Skygazers are in for a celestial delight as the longest partial lunar eclipse of the century on Friday is likely to turn the moon to a red-brown hue, despite not being a blood Moon. Lunar eclipses occur when the moon passes into the Earth's shadow. It the longest such eclipse in nearly 600 years but will be visible at to only those living in North and South America, Eastern Asia, Australia, and the Pacific Region, according to NASA.
The lunar eclipse began at 1.02 a.m. EST on Friday (11.32 a.m. IST) and will goes on till 7.04 a.m. EST (5.34 p.m. IST). At 3.45 a.m. EST, more than 95 per cent of the Moon's disk will be in the umbra or the darker part of the shadow, and the Moon will appear red. The colour might be easier to see in binoculars or a telescope. The eclipse will peak at 4.03 a.m. EST -- the best time to see the red colour.

By 4.20 a.m. EST, the redness will fade as less than 95 per cent of the Moon will be the Earth's umbra. It appears that a bite is taken out of the opposite side of the Moon from earlier. "During a lunar eclipse, the moon turns red because the only sunlight reaching the moon passes through Earth's atmosphere," NASA said about the Beaver Moon eclipse. "The more dust or clouds in Earth's atmosphere during the eclipse, the redder the moon will appear. It's as if all the world's sunrises and sunsets are projected onto the moon."
NASA said this partial eclipse is ultra-long because the moon is almost at the farthest part from the Earth in its orbit (known as apogee), which means the moon is moving a bit slower through the shadow of Earth. Also, the fact the eclipse is almost total means "the moon spends a longer amount of time in the Earth's umbra than it would in a 'more-partial' eclipse", NASA stated.
"It's actually the longest partial lunar eclipse in a millennium, clocking in at three hours, 28 minutes and 23 seconds...and will remain the longest partial lunar eclipse for 648 years until February 8, 2669 (three hours, 30 minutes, and two seconds)." There hasn't been a longer partial lunar eclipse since February 18, 1440 (three hours, 28 minutes, 46 seconds). The next time a long total lunar eclipse will take place on November 8, 2022, the space agency said. (IANS/ MBI)

Skygazers are in for a treat as the longest partial lunar eclipse of the century is going to take place on November 19. It is also the longest such eclipse in nearly 600 years. Lunar eclipses occur when the moon passes into the Earth's shadow. In this case, the partial eclipse phase will last 3 hours, 28 minutes and 24 seconds, and the full eclipse for 6 hours and 1 minute, making it the longest partial eclipse in 580 years, according to Indiana's Holcomb Observatory, located on the campus of Butler University in the US. "Longest partial eclipse of the century to occur in the pre-dawn hours of November 19th. This will also be the longest partial lunar eclipse in 580 years!" the observatory tweeted.
Sky observers will get a view of a subtly changing moon, which may even take on a reddish hue. This will also be the last lunar eclipse of the year. According to NASA, the event will begin at approximately 2.19 a.m. EST (12.49 p.m. India time) on Nov 19. The US space agency said that the eclipse will take place in four main phases -- at 1.02 a.m. EST the moon will enter the penumbra, or the lighter part of the moon's shadow. This phase is usually hard to spot without special equipment because the darkening is so slight.

The moon will then arrive at the umbra, or the darker part of the shadow, at 2.18 a.m. EST. For about 3.5 hours the moon will pass through the deep shadow until it exits the umbra at 5.47 a.m. The eclipse will end at 6.03 a.m. EST. The maximum eclipse will take place at 4.03 AM EST, when 97 per cent of the moon's face covered by the deepest part of the Earth's shadow will probably turn a deep red, the observatory said.
November's full moon is traditionally known as the Beaver Moon, as beavers are preparing for winter, hence this month's event's Beaver Moon eclipse moniker. At least part of the eclipse will be visible in North and South America, Eastern Asia, Australia, and the Pacific Region, NASA said. For US East Coast observers, the partial eclipse begins a little after 2 a.m., reaching its maximum at 4 in the morning. For observers on the West Coast, that translates to beginning just after 11 p.m., with a maximum at 1 a.m.
"Partial lunar eclipses might not be quite as spectacular as total lunar eclipses -- where the moon is completely covered in Earth's shadow -- but they occur more frequently. And that just means more opportunities to witness little changes in our solar system that sometimes occur right before our eyes," NASA said. (IANS/ MBI)

A partial eclipse of the moon will occur on November 19 and a small span of the partial phase of the eclipse towards the end would be visible from parts of Arunachal Pradesh and Assam.
"The partial phase of the eclipse will begin at 12.48 p.m. and will end at 4.17 p.m.," the India Meteorological Department (IMD) said on Thursday.
Apart from these two states in India, the eclipse will be visible from western Africa, western Europe, North America, South America, Asia, Australia, the Atlantic Ocean and the Pacific Ocean.
According to IMD sources, the next lunar eclipse will be visible from India on November 8, 2022. It will be a total lunar eclipse.
Lunar eclipse occurs on a full moon day when the Earth comes in between the Sun and the Moon and when all the three objects are aligned. A total lunar eclipse will occur when the whole Moon comes under the umbral shadow of the Earth and the partial lunar eclipse occurs when only a part of the Moon comes under the umbral shadow of the Earth, a release from the Ministry of Earth Sciences said.

Here comes a total lunar eclipse and supermoon, all wrapped into one.
The moon, Earth and sun will line up this weekend for the only total lunar eclipse this year and next. At the same time, the moon will be ever so closer to Earth and appear slightly bigger and brighter than usual — a supermoon.
“This one is particularly good,” said Rice University astrophysicist Patrick Hartigan. “It not only is a supermoon and it’s a total eclipse, but the total eclipse also lasts pretty long. It’s about an hour.”
The whole eclipse starts Sunday night or early Monday, depending on location, and will take about three hours.
It begins with the partial phase around 10:34 p.m. EST Sunday. That’s when Earth’s shadow will begin to nip at the moon. Totality — when Earth’s shadow completely blankets the moon — will last 62 minutes, beginning at 11:41 p.m. EST Sunday.
If the skies are clear, the entire eclipse will be visible in North and South America, as well as Greenland, Iceland, Ireland, Great Britain, Norway, Sweden, Portugal, and the French and Spanish coasts. The rest of Europe, as well as Africa, will have partial viewing before the moon sets.
During totality, the moon will look red because of sunlight scattering off Earth’s atmosphere. That’s why an eclipsed moon is sometimes known as a blood moon. In January, the full moon is also sometimes known as the wolf moon or great spirit moon.
So informally speaking, the upcoming lunar eclipse will be a super blood wolf — or great spirit — moon.
In the U.S., the eclipse will begin relatively early Sunday evening, making it easier for children to stay up and enjoy the show. Plus the next day is a federal holiday, with most schools closed. But the weather forecast for much of the U.S. doesn’t look good.
Parents “can keep their kids up maybe a little bit later,” said, Hartigan, who will catch the lunar extravaganza from Houston. “It’s just a wonderful thing for the whole family to see because it’s fairly rare to have all these things kind of come together at the same time.
“The good thing about this is that you don’t need any special equipment,” he added.
Asia, Australia and New Zealand are out of luck. But they had prime viewing last year, when two total lunar eclipses occurred.
The next total lunar eclipse won’t be until May 2021.
As for full-moon supermoons, this will be the first of three this year. The upcoming supermoon will be about 222,000 miles (357,300 kilometers) away. The Feb. 19 supermoon will be a bit closer and one in March will be the farthest. (VOA)
