The following is a guide to phenomena that occur before, during, and after annular and total eclipses of the Sun. If you’ve never experienced one or both these types of solar eclipses, this page will tell you what to expect, and when.| Solar Eclipse Across America
The solar eclipse of October 14, 2023, will be annular (ring-shaped) in a narrow path from Oregon to Texas to Central America and northern South America. It will be partial to the northeast and southwest. Yellow curves indicate how much of the Sun is covered by the Moon outside the path of annularity.

On Monday, August 21, 2017, all of North America will have a solar eclipse. The Moon will cover at least part of the Sun for 2 to 3 hours. Halfway through, anyone within a narrow path from Oregon to South Carolina will experience a brief total eclipse. The Moon will completely block the Sun’s bright face for up to 2 minutes 40 seconds. Day will turn into night, and (weather permitting) one of nature’s most awesome sights will become visible: the Sun’s shimmering outer atmosphere, or cor...| Solar Eclipse Across America

As noted in How to View a Solar Eclipse Safely, with one notable exception it is never safe to look directly at the Sun through a telescope, binoculars, or camera lens without a solar filter. That exception is during totality, the total phase of a total solar eclipse, when the dazzlingly bright solar surface is completely blocked by the Moon (which will happen only if you're within the path of the Moon's dark shadow). But totality is fleeting.| Solar Eclipse Across America
Eclipse \i klips′\ (n): the total or partial obscuring of one heavenly body by another.— Merriam-Webster Online Dictionary There’s nothing wrong with the above definition of an eclipse, but it doesn’t begin to convey the thrill and excitement that takes hold of eclipse chasers when the Moon encroaches upon the Sun.| Solar Eclipse Across America

As noted in How to View a Solar Eclipse Safely, looking directly at the Sun is unsafe except during the brief total phase of a solar eclipse (“totality”), when the Moon entirely blocks the Sun’s bright face, which will happen only within the narrow path of totality. To find out whether your home or any other specific location is within the path of totality on April 8, 2024, see Xavier Jubier's Google Map, which supports zooming in to street level.| Solar Eclipse Across America
North America will soon be treated to two major solar eclipses, when the Sun, Moon, and Earth align. On October 14, 2023, anyone under clear skies within a path that sweeps from Oregon to Texas and then through parts of Central and South America will see an annular ("ring") eclipse. Just six months later, on April 8, 2024, a total solar eclipse will sweep from Mexico to Texas to eastern Canada, plunging day into night and revealing the magnificent solar corona for anyone fortunate to be withi...| Solar Eclipse Across America

The solar eclipse of April 8, 2024, will be total in a narrow path from Mexico to Eastern Canada and partial to the northwest and southeast. Yellow curves indicate how much of the Sun is covered by the Moon outside the path of totality. The difference between a total solar eclipse and a partial one is literally the difference between night and day, so get yourself into the path of totality if you can.| Solar Eclipse Across America
