Few natural phenomena compare to the grandeur and wonder of a solar eclipse. When celestial bodies in the solar system align perfectly, sunlight—the vital source of warmth enabling life—is briefly obstructed. Such occurrences continue to evoke profound reactions, including fear rooted in religious beliefs and, for some individuals, significant confusion.
However, expectations for a breathtaking spectacle on the upcoming Tuesday should be tempered. Although the moon will partially obscure the Sun, this event is predicted to be relatively underwhelming, with very few individuals having the opportunity to witness it.
In contrast to a total solar eclipse, where the Moon fully masks the Sun as observed from specific locations on Earth—as seen during the eclipse in April—the event on October 2 will be an annular eclipse. During this type of eclipse, the Moon will cover part of the Sun when it is at its farthest distance from Earth in its orbit, known as apogee. Consequently, the Moon does not entirely cover the Sun, creating a distinctive “ring of fire” effect, a phenomenon named from the Latin word “annulus” for ring. Even though this event will occur shortly before the Moon reaches apogee, leading to a smaller portion of the light being blocked, the Sun will still be approximately 86% obscured at the eclipse’s peak, according to EarthSky.
Regrettably, the visibility of this annular eclipse will be limited due to its trajectory, unlike the April total eclipse, which presented an optimal viewing path for many sky enthusiasts. The eclipse’s route will trace a curve across the Pacific Ocean. According to NASA, the annular phase will be observable only in certain areas of Argentina, Chile, and Rapa Nui (formerly Easter Island). Outside these specific locations, observers may witness a partial eclipse, characterized by a crescent-shaped Sun. This partial eclipse will be viewable in portions of western Mexico, various Pacific Islands such as American Samoa and Hawaii, and parts of South America, including regions of Brazil, Uruguay, and Paraguay. Unfortunately, observers in the continental United States will not be able to see the eclipse.
The partial eclipse will commence at 3:42 p.m. Coordinated Universal Time (UT) on October 2, equivalent to 11:42 a.m. Eastern Time (ET). The annular phase will begin at 4:50 p.m. UT (12:50 p.m. ET) and will conclude at 8:39 p.m. UT (4:39 p.m. ET).
Despite the potentially underwhelming nature of this eclipse, safety remains paramount. Proper eye protection, such as eclipse glasses or solar viewers tested for compliance, is essential. Staring directly at the Sun without these precautions can result in permanent eye damage. Those without appropriate eyewear can still observe the eclipse indirectly: using a small hole in a piece of paper or index card to project the eclipse’s shadow onto the ground, with the Sun positioned behind them.
