On Sunday, Aug. 21, people around the world will see a total solar eclipse unfold, with the moon passing in front of the sun and casting a shadow on Earth. On Monday, Aug. 21, the total eclipse will occur over a four-hour period, making it a true show. How do we know when it will happen? There are two different eclipse-tracker events. Eclipse North America plans to track the total eclipse and the totality over land on Aug. 21. While eclipse Latin America is focused more on the eastern-most part of the eclipse, coming ashore Aug. 20 and 21.
Where and When is the Total Solar Eclipse? The total solar eclipse will begin at 5:24 p.m. EDT (2:24 p.m. MDT), and conclude at 9:11 p.m. EDT (5:11 p.m. MDT), making it visible from Mexico to southern Europe, the Middle East, Afghanistan, India, South Asia, Papua New Guinea, Hawaii, and eastern Russia.

When to watch it? On Sunday, Aug. 21, no eclipse will begin in North America. Between 11:15 a.m. and 4:00 p.m. EDT, in the eastern United States, the eclipse will occur, during which the sun will be blocked completely or very nearly so. As the moon passes through the center of the sun, it will cast a shadow that ranges in size from 11,500 miles to more than 15,000 miles in diameter, making the eclipse visible from a large swath of the United States and as far north as the Aleutian Islands.
Will we see it in person? Look no further than your own backyard, or watch it online — your question, however, will probably be the same as mine: Where and when?

As the North American eclipse wraps up, eclipse Latin America will launch. As the eclipse moves away from the northern United States, its path will roll over the eastern and central Caribbean.

Why watch the total solar eclipse? It will be the first total solar eclipse since 1994. Total solar eclipses are not as rare as you might think: There are 10 total solar eclipses slated for 2021-22, but none are as long as the 2021 eclipse. A total solar eclipse lasts about three minutes and 15 seconds.
Can’t you see solar eclipses through binoculars, as astronomers say? Not really. Viewing a solar eclipse through binoculars requires looking at it with a lens the size of a fingernail. Solar filters to protect your eyes during the viewing of the solar eclipse are available for sale. A pair of reading glasses are also recommended. There is a special paper offered for observers who happen to have eclipse glasses. Also useful are some special pinhole projects, which you can find online. The eclipse will occur in a region of space — space with holes in it. This means that scientists will be able to observe the sun through a microscope during the total eclipse, whether they have solar filters or not.
What’s the chance of a partial solar eclipse? A partial solar eclipse occurs when the moon’s shadow is less than 90 percent of the diameter of the sun. The most recent partial solar eclipse that observers could directly see occurred on Feb. 11, 2016. The next will occur on March 16, 2020.
Where in the United States will we see the partial solar eclipse? Total solar eclipses are usually accompanied by a partial solar eclipse. The north reaches of Oregon and Washington state will see a partial solar eclipse at 2:22 p.m. EDT on Monday, Aug. 21. The most likely place in the Midwest to see a partial solar eclipse is Missouri, where it will occur at 11:24 a.m. EDT, as illustrated by the composite image below.
