Surya Grahan 2019, Solar Eclipse 2019: Scientists say that the only safe way to look directly at the uneclipsed or partially- eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers.
Some parts of India and the world will witness partial solar eclipse on December 26, Thursday. This is an “annular” solar eclipse, also known as “ring of fire”. The annular solar eclipse occurs when the moon covers the sun from its center, leaving its outer edges visible. So this year, the Moon will cover Sun from the center, while the edges will form what’s known as “ring of fire”. According to timeanddate.com, the first location to see the beginning of partial eclipse is 7:59 am IST. The first location to see the beginning of full eclipse is 9:04 am IST. The maximum eclipse would occur at 10:47 am IST. The last location to see the end of full eclipse is 12:30 pm IST and last location to see the end of partial eclipse is at 1:35 pm IST. It will initially be visible as a partial eclipse and emerge in Riyadh and Saudi Arabia first. The partial eclipse will also be visible in various Indian locations like Mumbai, Bengaluru and New Delhi. It will also be visible in Doha, Dubai, Kuwait City, Karachi, Kuala Lumpur, Jakarta, General Santos, Davao, and Saipan.
Surya Grahan: Myths, Dos and Don’ts Of Watching Solar Eclipse:
1. NASA advises that it is dangerous to see solar eclipses through naked eyes and it can damage one’s eyes. So don’t look at the Sun directly. Looking at the Sun, even for a few seconds, can lead to permanent damage to the retina of the eye, it says.
2. Don’t look at the Sun even while using any kind of optical aid like binoculars, a telescope, or an optical camera viewfinder as it can be extremely hazardous and can cause irreversible eye damage within a fraction of a second.
3. Don’t try to use sunglasses, smoked glass, or some other home-made substitute. They’re not safe to use during partial solar eclipse or surya grahan.
4. Use eye protection during surya grahan like a special eclipse glasses should be used to witness the solar eclipse. Always use special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers to watch the solar eclipse, say scientists.
5. Scientists say that the only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers. NASA suggests that when using or buying the eclipse glasses or hand-held solar viewers, they should be verified to be compliant with the ISO 12312-2 international safety standard for such products.
6. Always inspect solar filter before use. If scratched or damaged, discard it. Read and follow any instructions printed on or packaged with the filter, suggests NASA.
