A total annular solar eclipse will take place on June 21, Sunday, which will be visible completely only from certain places of the country.

An annular solar eclipse is a solar eclipse when the moon is at the farthest point while passing between the sun and the earth.

During this phenomenon, the moon blocks the sun like a smaller disk, and hence the sun looks like a ring of fire.

Scientists say that the path of the eclipse will start near Gharsana in Rajasthan around 10.12 am and the phase of the annularity would start around 11.49 am.

After about a minute, it will dissipate over the sky of that place.

The event will be visible partially in Assam and around 88 per cent of the sun will remain visible.

The eclipse in Assam will start at 10.51 am at Srirampur and end at Jagun in Tinsukia district at 2.23 pm.

The eclipse will start at 10:57 am in Guwahati and will end at 2:24 pm, reaching the maximum coverage of 80.07 per cent at 12:45 pm.

The Assam Science Society and the Science and Bijnan Prasar have jointly undertaken a special programme for viewing this solar eclipse.

For the purpose, the Science Society has trained up 200 resource persons under the supervision of Bijnan Prasar.

The Science Society has urged the people to not view the eclipse directly even with the help of binoculars and telescopes.

"The eclipse should be viewed using safe solar filters, or by creating images of the event on walls or screens," a statement from the Science Society said.
