map showing the path of the annular solar eclipse across Earth, only crossing land at south america.
Earth is roughly spherical, and so is the moon. When the moon’s shadow strikes Earth, it does so obliquely as a stretched oval, becomes more circular at the point of greatest eclipse, and then stretches again.
You have to be in the path of the moon’s “antumbra” shadow — from where the moon will appear entirely within the sun’s disk — to see the ring of fire. Your experience depends on where along the path you are located and how close you are to its centerline. The closer you are to the centerline, the longer the ring of fire will be visible.
Maximum annularity at sunrise
As the eclipse begins at sunrise south of Hawaii in the Pacific Ocean around 5:43 a.m. local time (11:43 a.m. EDT or 1543 GMT), the moon’s shadow will be at its farthest — and thus its widest — from Earth. The path of annularity — the width of the moon’s shadow — will be 206 miles (332 km) when it first appears on Earth. Here, the ring of fire will last 5 minutes, 34 seconds.
Point of greatest eclipse
About 3 hours and 4,400 miles (7,100 km) later is the point of the greatest eclipse, where annularity will last 7 minutes, 25 seconds beginning around 10:45 a.m. local time (2:45 p.m. EDT or 18:45 GMT) over the empty ocean.
At this point, the moon will be as close to Earth as it will get during the eclipse and where the centers of the moon, Earth and the sun are perfectly aligned. Here, the path of annularity will be 165 miles wide — the narrowest it will get during the solar eclipse.
Maximum annularity at sunset
As the “ring of fire” phase of the eclipse ends at sunset in the southern Atlantic Ocean at 5:39 p.m. local time (4:39 p.m. EDT or 20:39 UTC ), the moon’s shadow will again be as far from the moon as it will get. The path of annularity here will be 206 miles (332 km) wide when it last appears on Earth. This final view of the ring of fire will last 5 minutes, 41 seconds.
