Honestly, if you missed the big total eclipse back in April, you probably think the "main event" for 2024 is over. You've seen the photos of the diamond ring effect and the sudden darkness, and maybe you figure anything else is just a consolation prize. But that’s a mistake. On October 2, 2024, a massive "Ring of Fire" is going to cut across the Pacific and South America, and it's fundamentally different from what we saw earlier this year.
This is an annular eclipse.

Basically, the Moon is a bit too far away from Earth to block the Sun completely. It’s at "apogee," the far point of its orbit. Instead of a total blackout, you get this piercing, perfect circle of light around the Moon’s silhouette. It looks like a portal in the sky. If you're in the right spot, it's actually more visually jarring than a total eclipse because the Sun never truly "goes away"—it just transforms into a thin, golden wire.
Where the Ring of Fire actually hits land
Most of this eclipse is happening over the ocean. It starts south of Hawaii and treks across the Pacific, which is why it's kind of a "hidden" event for most people in the Northern Hemisphere. If you want to see the actual annulus—the ring—you’ve got to be in a very specific, narrow path.
The Easter Island Magic
The most incredible spot to witness this is Rapa Nui, or Easter Island. Imagine standing next to those massive Moai statues while a golden ring hangs in the sky above them. On October 2, the "ring" phase will last about 6 minutes and 23 seconds there. That is a massive amount of time for an eclipse.
Chile and Argentina
After it leaves Easter Island, the shadow hits the Patagonian coast of Chile and then moves into Argentina.
- Chile: It hits the coast around 20:22 UTC.
- Argentina: It crosses the Andes and passes over places like Perito Moreno National Park.
- The Path: The track is about 165 to 206 miles wide. If you're even a mile outside that line, you don't see the ring; you just see a deep crescent.
It's not "just" a partial eclipse
A lot of people think that because it isn't "total," it doesn't matter. That's wrong. During the solar eclipse October 2, the Sun will be roughly 93% covered at its peak.
Even though 7% of the Sun is still visible, the light changes in a way that feels... oily. Shadows get incredibly sharp. If you look under a leafy tree, the gaps between the leaves act like pinhole projectors, and you’ll see thousands of little golden rings dancing on the ground.
NASA experts and climatologists like Jay Anderson have noted that the Argentinian side of the Andes actually offers the best weather prospects for this. The mountains tend to "squeeze" the moisture out of the air, giving you a much higher chance of clear skies compared to the damp, cloudy Pacific side.
The safety mistake that ruins eyes
Here is the most important thing: you cannot take your glasses off.
During a total eclipse, there’s a few minutes of "totality" where it’s safe to look with the naked eye. That never happens on October 2. Because it’s an annular eclipse, a piece of the Sun’s actual surface is always visible. That "Ring of Fire" is still bright enough to cook your retinas.
You need ISO 12312-2 certified solar filters. No, stacked sunglasses don't work. No, a potato chip bag doesn't work. If you’re using a telescope or a long camera lens, the filter must be on the front of the lens. If you put eclipse glasses over your eyes and then look through an unfiltered telescope, the lens will act like a magnifying glass and melt the glasses (and your eye) in about a second.

What about the rest of us?
If you aren't in Patagonia or on a remote Pacific island, you’ll probably see a partial eclipse if you're in the southern half of South America, Hawaii, or even parts of Antarctica.
- Hawaii: You'll see about a 50% "bite" taken out of the Sun early in the morning.
- Buenos Aires/Santiago: You'll get a deep partial eclipse, where the Sun looks like a thin sliver.
It’s a weird sensation. The birds might stop singing for a bit. The temperature will definitely drop—sometimes by as much as 10 degrees Fahrenheit—as the solar radiation dips.
Actionable steps for the October 2 eclipse
If you’re planning to track this or just want to see what the fuss is about, here’s what you actually need to do:
- Check your location's timing: Use a site like TimeAndDate or NASA’s eclipse explorer. The event happens in UTC, so you have to convert it to your local time. For Easter Island, the peak is roughly mid-afternoon.
- Inspect your gear now: If you have glasses left over from April, check them for scratches. Hold them up to a bright lightbulb. If you see even a pinprick of light through the black polymer, throw them away.
- Plan for "Baily's Beads": If you are right on the edge of the path (the "limit" line), you might see more of the "Baily's Beads" effect, where sunlight sparkles through the mountains and craters of the Moon. It’s a trade-off: you get a shorter "ring" time but more of these sparkling "beads."
- Photography prep: If you’re shooting this, you need a solar filter for your lens. Period. Without it, you’ll fry your camera sensor. Practice your focus on the sun a few days before (with the filter on!) so you aren't fumbling when the light starts to fade.
This October event is the final solar eclipse of 2024. It’s a long one—over seven minutes of annularity at its greatest point—making it one of the most significant "Ring of Fire" events of the decade. Even if you aren't in the path of annularity, the partial phases are a reminder of the clockwork precision of our solar system.
