On 26 December, there will be an annular solar eclipse that will take place and it will be visible from Saudi Arabia, southern India and parts of Indonesia. People in Europe, other parts of Asia and Australia will see a partial solar eclipse.
An annular solar eclipse takes place when the moon covers the Sun's centre, leaving the Sun's visible outer edges to form a "ring of fire” or annulus around the moon. The name “annular” comes from the Latin word for a ring — “annulus.”
Since the moon's shadow is not big enough to engulf the entire Earth, the shadow falls only in certain areas. This area constantly changes because the moon and Earth are always on the move. Solar eclipses are only visible from within the area where the shadow falls, and the closer you are to the centre of the shadow's path, the bigger the eclipse looks.
This eclipse will be the third and the final solar eclipse for this year and the next eclipse that will take place will be a lunar eclipse, on 10 January 2020.
The partial eclipse will begin by 8 am IST and will last till 11.30 am IST. The annularity, on the west coast, will begin at 9.24 am IST and will begin on the east coast, a few minutes later at 9.31 am IST. The annularity ends at 9:27 am on the west coast and 9:35 am on the east coast.
Where can you view it?
According to Business Insider, if you live in the states of Tamil Nadu and Kerala you will be able to watch the annular solar eclipse. In Tamil Nadu, you can see the annularity for three minutes, 11 seconds in Tiruppur and for three minutes and 15 seconds in Ammapattinam on the east coast.
The annularity will last for three minutes in Ooty and since it is a hill station with an altitude of 2,200 metres, this location will lead to the best view of the solar eclipse without being obstructed by the clouds. According to The Hindu, Kerala's Cheruvathur will also be one of the best places to witness the eclipse.
How to view a solar eclipse
Watching a solar eclipse can be harmful to the eyes without some safety equipment. A major misconception is that you can use sunglasses to look at the sun during an eclipse, however, that is not true.
Your protective eyewear needs to have a sun filter or be a specially-made pair of eclipse glasses. The UV radiation can burn the retinas causing serious damage and even lead to blindness. Keep your back turned to the sun. Seeing the eclipse on an optical instrument through a screen – your mobile phones, televisions or camera screens are perfectly okay.
Binoculars, camera viewfinders, and telescopes, however, can end up causing instant and permanent blindness.
The trusty, old-school way to watch an eclipse safely is crafting a DIY solar eclipse viewer, like this one made out of a cereal box:
