2021 Total Solar Eclipse: How to watch on 4th December
How to watch Total Solar Eclipse?
On Saturday (Dec. 4), the year’s only total solar eclipse will occur, and those living in the far south of the globe may be able to see it. Alternatively, if the Antarctic weather holds, a live stream may be accessible.
Solar eclipses occur when the new moon passes in front of the sun’s face as seen from Earth.
When the moon is close enough in its orbit around Earth to block 100 percent of the solar disc, a total solar eclipse occurs, such as the one that crossed the United States on Aug. 21, 2017. Observers in the limited line of totality will view a 360-degree sunset and the sun’s fiery outer coating, known as ‘the corona’, during the eclipse peak.
Although some partial phases can be seen in Australia, New Zealand, Argentina, and South Africa, the best visibility for this eclipse is from Antarctica and adjacent waters.
After the 2021 eclipse, we’ll have to wait nearly 18 months for the next total solar eclipse, which will occur on April 20, 2023. According to NASA‘s eclipse site, this will pass across a much more populated region, including south and east Asia.
The eclipse, like most solar eclipses, will be brief. From Earth’s perspective, the moon’s shadow is quite small, and we are fortunate that it is sometimes just big enough to cover the full face of the sun.
According to Sky & Telescope, totality will endure only 1 minute and 54 seconds at most; however, this is extremely dependant on where you are standing within the path of totality. The eclipse’s partial phase will last one hour.
The partial solar eclipse starts at 2 a.m. EST (0700 GMT), and the total solar eclipse’s maximum peak is at 2:33 a.m. EST (0733 GMT). According to NASA, the partial eclipse will end around 3:06 a.m. (0806 GMT).
Tips for safe watching
Use special protective eyewear or certified eclipse glasses to safely observe the sun or watch an eclipse. Simple sunglasses, even if they provide UV protection, are insufficient to safeguard your eyes. The safest way to see an eclipse is with a pinhole camera, which you can easily create at home.
Even during near-totality phases, astronomers must employ special sun filters on their equipment. Even with your smartphone, a basic wide-angle shot should suffice if you need to chronicle one of these events with a camera.
During solar eclipses, NASA advises that you exercise extreme caution. “If you’re in the path of a total solar eclipse, you should only remove your solar viewing or eclipse glasses when the moon blocks the sun,” NASA says.
