The world will witness the longest total lunar eclipse of this century on July 27, 2018. It will be on the intervening night of July 27 and 28 with a duration of 1 hour and 43 minutes, making it the longest one. Lunar Eclipse and Solar Eclipse, referred to as Chandra Grahan and Surya Grahan respectively, hold special significance in the Hindu calendar.
India will be able to witness the entire event. In India, the lunar eclipse is referred to as Chandra Grahan.
The first part of the lunar eclipse will see the Moon fall partially under the Earth’s shadow, which should start around 11.44 pm IST on July 27. When this happens, the Moon will not be visible and a partial lunar eclipse sets in, which will peak at 11.54 pm.
This is also time when the Moon will turn red at the highest point of the eclipse. The total lunar eclipse will last till 2.43 am, after which the Moon will begin to move outside the Earth’s shadow. After 2.43 AM IST on July 28, we will witness another partial lunar eclipse as Moon continues on its orbit, and pulls away from the Earth’s shadow also known as the Umbra. Remember, a total lunar eclipse only takes place when the Sun, Earth and Moon are aligned and the Earth completely blocks sunlight from reaching the satellite.
