What is a solar eclipse?
- A solar eclipse occurs when the disk of the Moon passes between the Sun and the Earth, and
- The shadow cast by the Moon temporarily blocks the Sun’s rays from reaching the Earth.
- 3 types of solar eclipses:-
- The partial solar eclipse, wherein the Moon blocks just a part of the Sun;
- The total solar eclipse, where the Sun is covered by the moon completely;
- Lastly, the annual solar eclipse, which will be on display over north India come Sunday.
What is an annular solar eclipse?
- An annular solar eclipse occurs when the apparent size of the Moon is slightly less than that of the Sun,
- Which leaves the outer rim of the latter uncovered, giving the appearance of a “ring of fire”.
- India will witness its “deepest” annular solar eclipse of this century on Sunday,
- With the Sun appearing as a necklace of pearls for around 30 seconds during the maximum phase
- Along a narrow corridor running through Rajasthan, Haryana and Uttarakhand.
- The eclipse will be partial in the rest of the country.
- The partial eclipse will be visible in India from different places at different timings between 9:56 am and 2:28 pm.
Where will solar eclipse appear?
- On June 21, the annular eclipse will first start for the people of Congo in Africa and progress through South Sudan, Ethiopia, Yemen, Oman, Saudi Arabia, the Indian Ocean and Pakistan,
- Before entering India over Rajasthan.
Why Deepest?
- During this eclipse, that ring is expected to be very thin as the Moon will cover up to 98.8% of the solar disc,
- Making it the “deepest” annular eclipse of the century in India, according to experts.
- It is also the first time since 2001 that the solstice coincides with a solar eclipse.
How can the eclipse be viewed?
- The solar eclipse must not be viewed with the naked eye under any circumstances.

- If a filter isn’t available, the best as well as the cheapest way to see the eclipse is to use a plane mirror to project the Sun on a screen or a wall.
