If you have binoculars or a telescope available, they will enhance the views and reveal details on the Moon’s surface when basking in Earth’s shadow.Go outside and enjoy the view with your own eyes, binoculars, or a telescope! You won’t need special equipment or safety glasses.Research the time and date for the entire lunar eclipse for your area and follow along as the eclipse progresses.The umbral shadow has a bluish, very bright rim L = 4 Very bright copper-red or orange eclipse.The umbral shadow usually has a bright or yellow rim. We see a very dark central shadow while the outer edge of the umbra remains relatively bright. L = 2 Deep red or rust-colored eclipse.Details are distinguishable only with difficulty. L = 1 Dark eclipse, gray or brownish in coloration.The Moon is almost invisible, especially during mid-totality. The scale contains five “L values” from 0 to 4. In 1921, French astronomer André-Louis Danjon came up with the five-point Danjon Scale to measure the appearance and brightness of the Moon during a total lunar eclipse. Penumbral eclipse ends (sixth contact): The Moon leaves the Earth’s lighter shadow.Partial eclipse ends (fifth contact): Earth’s umbra completely leaves the Moon’s surface.Total eclipse ends (fourth contact): Earth’s umbra moves away from the Moon’s outer limb.Maximum eclipse (peak stage): The Moon moves as far into the umbra as possible.Depending on atmospheric conditions, the Moon can take on different colors, such as red, orange, yellow, or brown. Total eclipse begins (third contact): The Moon moves entirely inside the Earth’s umbra.Partial eclipse begins (second contact): Earth’s umbra begins to cover the Moon, making the eclipse more noticeable. ![]() Penumbral eclipse begins (first contact): The Moon enters the Earth’s lighter shadow.If you have time and are in an ideal location, why not try to watch a partial or total lunar eclipse from start to finish, including when the Moon enters and exits the penumbra? Here are the seven stages of a total lunar eclipse to watch for: Under favorable conditions, the Moon can remain in the umbra in a total eclipse for almost two hours.Ī lunar eclipse is one of the easiest celestial events to observe. Lunar eclipses last several hours from start to finish. The Moon moves into the Earth’s shadow-first, a lighter shadow called the penumbra, and then a darker shadow called the umbra. A lunar eclipse can occur only during a full Moon when the Sun, Earth, and Moon are aligned. Every so often, its shadow falls upon the Moon. On Earth, we can only see the Moon because it reflects sunlight. The Moon does not give off light of its own. If you are curious to learn more about lunar eclipses and the details of November’s total lunar eclipse, read on! Start planning your evening now to have a great view of one of nature’s grandest nighttime spectacles. How bright or dark will the Moon be? What color will the Moon appear? You will have to see the eclipse to find out. The Moon will traverse through the Earth’s umbral or darker shadow, exciting those watching in person or on the Internet. On November 7-8, 2022, the second of two total lunar eclipses of the year will occur. Because they are not limited to a narrow path of totality, many more observers can enjoy total lunar eclipses for much longer. But unlike solar eclipses, lunar eclipses do not require special protective filters or other specialized gear. Total lunar eclipses are not as exciting as total solar eclipses, which turn day into “night” and back again. Rather than stoking fear, lunar eclipses delight modern-day observers. They understand eclipses and can predict them well in advance. Today, scientists comprehend the orbital mechanics of our Solar System. Surely, they thought, it was a bad omen and a harbinger of hardship and misery. They believed the gods were angry and had taken the regular Moon away as punishment. The appearance of a red Moon frightened many ancient observers. The shadow retreats or completely engulfs the Moon until it takes on an eerie red hue. Slowly, a curved shadow appears, taking a “bite” from the Moon’s disk. You may have noticed that the full Moon sometimes undergoes a startling transformation.
