This Sunday brings the first annular solar eclipse visible in the western United States in almost 18 years. Mike Wall reports for Space.com:
Skywatchers in East Asia and the western United States should circle Sunday (May 20) on their calendars. That’s when a solar eclipse will block out most of the sun, leaving a spectacular “ring of fire” shining in the sky for observers located along the eclipse’s path.
The event is what’s known as an annular solar eclipse — from the Latin “annulus,” meaning “little ring” — and its full glory should be visible from much of Asia, the Pacific region and some of western North America, weather permitting. At its peak, the eclipse will block about 94 percent of the sun’s light.
Other parts of the United States and Canada will still see a partial solar eclipse, without being treated to the ring of fire effect, though the East Coast will miss the event since the sun will have set before it begins.
