Solar eclipse 2020: How and when to watch the ring eclipse of June

Solar Eclipse 2020: See the ring eclipse of June on Sunday

“Ring eclipses are similar to total eclipses in that the moon, the Earth and the sun They are aligned so that the moon moves just in front of the Sun, as seen from Earth, “said Alex Young, deputy director of science at the Department of Solar Science at NASA’s Goddard Space Flight Center.

“But a total eclipse does not happen, that is, the moon does not completely rule out the visible disk of the sun because the moon is farther away and so its apparent size in the sky is [slightly] less than the sun. This means that a tiny ring finger on the solar disk is visible around the moon. “

Solar eclipses occur about two weeks before or after a lunar eclipse, Young said. There was a lunar eclipse on June 5 and the next will take place on July 5.

The ring eclipse will begin at 12:47 p.m. ET (4:47 UTC) on June 21 and will cross a bony path that begins at sunrise in Africa and eventually moves to China before ending at sunset over the Pacific Ocean. It will peak at 2:40 a.m. ET (6:40 UTC) and will end at about 4:32 a.m. ET (8:32 UTC).

The partial eclipse will begin at 11:45 p.m. ET (3:45 UTC) on June 20 and ends at 5:34 a.m. ET (9:34 UTC) on June 21st.

It will be visible over Central Africa, the southern Arabian Peninsula, Pakistan, North India and South Central China, Young said. Additional eclipses will be observed in most countries in Asia, Africa, Southern and Eastern Europe, northern Australia and in parts of the Pacific and Indian Oceans, he added.

And of course, the weather allows it, so hopefully the skies will be clear.

The entire eclipse will last about 3.75 hours, but the duration as it passes over individual sites will be equal to about a minute and a half. During peak, this will decrease to just over 30 seconds.

How to watch

Although this is not a total solar eclipse, you need to monitor the eclipse using security measures.

“Because the sun is so incredibly bright, it’s still too bright to look at with unprotected eyes,” Young said. “You need secure sunglasses or special filters for use with telescopes or binoculars.”

Any look at the brightness of the sun is not only unpleasant – it is dangerous. Looking directly at the strong brightness of the sun can cause damage to the retina, the light-sensitive part of the eye. Even the smallest exposure can cause blurred vision or temporary blindness. The problem is that you will not know if it is temporary in the beginning.

Whether you use cardboard eclipse glasses or a handheld card with a single rectangular view, the most important feature is the filter. Make sure the sunglasses meet the ISO 12312-2 international safety standard. Eclipse glasses can be worn over regular glasses.

To check for safety, the only thing you can see through a secure solar filter is the sun itself. If you look inside and the sun is very bright, out of focus or surrounded by a dark fog or if you can see things like ordinary house lights, the glasses are not safe.

If you’re tempted to reuse three-year-old or older sunglasses, they were made before the international safety standard came into effect and come with a warning that says you can’t look at them for more than three minutes at a time. These must be rejected, according to the American Astronomical Society.

First security

If you plan to watch the eclipse via camera, telescope or binoculars, buy a solar filter to place it on the edge of the lens. But don’t wear sunglasses looking at any of them. Concentrated light will pass directly through the filters and will injure your eyes.

Here are some safety tips to keep in mind, according to the American Astronomical Society:

  • Always check your solar filter before use. if it is scratched, punctured, torn or otherwise damaged, discard it. Read and follow the instructions printed or packaged with the filter.
  • Always supervise children using solar filters.
  • If you wear regular glasses, keep them on. Put the eclipse glasses on them or keep your portable viewer in front of them.
  • Stand still and cover your eyes with sunglasses or sunglasses before looking at the bright sun. After looking at the sun, turn it over and remove your filter. do not remove it while looking at the sun.
  • Do not look at the sun that has not closed or is partially shut down via an unfiltered camera, telescope, binoculars or other optical device.
  • Similarly, do not look at the sun through a camera, telescope, binoculars or any other optical device when using smeared glasses or a portable solar panel. Condensed sunlight can damage the filter and enter your eyes, causing serious injury.
  • Seek advice from an astronomer before using a solar filter with a camera, telescope, binoculars or any other optical device. Note that the solar filters must be attached to the front of each telescope, binoculars, camera lens or other optics.
