permitting, partial phases of the eclipse will be in southern Europe, including parts of Spain, Italy and Greece.
In the eastern United States, viewers may catch a partial eclipse close to sunrise at 6:30am in the Eastern Standard Time Zone (1130 GMT).
Experts say a safe way to view an eclipse is by making a pinhole camera - a 3mm hole in one piece of paper - then turning your back to the sun and using the pierced page to project the image of the sun on another sheet of paper.
