How and when to watch the June solar eclipse

Annular eclipses are similar to total eclipses in that 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 Center.
But a total eclipse does not happen, that is the moon does not completely block out the visible disk of the sun because the moon is farther away and so its apparent size in the sky is [slightly] smaller than the sun. This means that a tiny ring of annulus of the solar disk is visible around the moon.

Where to see it!
The annular eclipse will begin at 12:47 a.m. ET (4:47 UTC) on June 21 and cross a skinny path that starts at sunrise in Africa and eventually moves across to China before ending at sunset over the Pacific Ocean. It will peak at 2:40 a.m. ET (6:40 UTC) and end around 4:32 a.m. ET (8:32 UTC).
The partial eclipse will begin at 11:45 p.m. ET (3:45 UTC) on June 20 and end at 5:34 a.m. ET (9:34 UTC) on June 21.

It will be visible over central Africa, the southern Arabian Peninsula, Pakistan, Northern India and South Central China. A partial eclipse will be seen over most of Asia, Africa, South and East Europe, northern Australia and parts of the Pacific and Indian Oceans.The entire eclipse will last about 3.75 hours, but the duration as it passes over individual locations will equal to around a minute and a half. During the peak, that will actually shorten to just over 30 seconds.

How to watch!
You need to watch the solar eclipse using safety measures.
Because the Sun is so incredibly bright, it is still too bright to look at with unprotected eyes.You need safe solar viewing glasses or special filters for use with telescopes or binoculars.
