This year's first partial lunar eclipse will occur on June 26 when more than 50 per cent of the full moon disc will be under the earth's shadow, but it will be visible only in the Northeast in India.
"The moon will rise in Kolkata approximately at 6:25 pm, but only the end phase of the eclipse will be visible in the Northeast, including Assam," M P Birla Planetarium director (Research and Academics) Debiprosad Duari said on Thursday.
The eclipse will be visible in Eastern Asia, Australia, Antarctica, parts of America and the Indian and the Pacific Oceans, he said.
The partial lunar eclipse will start at approximately 3.46 pm and continue till 6:20 pm, during which more than 50 per cent of the moon will be within the main umbral shadow.
Kolkatans last viewed a lunar eclipse on December 31, 2009. The next lunar eclipse will occur on December 21 this year in India.
Sky-watchers in India will have to wait till June 15, 2011 to witness a total lunar eclipse, Duari said.
