New Delhi: When it's 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. The world is about to witness its second solar eclipse of 2020 on June 21. This one is going to be an annular eclipse. 

From India, annular phase will be visible in the morning from some places within a narrow corridor of the northern part of the country (parts of Rajasthan, Haryana and Uttarakhand) and it will be seen as partial solar eclipse from the rest part of the country.

The Annular solar eclipse forms a ring of fire but is different from a total eclipse. It will be visible in parts of Africa including the Central African Republic, Congo, Ethiopia, Pakistan, India, and China.

Take Note: The eclipsed Sun should not be viewed with the naked eye, even for a very short time. It will cause permanent damage of the eyes leading to blindness even when the moon covers most portion of the Sun. The safe technique to observe the solar eclipse is either by using a proper filter like aluminized Mylar, black polymer, welding glass of shade number 14 or by making a projection of Sun’s image on a whiteboard by telescope.
