Solar eclipse of October 2022: When, where and how to see it on Oct. 25

On Tuesday, Oct. 25, the moon will pass in front of the sun in the last solar eclipse of 2022. Here’s everything you need to know.

On Tuesday, Oct. 25, the moon will pass in front of the sun in the last solar eclipse of 2022 in an event that could be visible to millions of skywatchers lucky enough to be in the visibility path.

The Oct. 25 solar eclipse will be a partial solar eclipse and the second eclipse of the sun of 2022. It will be primarily visible from Europe and parts of Africa and Asia, but you’ll be able to watch online. Learn all about the last solar eclipse of 2022 by the moon in our guide below.


When is the solar eclipse and how to watch online?

The exact time of the Oct. 25 solar eclipse does depend on where you’re observing from. The eclipse itself begins in the Atlantic Ocean at 08:58:20 Universal Time (GMT), which would be about 4:58 a.m. EDT. It will end at 9:01 a.m. EDT (1301 GMT). The moment of peak eclipse will occur at 7 a.m. EDT (1100:09 GMT), according to (opens in new tab) eclipse scientist Fred Espenak.

If you are not in the visibility area, you have several options on how to watch the solar eclipse. Our livestream guide to the Oct. 25 solar eclipse has the full list so far. will have a live webcast that begins at 4:30 a.m. EDT (0830 GMT) and runs through the event. The Ceccano, Italy-based Virtual Telescope Project will have its own webcast beginning at 5 a.m. EDT (0900 GMT) and the Royal Observatory Greenwich will feature live commentary from expert astronomers beginning at 5:05 a.m. EDT (0905 GMT).

What will the partial solar eclipse look like?


At its peak, the Oct.25 solar eclipse will block 82% of the sun as the moon and star will not be perfectly aligned with Earth as they are during a total solar eclipse. That means that at its best, only a sliver of the sun should be visible from “the point of central eclipse.” This prime viewing spot is at the North Pole, so few if any observers will likely see it.

But for observers across Europe and parts of Africa, the Middle East and Asia, the sun will appear obscured to varying degrees depending on how close an observer is to the central path of the eclipse. In Russia, for example, about 80% of the sun’s disk will be covered by the moon, while 70% will appear blocked from western China. Norway and Finland see eclipses 63% and 62%, respectively.

Visibility map for the Oct. 25 solar eclipse


This map of the partial solar eclipse of Oct. 25, 2022 was created by eclipse scientist Fred Espenak of (opens in new tab). The yellow line is the path of greatest eclipse, with the green line showing the extant of visibility to the south. Parts of Greenland and Iceland are positioned for the first encounter with the eclipse.

The partial solar eclipse of Oct. 25 will be visible across large parts of Europe, northeast Africa, the Middle East and central Asia. It will include wide areas of the Arctic, including the North Pole, where few observers are likely to see it.

While this eclipse’s path will begin in the northern Atlantic Ocean, it does cross encompass most of Europe, and wide swaths of Africa and Asia, where millions of skywatchers could potentially see it, weather permitting.

Solar eclipse safe viewing tips


WARNING: Looking directly into the sun can lead to blindness and other forms of permanent eye damage if you aren’t wearing proper eye protection. Always be sure to use proper equipment when observing the sun or a solar eclipse.

If you’re planning to watch the Oct. 25 solar eclipse, or any other sun event, you’ll need to make sure you have the right equipment. Observers should use special protective eyewear or certified eclipse glasses, but here is an important note: REGULAR SUNGLASSES WILL NOT PROTECT YOU, EVEN WITH UV PROTECTION. 


You want to look for eclipse glasses that are ISO-certified, which means they’ve been approved by the International Organization for Standardization as safe for solar observing. That means they’ve been tested so that they do not let any more than 0.00032% of the sun’s light through their light filters, are free of defects like scratches or bubbles, can cover both eyes, and list the name of their manufactures and instructions for proper use.

The safest way to observe a solar eclipse is to use indirect methods, like building a pinhole camera to project the eclipse on an external surface. You can use our guide on how to build a pinhole camera to get started.

Why do solar eclipses occur?

Solar eclipses occur when the moon appears to pass in front of the sun when viewed from Earth. They can only occur when the phase of the moon is in its “new moon” stage, since that’s when the moon is between the Earth and sun. However, the moon’s orbit around Earth is tilted about 5 degrees with respect to the sun, so the two do not align every new moon, which is why there is not a solar eclipse every month.

In a bit of cosmic coincidence, the sun is 400 times bigger than Earth’s moon, but the moon orbits the Earth at a range that is 400 times closer than the sun. When the moon lines up perfectly with the sun, when viewed from Earth, it completely blocks the sun in a total solar eclipse. These happen every 18 months or so.

There are times, however, when the moon appears to cross in front of the sun but not block the star completely. This is when we get partial solar eclipses. Sometimes, the moon is slightly too far from Earth to fully block the sun, creating a dazzling “ring of fire” effect in what is known as an annular solar eclipse.

When is the next solar eclipse?

After the Oct. 25 partial solar eclipse, we’ll have to wait until 2023 for the next time the moon will cross in front of the sun. There are two solar eclipses in 2023.

The next immediate solar eclipse will occur on April 20, 2023 and will be a so-called hybrid solar eclipse. This is an eclipse that can look like an annular eclipse, also known as a ring of fire solar eclipse, from some parts of its track and a total solar eclipse from others. This eclipse will be visible from parts of southeast Asia, the East Indies, Australia, the Phillipines and New Zealand, Indonesia and Papua New Guinea.

After the April 20 solar eclipse, there will be an annular solar eclipse on Oct. 14, 2023. This eclipse will be visible across parts of North America, Central America and South America, with the “ring of fire” effect visible from the western United States, Central America, Columbia and Brazil.

If you can’t wait that long, there will also be a total lunar eclipse on Nov. 8, 2022.
