New Delhi, March 20: Marking the beginning of spring, the Sun will cross the plane of the Earth’s equator tomorrow morning, making day and night of approximately the same duration.
The event known as equinox is eagerly awaited by space enthusiasts as it takes place only twice a year, on March 21 and September 23.
On the equinox, the sun moves across the celestial equator, which lies directly above the Earth’s equator.
When the Sun crosses the plane, it rises exactly in the east and sets exactly in the west.
“This year the phenomenon (vernal equinox) will take place at 4:51 AM (23:21 UT),” Science Popularisation Association of Communicators and Educators (SPACE) President Chander Bhushan Devgun said.
SPACE, an NGO, has planned a programme at Jantar Mantar in New Delhi on the occasion.
Telescopes and solar filters will be set up for solar observations.
