A solar eclipse occurs when the sun, moon and Earth are aligned with the moon in between. A total solar eclipse takes place when the moon completely blocks out the sun's light, and an annular eclipse happens when the moon is farthest from Earth, as the moon seems smaller and doesn't block the entire view of the sun, said NASA.

Experts warned observers not to watch the eclipse with naked eyes or with sunglasses or through telescopes. Eclipse viewing glasses were recommended, and the continuous observation time should be no more than two minutes.

They also warned not to point the lens of cameras or telescopes directly toward the sun, otherwise, the devices could burn out.
