What it is : An annularsolar occultation
Where it is : Over Rapa Nui , also know asEaster Island , in the Pacific Ocean
A “ring of fire” annular solar eclipse as seen on Oct. 2 from Easter Island.
When it was shared : Oct. 2 , 2024
Why it ’s so especial : For up to 7 minute , 25 seconds on Wednesday , Oct. 2 , the new moon appear to sit around perfectly inside the sun ’s diskduring a partial " halo of fire " solar occultation . On both side of that myopic sentence , the edge of the moon appeared to touch the inner border of the sun , causing " Baily ’s bead " — sunlight pelt through the moon ’s quite a little — to fizz . Onlookers had to use solar eclipse glasses and equipment equip with solar filter to safely observe the phenomenon .
circinate solar eclipses dissent from total solar eclipses because the moon is farther from Earth , so the moon ca n’t spread over the sun ’s integral disc . On Oct. 2 , the lunation eclipse 86.9 % of the sun at its top while appear 6.4 % pocket-size than median , according toMoonblink .
However , there are way to fancy the eclipse safely while educe more detail than is potential through regular solar filter . This very special ikon was taken by astrophotographerAditya Madhavanwhile trip with the eclipse duty tour groupAstro Trailsto Easter Island . Madhavan used a Lunt H - alpha scope , which see in only the wavelength of light created by hydrogen atoms on the sunshine .
" We ’re looking at the sunshine ’s range in hydrogen - alpha , and what we ’re find out is the chromosphere of the sunlight , specifically in the wavelength of 656.28 nanometers , " Madhavan evidence Live Science . The sun ’s chromosphere is a thin layer of blood plasma that lies between the Lord’s Day ’s seeable aerofoil , name the photosphere , and the sunshine ’s upper atmosphere , or corposant , whichbecomes seeable to the naked eye during a full solar eclipse .
" It ’s a special variety of filter make out as an h - alpha etalon that isolates that layer of the Lord’s Day ’s ambience , " Madhavan added . The lensman used a Lunt 40 - millimeter atomic number 1 Alpha telescope using a QHY174 monochrome television camera and tracking on a Rainbow Astro RST 135 setting . That allowed him to capturesolar prominences — promising feature exsert outward from the sun ’s surface and into the corona — around the solar limb

In sharp dividing line to the full solar occultation in North America on April 8 , which crossed over about 50 million mass , this eclipse was visible only from within a distant path about 165 to 206 mi ( 265 to 331 kilometers ) wide across remote Patagonia in both Chile and Argentina , where barely 175,000 people live , as well as from Easter Island .

Madhavan observed the eclipse above a spectacular water system - fill volcanic caldera call Rano Kau . From that location , annularity — the moment when the moon appeared to sit within the sunlight with a " ring of flack " circling its edge — last up to 6 moment , 10 seconds .
Although the " ring of fire " was also seeable from part of Patagonia in Chile and Argentina , most eclipse pursuer traveled to Easter Island , some 2,200 mile ( 3,500 kilometre ) off the coast of Chile . It ’s home to roughly 1,000 human - faced moai statues , all staring inland from its coast and reconstruct mainly between 1150 and 1290 . A petite island covering just 63 square miles ( 163 straight kilometer ) , Rapa Nui is not often in the path of solar eclipses . This was Rapa Nui ’s first annular solar eclipse since 1788 and its last until 2345 .
It was Earth ’s first annular solar occultation since Oct. 14 , 2023 , the last until Feb. 17 , 2026 , and the longest until Feb. 6 , 2027 , when a " closed chain of fire " will be visible for 7 minutes , 51 mo from Chile , Argentina , Uruguay , Côte d’Ivoire , Ghana , Togo , Benin and Nigeria , grant toTimeanddate .
