Lunar Eclipse

New Delhi, July 27: The longest lunar eclipse or Chandra Grahan of the 21st century will be witnessed on July 27 and early hours of July 28 across the world.

In India, the lunar eclipse will last for one hour and 43 minutes.

The eclipse will start around 11:44 PM IST on July 27 and will occur in different phases. In the first phase, the Moon will fall under the shadow of Earth, which is the penumbral eclipse (initial stage).

While total lunar eclipse is predicted from 1:00 AM IST on July 28. The second phase (Partial) will be visible from around 2:43 AM IST.

The phenomenon will be witnessed across the globe except North America.

The greatest eclipse, when moon will look the darkest, will be at around 01:52 a.m. and the totality will continue at 02:43 a.m. after this period the moon will remain partially eclipsed till 03:49 a.m. of July 28,” said Debiprosad Duari, Director, Research & Academic, M.P. Birla Planetarium, Kolkata.

The moon will also be a ‘Blood Moon,’ where the sunlight passing through the Earth’s atmosphere, break down in its constituent colours and the red part gets scattered by the atmosphere and falls on the Moon’s surface, thereby making it take on a reddish copper hue.

Earlier this year, the world had a glimpse of total lunar eclipse on January 31.

The previous total lunar eclipse lasted 1 hour and 16 minutes when the moon passed to the south of shadow’s centre.

The July 27 lunar eclipse will be the longest till June 9, 2123 as a result of many factors.

The Moon will be at the farthest point from Earth in its orbit which will make it appear  in a smaller size than regular.
