An annular solar eclipse is a rare occurrence and has been observed from India in the recent past on January 15, 2010, and September 1, 2016, respectively. The most recent solar eclipse occurred last year on December 26. This year the solar eclipse will be on June 21, followed by one on December 14.
According to TimeAndDate, the annular solar eclipse will be first visible on June 21, 2020, around 9.15 AM IST, until around 3.04 PM IST. The eclipse will be visible from parts of Africa, Pakistan, India and China. People residing in these areas will see the characteristic ring of fire, depending on favourable weather conditions at the time.
In case of a total eclipse, the disk of the Sun is fully obscured by the Moon, however, in partial and annular eclipses, only part of the Sun is obscured. June 21 will witness an annular eclipse.
During annular solar eclipses, a ring of fire is formed around the moon’s periphery and it is different from a total eclipse.
A solar eclipse always occurs approximately two weeks before or after a lunar eclipse. In most cases, two eclipses occur simultaneously but a few times there also are three during the same eclipse season. This is the second eclipse this season. The first eclipse of this season was on June 5, 2020, and the other will follow on July 5, 2020, both penumbral.
What is an annular solar eclipse?
A solar eclipse is a celestial event observed when the sun, the moon, and the Earth are in alignment only during a new moon phase. The moon blocks out the sun thereby casting a shadow on Earth’s surface causing a total, partial or annular eclipse.
A total solar eclipse occurs when the sun, moon and Earth are in a direct line, so the moon completely blocks the sun. During a partial solar eclipse, the sun, moon and Earth are not exactly in a perfect line so the moon casts only a small shadow on the Sun’s surface.
An annular solar eclipse is similar to a total solar eclipse as the sun, the moon, and the Earth must be in perfect alignment. According to NASA, an annular solar eclipse happens when the moon is farthest away from Earth which causes the moon to seemingly appear smaller.
As the size of the moon is smaller than that of the sun, during the eclipse, the periphery of the sun appears as a ring around the moon. The ‘ring of fire’ and the dark moon forms the shape of an annulus or the area between two concentric circles.
Another astronomical phenomenon called a transit occurs when one celestial body passes between a larger celestial body and a third one. As Earth is the third planet from the Sun, we can observe transits of both Mercury and Venus.
During any type of eclipse, there are a few dos and don’ts which you must follow:
- People usually prefer staying indoors during the eclipse hours.
- No food items are consumed during this time.
- Add Tulsi leaves in your eatables and water to prevent any ill-effects of the Grahan
- Taking a bath and changing into new clothes is advisable during the eclipse
- Chanting of mantras dedicated to the Sun God is also followed by many households
- Expectant mothers are especially advised to stay indoors and chant the Santana Gopala Mantra
- Any auspicious task is avoided during the eclipse duration in several households.
- An eclipse should not be viewed with one’s naked eye as it can damage the eye.
- Skywatchers are advised to use binoculars, a telescope or an optical camera viewfinder with optimal filters to watch the eclipse. A normal-use binocular or telescope is a strict no-no.
