Solar eclipse in the horizon 2020: See June of the annular eclipse on Sunday


“Annular are similar to total eclipses in that the moon, the Earth and the sun are aligned so that the moon moves directly in front of the Sun as seen from Earth, ” said Alex Young, associate director for science in the heliophysics science division NASA Goddard Space Flight Center.

“But a total eclipse does not happen, it is the moon does not completely block the visible disk of the sun, because the moon is farther away, and thus its apparent size in the sky is [slightly] smaller than the sun. This means that a tiny ring of the ring of the sun’s disk is visible around the moon. ”

Eclipses of the sun occur about two weeks before or after an eclipse of the moon, Young said. There was an eclipse of the moon on 5 June, and the next place on the 5th of July.

The annular eclipse will begin at 12:47 pm (EST) (4:47 UTC) on June 21, and the cross a skinny path that begins at sunrise in Africa and, finally, moves through China, before ending at sunset on the Pacific Ocean. It will be at its maximum at 2:40 pm ET (6:40 UTC) and end around 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 end at 5:34 pm ET (9:34 UTC) on June 21.

It will be visible over central Africa, south of the Arabian Peninsula, Pakistan, India, North and South Central China, Young said. A partial eclipse will be visible in most of Asia, Africa, the South and the East of Europe, northern Australia and the Pacific regions and the Indian ocean, he added.

And of course, this is weather permitting, so I hope that the sky will be clear.

The totality of the eclipse will last about 3.75 hours, but the length of time that it passes above each location will be equal to about a minute and a half. During the peak period, which will shorten to a little over 30 seconds.

If you want to watch the annular eclipse, but live outside of the display area, The Telescope Project will share a live view.

How to watch

Although this is not a total eclipse of the sun, you still need to look at the eclipse with the help of security measures.

“Because the Sun is so incredibly bright, it is still too bright to look at with unprotected eyes,” Young says. “You need solar viewing glasses or special filters for use with telescopes or binoculars. ”

No preview of the light of the sun is not only uncomfortable — it’s dangerous. Looking directly at the powerful brightness of the sun can cause damage to the retina, the light sensitive part of the eye. Even the smallest amount of exposure can cause blurred vision or temporary blindness. The problem is, you won’t know if it is temporary at first.

If you use cardboard eclipse glasses or a pocket-sized computer board with a single rectangular view, the most important feature is the filter. Make sure that your eclipse glasses meets the standard ISO 12312-2 international safety standard. Eclipse glasses can be worn over glasses.

To test the safety, the only thing that you can see through a safe solar filter is the sun itself. If you look through and the sun is too bright, out of focus, or surrounded by a cloudy haze, or if you can see things like simple household lights, the glasses are not safe.

If you’re tempted to re-use eclipse glasses that are three years or more, they have been made before that the international standard of security was in place and to come with a warning that says you can’t look through them for more than three minutes at a time. These should be discarded, according to the American Astronomical Society.

Safety first

If you are planning to watch the eclipse through a camera, a telescope or binoculars, buy a solar filter to place on the end of the lens. But don’t wear eclipse glasses while looking through one of these. The concentrated light will go right through the filters and cause injury to your eyes.

Here are some safety tips to remember, according to the American Astronomical Society:

  • Always inspect your solar filter before use; if it is scratched, punctured, torn, or damaged, discard it. Read and follow all instructions printed on or packaged with the filter.
  • Always supervise children using solar filters.
  • If you usually wear glasses, keep them on. Put on your eclipse glasses, or keep your computer to pocket viewer in front of them.
  • Stand still and cover your eyes with your eclipse glasses or solar viewer before looking at the sun. After you have looked at the sun, turn away and remove your filter, do not remove it while looking at the sun.
  • Do not look at the uneclipsed or partially eclipsed sun not filtered through a camera, telescope, binoculars, or other optical device.
  • Likewise, do not look at the sun through a camera, a telescope, binoculars or any other optical device when using your eclipse glasses or solar pocket viewer; the concentration of the solar rays, could damage the filter and enter your eyes, causing serious injury.
  • Seek expert 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 any telescope, binoculars, camera lens or other optical.
