Now that the “Great North American Eclipse” is over, you may be itching for the next chance to see another celestial wonder. So when is the next solar eclipse?
The next total solar eclipse more than two years out, on August 12, 2026, in Greenland, Iceland and Spain. However, on October 2, 2024“ring of fire” annular solar eclipse passes over parts of the Pacific Ocean, southern Chile and southern Argentina.
While 43.8 million people were able to experience a total for the April 8, 2024, eclipse in North America, only 175,000 people will have that opportunity for the October 2 solar eclipse, according to Time and Date. The paths of both eclipses crossing in the Pacific Ocean.
During an annular solar eclipse, it is NEVER safe to look directly at the sun without solar eclipse glasses designed for solar viewing. Read our guide on how to observe the sun safely.
So, ready to chase an eclipse? Here’s everything you need to know about the annular solar eclipse on October 2, 2024, in Chile and Argentina.
What is an annular solar eclipse?
The October 2 eclipse will be very similar to the annular solar eclipse on October 14, 2023, which was visible across the US Southwest, Central America and South America. All solar eclipses occur when a new moon located exactly between Earth and the sun and casts its shadow on the Earth. However, unlike a total solar eclipse, an annular solar eclipse occurs when the moon a little further from Earth. So, even when the discs align from our perspective, the moon’s shadow does not completely block the sunlight. Instead, a ring of sunlight can be seen around the moon.

The eclipse on October 2, 2024, will have an eclipse magnitude of 0.9326, according to EclipseWise.com. That means around 93% of the sun will be blocked by the moon during the eclipse, resulting in an “annulus” (Latin for “circle”). The moon will appear 6.4% smaller than average, according to MoonBlink.
The closer the observer is to the center line, the more circular the circle of fire will be and the longer it will last. But experienced eclipse watchers often observe from the edge of the path during a minor solar eclipse to see extended views of Baily’s Beads fission around where the limb of the moon appears to touch the sun. They can be visible for several minutes.
Where can you see the October 2 annual solar eclipse?
The ring of fire will only be visible within an annuity path that goes across the Pacific Ocean, southern Chile and southern Argentina.
This area will include the volcanic island of Rapa Nui / Easter Island, an iconic travel destination famous for the mysterious stone sculptures known as moai, some of which reach 40 feet (12 meters) in height and weigh 75 tonnes . The island, which is only 63 square miles (163 square kilometers), is located 2,300 miles (3,700 km) off the coast of Chile, making it the most isolated land mass on Earth where people live Amazingly, this will be the second time a central solar eclipse has been visible from this small Pacific island in recent decades, with a glimpse of a total solar eclipse there. July 11, 2010. The next total and approximate eclipses will be there in 2324 and 2345, respectively.
A good option would be to position yourself just south of moai in several positions to get a view of the ring of fire just above one of the statues, according to the Solar Eclipses Atlas – 2020 to 2045. Iconic locations will include the platform at Ahu Tongariki, where 15 moai are located on a 200-foot-long (60 m) ceremonial platform and nearby Rano Raraku.
The October fire ring will also be visible from southern Patagonia in Chile and Argentina. The route will be between 180 and 185 miles (290 to 300 km) wide.
Where and when can I see the October 2 solar eclipse?
Here are some places eclipse chasers will gather for this annular solar eclipse:
- Rapa Nui / Easter Island, Chile (5 minutes, 38 seconds to 6 minutes, 12 seconds of annuity starting at 14:03 EAST, 67 degrees above North)
- Cochrane, Chile (5 minutes, 40 seconds of superannuation starting at 17:21 CLST, 26 degrees above NNW)
- Perito Moreno National ParkArgentina (6 minutes, 17 seconds of annuity starting at 17:21 ART, 25 degrees above NNW)
- Puerto Deseado, Argentina (3 minutes, 22 seconds of annuity starting at 17:27 ART, 20 degrees above NNW)
- Puerto San Julian, Argentina (5 minutes, 12 seconds of annuity starting at 17:24 ART, 21 degrees above NNW)
Organized eclipse viewing tours include Sky and Telescope, TravelQuest a AstroPaths. All are experienced eclipse tour operators going to Rapa Nui / Easter Island.
What will the weather be like for the October 2nd annual eclipse?
It is always better to travel somewhere you want to visit regardless of the solar eclipse. That certainly applies to the October 2 event, because the forecast of completely clear skies is relatively low. The chance of clouds that day is 75% for Rapa Nui / Easter Island, 90% for Perito Moreno National Park, and 65% to 70% for locations on the Atlantic coast of Argentina, by Time and Date.
On Rapa Nui / Easter Island, land cooling could cause convective clouds to disperse, according to Eclipsophile, with the south coast slightly favored statistically. The chance of seeing the ring of fire is lowest on the Pacific Coast of Chile and highest on the Atlantic coast of Argentina. The latter has the least interesting views of anywhere in the path, but the eclipse will arguably be a more dramatic sight because it will occur much lower in the sky.
Why is the October 2, 2024 annular solar eclipse special?
The October 2, 2024, annular solar eclipse is special for three very different reasons. First, it follows the Great North American Eclipse on April 8 – so interest in solar eclipses should be high, and many eclipse chasers will be traveling to see it.
Second, it’s a long eclipse, with the fire ring lasting up to 7 minutes, 25 seconds. That’s much longer than the 4 minutes, 52 seconds possible in the United States during the last annular solar eclipse on October 14, 2023.
Third, the best place to see this event is a truly iconic destination: Rapa Nui, also known as Easter Island.
