Guwahati: The longest partial lunar eclipse in 580 years will occur on November 19 and will be visible from parts of Northeast India.
The rare phenomenon will be visible from a few areas in Arunachal Pradesh and Assam, Director of Research and Academic at MP Birla Planetarium Debiprosad Duari told PTI.
The partial or Anshik Chandra Grahan or partial lunar eclipse will take place on Kartik Purnima Tithi, Shukla Paksha (November 19) starting at 12:48 PM and will end at 4:17 PM. The maximum partial eclipse will be visible at 2.34 pm as 97 per cent of the moon will be covered by the Earth’s shadow.
“A few areas in Arunachal Pradesh and Assam will experience the last fleeting moments of the partial eclipse just after the moonrise, very close to the eastern horizon,” he explained.
The last time a partial lunar eclipse of such length occurred was on February 18, 1440, and the next time a similar phenomenon can be witnessed will be on February 8, 2669, he said.
The maximum partial eclipse will be visible at 2.34 pm as 97 per cent of the moon will be covered by the Earth’s shadow. The moon is likely to appear blood-red in colour, which happens when the red beams of the sunlight pass through the Earth’s atmosphere and get least deflected and fall on the moon.
The partial Lunar eclipse will be visible from North America, South America, eastern Asia, Australia and the Pacific region.
The penumbral eclipse, which occurs when the sun, earth, and the moon are imperfectly aligned, will begin at 11.32 am and end at 5.33 pm, Duari said.
The penumbral eclipse will be visible from UP, Bihar, Jharkhand, West Bengal and Odisha but it can be seen only briefly from these places, he said.
A penumbral eclipse is not as spectacular and dramatic as the partial eclipse and sometimes does not even get noticed, he said. The last lunar eclipse was on July 27, 2018. The next lunar eclipse will be on May 16, 2022, but it will not be visible from India, Duari said. The next lunar eclipse to be visible from India will be on November 8, 2022.
