The moon will pass in front of the sun in the last solar eclipse of the year on Tuesday (Oct. 25), but you may have to wake up early if you hope to watch it online.
The partial solar eclipse of Oct. 25 is the second and final solar eclipse of 2022 and will be visible to observers across most of Europe, as well as parts of northeast Africa, the Middle East and western Asia. The eclipse begins at 4:58 a.m. EDT (0858 GMT) when the moon first begins to cross the sun as seen from the northern Atlantic Ocean. It will move east over the next four hours, ending at 9:01 a.m. EDT (1301 GMT) just south of India.
If you don't live in those parts of the Earth where the solar eclipse is visible, you do have options to watch it live online. The Royal Observatory Greenwich will host its livestream (opens in new tab) at 5:05 a.m. EDT (0905 GMT) with astronomers commentating on the event. Astrophysicist Gianluca Masi of the Virtual Telescope Project in Ceccano, Italy will also host a livestream (opens in new tab) at 5 a.m. EDT (0900 GMT). Finally, if you really want to wake up early, you can join the TimeandDate.com webcast at 4:30 a.m. EDT (0830 GMT) to see the start of the eclipse.

Exactly how much of the sun will be eclipsed by the moon depends on your viewing location. At its peak, which occurs at about 11:10 a.m. EDT (1510 GMT), the sun will appear 82% covered by the moon to observers near the North Pole. For observers in Russia, about 80% of the sun will be covered, while in China 70% of the sun will be blocked. Even less of the sun, about 62%, will appear blocked to observers in Finland.

As the map above shows, a wide swath of Europe, Asia, the Middle East and northern Africa are in the visibility path for the Oct. 25 solar eclipse. The map, generated by eclipse scientist Fred Espenak of EclipseWise.com (opens in new tab) using Google Maps, shows the path of maximum eclipse as a yellow line, while the full extent of visibility is bordered by the green and purple.
The exact time of the start of the solar eclipse for observers does depend on location.
For example, an eclipse watcher in London can see the start of the eclipse at 10:09 a.m. local time, see maximum eclipse at 10:59 a.m. and see the end of the eclipse at 11:51 a.m. As the eclipse path moves across Earth, those times will be different for each city. In Berlin, the eclipse begins at 11:10 a.m. local time, peaks at 12:14 p.m. and then ends at 1:19 p.m. But in India, where the eclipse visibility path ends, the event will begin for Delhi observers at 4:29 p.m., peak at 5:30 p.m. but its end won't be visible.
Espenak has created a detailed chart solar eclipse times for 38 major cities across Europe, Asia and Africa. You can see that chart at the EclipseWise.com website (opens in new tab) or check out a shorter list below based on Espenak's chart. All times listed are in local time for each city.
|City, Country||Eclipse Begins||Maximum Eclipse||Eclipse Ends|
|London, U.K||10:09 a.m.||10:59 a.m.||11:51 a.m.|
|Berlin, Germany||11:10 a.m.||12:14 a.m.||1:19 p.m.|
|Paris, France||11:13 a.m.||12:03 p.m.||12:55 p.m.|
|Addis Abeba, Ethiopia||11:27 a.m.||11:59 a.m.||12:29 p.m.|
|Cairo, Eqypt||12 p.m.||1:09 p.m.||2:16 p.m.|
|Moscow, Russia||12:25 p.m. .||1:39 p.m.||2:51 p.m.|
|Kyiv, Ukraine||1:23 p.m.||2:37 p.m.||3:50 p.m.|
|Tel Aviv, Israel||12: 58 p.m.||2:11 p.m.||3:22 p.m.|
|Delhi, India||4:29 p.m.||5:30 p.m.||not visible|
|Karachi, Pakistan||3:58 p.m.||5:02||not visible|
If you don't find your city on Espenak's list, don't fret. EclipseWise.com also has a Solar Eclipse Circumstances Calculator for the Oct. 25 eclipse (opens in new tab). There you can find start and stop times for the eclipse, including how high the sun will be in the sky, based on your specific location.
Solar eclipses occur when the moon and sun align as the moon passes between the sun and the Earth. When the moon and sun align completely, the sun appears completely blocked, creating a total solar eclipse, but partial solar eclipses can occur when they don't line up perfectly. Because the moon's orbit around Earth is tilted with respect to the sun, the moon and sun do not align every month to create a solar eclipse.
While Tuesday's solar eclipse is the last eclipse of the sun in 2022 (the first was on April 22), it is not the last eclipse in general. On Nov. 8, the moon will pass through Earth's shadow in a total lunar eclipse that will be visible from most of Asia, Australia, North America, South America and parts of northern and eastern Europe.
The next solar eclipse will occur on April 20, 2023, followed by another on Oct. 14, 2023.
