The annular portion of the eclipse will not be seen from land. Totality will sweep across Earth to the northeast-passing over small regions of Australia, East Timor and Indonesia-and shift back to an annular eclipse between Indonesia and Hawaii. The annular eclipse will first appear over the Pacific south of Madagascar, then switch to a total eclipse while still over water. This week, the hybrid eclipse will occur as a combination of all three other types of eclipses. In this way, a total eclipse and an annular eclipse can be seen in different places around the world. During a hybrid eclipse, different vantage points on Earth see the moon appear as different sizes due to our planet’s curved surface putting some viewers farther from the moon, writes Time’s Jeffrey Kluger. As a result, it passes between the Earth and sun at varying distances, creating a visual effect of a larger or smaller moon. These differences exist because the moon’s orbit is not a perfect circle, but rather an oval-shaped ellipse. A partial eclipse happens when the sun is only partly covered by the moon. And a hybrid eclipse is a combination of these other types. In a total eclipse, the moon is in full alignment with the sun, blocking the entirety of the star’s brightness and casting a shadow over parts of our planet. An annular eclipse with a ring around the moon occurs when the moon is farther from the Earth and appears smaller than the sun in the sky. But although the moon orbits Earth once every 27.3 days, an eclipse does not happen with every revolution-since the moon’s orbit is tilted by five degrees relative to Earth’s, it usually appears to pass above or below the sun from our point of view.īut on the special occasions when the moon and sun do align in the sky, one of four spectacular outcomes can happen: an annular, total, partial or hybrid solar eclipse. The Moon is in the constellation Cancer.Solar eclipses occur when the moon passes directly between the sun and the Earth. Because of parallax, the Moon's position against the background stars will look a bit different for observers at different locations on the surface of the Earth. The view in this animation is geocentric. An hour later, entirely within the umbra, the Moon is a ghostly copper color, and this lasts for over an hour before the Moon begins to emerge from the central shadow. The real action begins when the Moon starts to disappear as it enters the umbra at about 3:48 a.m. The Moon's appearance isn't affected much by the penumbra. The umbra is where the Sun is completely hidden. The penumbra is the part of the Earth’s shadow where the Sun is only partially covered by the Earth. Australia, Indonesia, Southeast Asia, China, Mongolia, Russia, Japan, Korea, and India are all well-placed for viewing totality. Areas west of the Mississippi River see at least part of the total phase, while for those to the east, the Moon sets before the main event begins. This animation shows the changing appearance of the Moon as it travels into and out of the Earth's shadow, along with the times at various stages.Īlaska and Hawaii are in the best positions in the U.S. In the early morning of January 31, 2018, the Moon enters the Earth's shadow, creating a total lunar eclipse, the first since September of 2015.
