Clouds, dust, ash, photochemical droplets and organic material in the atmosphere can change how much light is refracted into the umbra. Credit: NASA | + Enlarge imageĪ variety of factors affect the appearance of the Moon during a total lunar eclipse. Should you decide to skip this part of the eclipse, you won’t miss much.Īs the Moon moves completely into the umbra, it turns a reddish-orange color. Because this part of Earth’s shadow is not fully dark, you may only notice some dim shading (if anything at all) on the Moon near the end of this part of the eclipse. The Moon will dim very slightly for the next 67 minutes as it moves deeper into the penumbra. EST), the edge of the Moon will begin entering the penumbra. will see the Moon set below the horizon as it exits Earth’s shadow in the second half of the eclipse.Īt 12:02 a.m. Viewers in the most eastern parts of the continental U.S. 8, 2022, which will be visible in North and South America, as well as Asia and Australia. Here's what to expect during the total lunar eclipse on Nov. The inner part of the shadow, known as the umbra, is much darker because Earth blocks additional sunlight from entering the umbra. (You have probably noticed that some shadows on the ground are darker than others, depending on how much outside light enters the shadow the same is true for the outer part of Earth’s shadow). The penumbra is less dark than the inner part of the shadow because it’s penetrated by some sunlight. The outer part of the cone-shaped shadow is called the penumbra. The Moon passes through two distinct parts of Earth’s shadow during a lunar eclipse. Here's how and where to watch one of the sky’s most dazzling shows when the Sun, Earth, and Moon align, creating a total lunar eclipse. These comparisons helped scientists determine the rate at which Earth’s rotation is slowing. When Hipparchus saw that the stars’ positions had indeed moved, he knew that Earth must wobble on its axis!Īdditionally, modern-day astronomers have used ancient eclipse records and compared them with computer simulations. If Earth didn’t wobble, the stars would appear to be in the same place they were hundreds of years earlier. A lunar eclipse allowed him to see the stars and know exactly where the Sun was for comparison – directly opposite the Moon. Greek astronomer Hipparchus made this discovery by comparing the position of stars relative to the Sun during a lunar eclipse to those recorded hundreds of years earlier. Earth completes one wobble, or precession cycle, over the course of 26,000 years. He realized that only if Earth were a spheroid would its shadows be round – a revelation that he and others had many centuries before the first ships sailed around the world.Įarth wobbles on its axis like a spinning top that’s about to fall over, a phenomenon called precession. In ancient Greece, Aristotle noted that the shadows on the Moon during lunar eclipses were round, regardless of where an observer saw them. Lunar eclipses have long played an important role in understanding Earth and its motions in space. NASA’s player is also embedded below.Explore our collection of standards-aligned lessons for grades 1-12. “If we’re going to see a chance to actually catch a glimpse of that solar eclipse, we’re going to have to really keep our fingers crossed that some of these breaks in the clouds become a bit wider and actually stick for a while longer,” said John Mayer, chief meteorologist at KATU’s sister station KVAL in Eugene.īut all is not lost. More Information: Great American Eclipseīut viewers in Eugene and Roseburg will most likely find themselves seeing little sun and mostly clouds.The path of annularity will cut a diagonal swath through Oregon, allowing viewers in places like Eugene, Roseburg, Medford and Klamath Falls to see “the ring of fire.” PDT and will race across the land faster than 7,534 mph. Saturday's annular eclipse begins near Reedsport at 9:13 a.m. In an annular eclipse, the moon covers most of the sun but leaves a ring of light. He said in the Klamath Falls and Lakeview areas, the skies will be partly cloudy to fair.Īn annular eclipse is different than a total eclipse, where the moon completely covers the sun. “On the east side, say south of La Pine, down towards Klamath Falls - pretty good chance of seeing the annular eclipse,” said KATU Meteorologist Dave Salesky on Friday. That’s because west of the Cascades the skies will likely be filled with clouds. If you want to see the annular solar eclipse that will pass through Oregon Saturday morning, being on the east side of the Cascades will give you your best shot.
