Super Blood Moon in Easter sky on May 26 evening
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.

Pakistan reports two more polio cases; Total tally now 52
ISLAMABAD: At least two more cases of poliovirus were reported in Pakistan, taking the number of infections to 52 so far this year, a report said on Friday.
“The Regional Reference Laboratory for Polio Eradication at the National Institute of Health has confirmed the detection of two more wild poliovirus type 1 (WPV1) cases in Pakistan," an official statement said.
The fresh infections — a boy and a girl — were reported from the Dera Ismail Khan district of Khyber-Pakhtunkhwa province.
“Genetic sequencing of the samples collected from the children is underway," the statement read. Dera Ismail Khan, one of the seven polio-endemic districts of southern Khyber Pakhtunkhwa province, has reported five polio cases so far this year.
Of the 52 cases in the country this year, 24 are from Balochistan, 13 from Sindh, 13 from Khyber Pakhtunkhwa, and one each from Punjab and Islamabad.
There is no cure for polio. Only multiple doses of the oral polio vaccine and completion of the routine vaccination schedule for all children under the age of five can keep them protected.
