“But a total eclipse does not occur, ie the moon does not completely block the visible disk of the sun because the moon is farther away and its size that is visible in the sky is [slightly] smaller than the sun. This means that the small ring of the sun disc is visible around the moon. “
A solar eclipse occurs about two weeks before or after a lunar eclipse, Young said. There was a lunar eclipse on 5 June and the next one occurred on 5 July.
The annular eclipse will start at 12.47 ET time (4:47 UTC) on June 21 and cross a thin road that begins at sunrise in Africa and finally moves across to China before ending at sunset in the Pacific Ocean. It will peak at 02:40 ET (6:40 UTC) and end around 4:32 ET (8:32 UTC).
The partial eclipse will begin at 11:45 tonight. ET (3:45 UTC) on June 20 and ending at 5:34 ET (9:34 UTC) on June 21.

This will be seen in central Africa, the southern Arabian Peninsula, Pakistan, North India and South Central China, Young said. Partial eclipses will be seen in much of Asia, Africa, Southern and Eastern Europe, northern Australia and parts of the Pacific and Indian Ocean, he added.
And of course, this allows the weather, so hopefully the sky will be clear.
The entire eclipse will last around 3.75 hours, but the duration when passing through each location will be the same about one and a half minutes. During the peak, it will actually shorten to more than 30 seconds.

How to watch
Even though this is not a total solar eclipse, you still need to watch the eclipse using security measures.
“Because the Sun is extremely bright, it is still too bright to be seen with unprotected eyes,” Young said. “You need safe sun glasses or special filters for use with telescopes or binoculars.”
A glance at the brightness of the sun is not only uncomfortable – it’s dangerous. Looking directly into strong sunlight can cause damage to the retina, the part of the eye that is sensitive to light. Even the smallest amount of exposure can cause blurred vision or temporary blindness. The problem is, you won’t know whether it’s temporary at first.
Whether you use cardboard eclipse glasses or a hand-held card with a single square display, the most important feature is the filter. Make sure your eclipse glasses meet ISO 12312-2 international safety standards. Eclipse glasses can be worn over ordinary glasses.
To test safety, the only thing you can see through a safe solar filter is the sun itself. If you look inside and the sun is too bright, out of focus or surrounded by murky fog, or if you can see things like ordinary household lights, the glasses are not safe.
If you are tempted to reuse eclipse glasses that are three years old or older, they are made before international safety standards apply and a warning appears saying you cannot see through glasses for more than three minutes at a time. This must be discarded, according to the American Astronomical Society.
Safety first
If you plan to watch the eclipse through a camera, telescope or binoculars, buy a sun filter to put on the end of the lens. But don’t wear eclipse glasses when you see all this. Concentrated light will penetrate the filter and cause injury to your eyes.
The following safety tips to keep in mind, according to the American Astronomical Society:
- Always check your sun filter before use; if scratched, punctured, torn or damaged, throw it away. Read and follow the instructions that are printed or packaged with filters.
- Always supervise children using sun filters.
- If you usually wear glasses, keep wearing them. Place your eclipse glasses on it, or hold your handheld viewer in front of it.
- Stay still and cover your eyes with eclipse glasses or sun viewers before looking at the bright sun. After seeing the sun, turn around and remove your filter; do not release when looking at the sun.
- Do not see the sun that is not covered or partially blocked through cameras, telescopes, binoculars or other optical devices that are not filtered.
- Likewise, do not look at the sun through cameras, telescopes, binoculars or other optical devices when using your eclipse glasses or handheld sun viewer; Concentrated sunlight can damage the filter and enter your eyes, causing serious injury.
- Get expert advice from an astronomer before using a solar filter with a camera, telescope, binoculars or other optical device; note that solar filters must be installed on the front of the telescope, binoculars, camera lenses or other optics.
