 A rare celestial event , annular solar eclipse will give a special visual treat in the Eastern Hemisphere in this weekend will coincide with the longest day of the year in this week. This is a rare astronomical event occurring second time since 1982 , that these events takes place on the same day.

The annular solar eclipse will come on Sunday,21 June ,characterized by a ring of fire on the sky due to the edges of the sun around the moon, but it’s not a total eclipse.

“Annular eclipses are similar to total eclipses in which the moon, earth and sun are aligned so that the moon moves directly in front of the sun as viewed from  Earth,” said Alex Young, associate director for science in the heliophysics science division at NASA’ s Goddard Space Flight  Centre.

The total annular solar eclipse occurs when the moon is too far away in its orbit of the Earth to completely block out the sun, causing light to appear around the edges of the moon.

Even though it take several minutes for the moon to pass in front of the sun but the total eclipse lasts less than a second.

Annular eclipse coinciding along with longest day of the year will not happen again until 2039.

NASA has mapped the trajectory of the annular solar eclipse, which shows omits path pass over Democratic Republic of Congo, South Sudan, Ethiopia,Eritrea,Yemen,Oman,Pakistan,India, China, Taiwan and Guam.

The eclipse will not visible for people in the Southern Hemisphere,nor in more northerly latitudes like UK.
