It was a partial eclipse rather than a total one, in which the Earth is cast into darkness. But it was the last partial solar eclipse visible from the continental United States until May 20, 2012.
Solar eclipses occur when the Earth, sun and moon line up in such a way that the moon casts a shadow over Earth.
Friday's eclipse will last from a few minutes to over an hour, depending on one's location. In much of the continental United States, people will see what looks like the moon taking a bite out of the sun, with the bite bigger over the South.
In Central America and the northern portion of South America, the sun was reduced to a narrow ring of fire.
Astronomers warned people not to stare directly at the sun without eye protection.
"It's neat to see the moon take a bite of the sun," said Tom Fleming, an astronomer at the Steward Observatory at the University of Arizona in Tucson. "Each eclipse is different because I remember who I was with and where I was when I was watching it."
The path of the eclipse will stretched about 8,800 miles through a corridor beginning near New Zealand and extending across the Americas.
In the United States, people living north of a line extending from southernmost California to central New Jersey saw no dimming of the sun at all.
The next solar eclipse will be Oct. 3, crossing the Iberian Peninsula to Africa.
