First lunar eclipse of the year on cards on Jan 10

Kolkata: The first celestial event of 2020, a penumbral lunar eclipse, will take place on January 10 and skywatchers will be able to witness the phenomenon from all corners of India, including West Bengal.

The eclipse will begin at 10.37 pm on January 10 and will end around 2.42 am on January 11, the Director of M P Birla Planetarium, Debiprosad Duari, said in a statement on Wednesday.

The lunar eclipse on Friday will be the first of four penumbral lunar eclipses that will take place this year, Duari said, adding, the other three penumbral lunar eclipses will occur on June 5, July 5 and November 30.

The penumbral lunar eclipse will also be visible from different countries in Asia, Africa, Australia, and Europe, he said.

In a normal lunar eclipse, the moon passes through the central part of the earth’s shadow called umbra, and one witness considerable darkening of the lunar disc. But in case of January 10 penumbral lunar eclipse there will be only a slight dimming of the lunar surface, the statement quoted Duari as saying.

“To a naked eye it is sometimes a little difficult to recognise a penumbral lunar eclipse, though it is interesting to see the larger than usual appearance of the moon, and the shifts in shadow during the 4-hour period,” the renowned astrophysicist said.

Asked if the event would be clearly visible from Kolkata, Duari said, Skygazers across the state, including Kolkata, will be able to witness the celestial event only if the weather does not play a spoilsport.
