Kolkata, May 19: A rare Super Blood Moon will be seen in the eastern sky on May 26 evening, just after a total lunar eclipse.
Kolkata had seen its last total lunar eclipse, 10 years ago, on December 10, 2011, Director of M P Birla Planetarium and renowned astrophysicist Debiprasad Duari said Wednesday.
"On the night of May 26, the sun, earth and moon alignment will be such that from earth it will be viewed as a full moon and also eclipsed for some time. Moon on its journey around the earth will be passing through earth's shadow for a few moments and will be totally eclipsed," Duari said.
The total lunar eclipse will be visible mostly from Eastern Asia, Pacific Ocean, most parts of North and South America and Australia.
The partial eclipse of the moon will start at around 3:15 pm and end at 6:22 pm.
For most of India, the moon will be below the eastern horizon during the total eclipse and so people of the country cannot observe a blood moon, but in some parts, mostly from eastern India, people will see only the very last part of a partial lunar eclipse, that is also very close to the eastern horizon when the moon is just rising.
On that evening, the "moon rise in Kolkata will be at 6:15 pm and the interested people will just possibly get a few minutes glimpse of the partial eclipse which will end at around 6:22 pm," he said.
For the other metropolis like Delhi, Mumbai and Chennai the eclipse will not be seen as during the eclipse phase moon will be below the horizon at these places.
"Most of the country will have to be satisfied with a penumbral eclipse, which is not very much discernible with naked eye, when moon passes through a slightly shadowed region of the Earth and is not very spectacular," Duari said.
"But, forgetting the critical COVID-19 situation, people can then see a bright and bigger full moon on that night. At perigee a full moon looks 30 per cent bigger and 14 per cent brighter than an average full moon. That is the reason the full moon will shine brighter and also look bigger on that night," he said.
Moon will be at its perigee on that day exactly at around 7:23 pm, at a distance of 3,57,309 km from Earth.
Explaining the reason behind calling it a blood moon, Duari said as the totally eclipsed moon takes a dark blackish red colour (it) is called a blood moon.
"This happens because of the comparatively less deviation of the red part of the moon light through the earth's atmosphere and falling on the moon's surface," he said.
The next total lunar eclipse will occur on May 16, 2022, but, it will not be visible from the Indian subcontinent.
But on November 8, 2022 a lunar eclipse will be seen from India.

Hong Kong, Oct 25: Amnesty International said Monday it would close its two offices in Hong Kong this year, becoming the latest non-governmental organization to cease its operations amid a crackdown on political dissent in the city.
The human rights group said its local office in Hong Kong would close this month while its regional office will close by the end of the year, with regional operations moved to other offices in the Asia-Pacific region.
This decision, made with a heavy heart, has been driven by Hong Kong's national security law, which has made it effectively impossible for human rights organizations in Hong Kong to work freely and without fear of serious reprisals from the government, Anjhula Mya Singh Bais, chair of Amnesty's board, said in a statement.
Hong Kong implemented a sweeping national security law in 2020 following months of massive anti-government protests. The law outlaws secession, subversion of state power, terrorism and foreign collusion to intervene in the city's affairs. More than 120 people, many of them supporters of the city's democracy movement, have been arrested under the law.
The majority of the city's prominent pro-democracy activists are behind bars for taking part in unauthorized assemblies, and dozens of political organizations and trade unions have ceased operations out of concern for their members' personal safety under the security law.
Bais said the recent targeting of local human rights and trade union groups signaled authorities were intensifying their campaign to rid the city of dissenting voices. It is increasingly difficult for us to keep operating in such an unstable environment, she said.
Critics in Hong Kong say the national security law is an erosion of freedoms, such as those of expression and assembly, that were promised the city for 50 years when the former British colony was handed over to China in 1997.
