The annular eclipse, in which the moon passes in front of the sun leaving only a golden ring around its edges, was visible in Asia early Monday. It then moved across the Pacific — and the international dateline — and was seen in parts of the western United States Sunday afternoon.
In Japan, "eclipse tours" were arranged at schools and parks, on pleasure boats and even private airplanes. Similar events were held in China and Taiwan as well, with skywatchers warned to protect their eyes.
In the U.S., viewing parties were held at observatories in Reno, Nev., and Oakland, Calif., and elsewhere. In some areas, special camera filters for taking photographs have been sold out for weeks in anticipation of the big event.
People from Colorado, Oklahoma and as far away as Canada traveled to Albuquerque to enjoy one of the best vantage points at a park on the edge of the city.
Members of the crowd smiled and cheered and children yelled with excitement as the moon crossed the sun and the blazing halo of light began to form. Some watched the eclipse by placing their viewing glasses on the front of their smartphones.
Eventually, the moon centered and covered about 96 percent of the sun.
"That's got to be the prettiest thing I've ever seen," said Brent Veltri of Salida, Colo.
The eclipse was broadcast live on TV in Tokyo, where such an eclipse hasn't been visible since 1839. Japanese TV crews watched from the top of Mount Fuji and even staked out a zoo south of Tokyo to capture the reaction of the chimpanzees — who didn't seem to notice.
A light rain fell on Tokyo as the eclipse began, but the clouds thinned as it reached its peak, providing near perfect conditions.
"It was a very mysterious sight," said Kaori Sasaki, who joined a crowd in downtown Tokyo to watch event. "I've never seen anything like it."
At the Taipei Astronomical Museum in Taiwan, the spectacle emerged from dark clouds for only about 30 seconds. But the view was nearly perfect against Manila's orange skies.
"It's amazing. We do this for the awe (and) it has not disappointed. I am awed, literally floored," said astronomical hobbyist Garry Andreassen, whose long camera lenses were lined up with those of about 10 other gazers in a downtown Manila park.
Hong Kong skywatchers weren't so lucky.
Several hundred people gathered along the Kowloon waterfront on Hong Kong's famed Victoria Harbor, most of them students or commuters on their way to work. The eclipse was already underway as the sun began to rise, but heavy clouds obstructed the view.
The eclipse followed a narrow 8,500-mile path for 3 1/2 hours. The ring phenomenon lasted about five minutes, depending on location. People outside the narrow band for prime viewing saw a partial eclipse.
"Ring of Fire" eclipses are not as dramatic as a total eclipse, when the disc of the sun is entirely blocked by the moon. The moon is too far from Earth and appears too small in the sky to blot out the sun completely.
Doctors and education officials have warned of eye injuries from improper viewing. Before the event started, Japan's Education Minister Hirofumi Hirano demonstrated how to use eclipse glasses in a televised news conference.
Police also cautioned against traffic accidents — warning drivers to keep their eyes on the road.
