What time is the solar eclipse 2022 – Duration, Precautions and More

What time is the solar eclipse 2022

The first solar eclipse of the year is going to happen soon. This eclipse will take place on Saturday 30th April. Let’s see what time is the solar eclipse 2022, precautions, & more

 

What is Solar Eclipse?

A solar eclipse occurs when the Earth, moon, and sun are in the same plane and the moon passes between the Earth and the sun, partially or completely covering our nearest star.

Solar eclipses, particularly total eclipses, entice crowds as one of the most dramatic celestial displays; however, no matter how much of the sun is obscured by the moon’s shadow, you should never look at the sun directly.

“During this period, when any of the disks are visible, one must use safety equipment to view the sun,” William Teets, director of Vanderbilt University’s Vanderbilt Dyer Observatory in Nashville, Tennessee, told Live Science via email. This could include wearing sunglasses, using specially filtered telescopes or binoculars, or using a projection system, Teets said.

Solar eclipses are classified into four types: total, annular, partial, and hybrid.

 

What time is the solar eclipse 2022?

In 2022, it will be the first of two partial solar eclipses. The second will be held on October 25, 2022. According to Indian Standard Time, the Surya Grahan will begin at 12:15 a.m. and end at 4:07 a.m. on April 30. (IST).

On October 25, there will be the second and final solar eclipse of the year. In addition, there will be a partial solar eclipse.

How to watch the solar eclipse?

Without protective equipment, do not look directly at any part of the sun, even if it is near totality.

“This tool could be approved solar eclipse glasses (not sunglasses), or a properly filtered telescope or binoculars.”

“Never put on solar eclipse glasses and then try to look through an uncensored telescope or pair of binoculars — the unfiltered illumination will burn right through the glasses and start to burning and blind you as well,” Teets added.

Method of projection

In addition to viewing an eclipse through special glasses or properly filtered telescopes/binoculars, you can also view a solar eclipse through a projection method. To accomplish this, remove the eyepiece from a telescope and project the image onto a sheet of paper behind the telescope. According to Sky & Telescope, you can find the spot with the most focused image by moving the sheet of paper back and forth.

Pinhole camera

According to Sky & Telescope, a pinhole or small opening is used to shape an image of the sun on a screen placed about 3 feet (1 meter) behind the opening. A magnified image of the sun can also be projected onto a white card using binoculars or a small telescope mounted on a tripod. The larger the image can be focused, the farther away from the card. Search for sunspots. Take note of how the sun appears darker around its limb or edge.

This method of solar viewing is safe as long as you remember not to look through the binoculars or telescope while they are pointing toward the sun; in other words, never look directly at the sun when any portion of its blindingly bright surface is visible.

Pinhole mirror: The “pinhole mirror” is a variation on the pinhole theme. Cover a pocket mirror with a quarter-inch hole punched piece of paper. Open a window facing the sun and place the covered mirror on the sunlit sill, reflecting a disc of light onto the far wall inside. The light disc is a representation of the sun’s face.

According to Sky & Telescope, the image will be only 1 inch across for every 9 feet (or 3 centimeters for every 3 meters) away from the mirror. To hold the mirror in place, modelling clay works well. Experiment with different-sized paper holes.

A large hole, once again, makes the image bright but fuzzy, while a small one makes it dim but sharp. Dim the lights as much as possible. Make sure to test this out beforehand to ensure that the mirror’s optical quality is sufficient to project a clean, round image. Of course, no one should look at the sun in the mirror.

Look at the shadows cast by leafy trees during the partial phases if you’re near them. What do you notice? Is it worth taking a picture of? Countless partially eclipsed suns will be projected through pinhole gaps between the leaves. Diffraction, a property of light, is responsible for this.

According to Vince Huegele, an optical physicist at NASA Marshall Space Flight Center, light rays do not shoot straight through the gaps or pinholes, but instead, bend around the edge. This wave effect produces a ring pattern that resembles a bull’s eye.

Aluminized Mylar filters

Aluminized Mylar filters are suitable for unaided visual solar observations. Some astronomy stores stock Mylar filter material that is specifically designed for solar observing. Shade 14 arc-glass welder’s is also acceptable and can be purchased for a few dollars at welding supply shops. Of course, testing your filters and/or observing techniques before the eclipse is always a good idea.

 

Cautions

1. Do not look at the sun directly.

2. Do not view a Solar Eclipse or Surya Grahan with ordinary sunglasses or home-made filters.

3. To view the eclipse, only use special-purpose solar filters, such as eclipse glasses or handheld solar viewers.

4. Carefully read and follow the instructions on the solar filters.

5. It is not advisable to look directly at the sun with a camera, binoculars, telescope, etc. during any stage of the eclipse. Solar rays may be concentrated at one point through these devices, causing serious eye injuries (s).

6. Inspect the solar filter thoroughly for any damages or scratches before using it to view the eclipse. If there is any, throw away the solar filter.

7. You can remove your solar filter during an eclipse only to view the path of totality, as the moon will cover the sun during this time. As the sun begins to reappear, one must immediately reapply the solar filter.

8. If you normally wear glasses, keep them on during an eclipse with a solar filter over them.

9. Keep your headlights on while driving during a solar eclipse or Surya Grahan. Also, keep an eye out for distracted drivers, as sudden darkness in some areas during the eclipse’s maximum phase may result in an accident.

10. Slow down when driving during an eclipse.

11. Do not look at the sun’s reflection on water.

12. The pinhole imaging technique can be used to view the eclipse’s reflection on your home’s wall.

Sunglasses, old color film negatives, black-and-white film with no silver, photographic neutral-density filters, and polarizing filters are all prohibited. These materials transmit very little visible light, but they transmit an unacceptably high level of near-infrared radiation, which can burn your retinas. The fact that the sun appears dim or that you do not feel any discomfort when looking at it through these types of filters does not mean that your eyes are safe.

 

Equipment to see Solar Eclipse

Sunspots

Sunspots are dark patches of relatively cool material on the sun’s surface. Teets predict that they will appear as black spots on the sun’s disc. These spots can be found alone or in groups of several. These spots are usually too small to see through solar eclipse glasses, so you’ll need a properly filtered telescope to see them.

prominences

If you’re watching the eclipse with a “hydrogen-alpha solar telescope,” you might see more than just sunspots. With this equipment, you should be able to see prominences and the chromosphere, the second of the sun’s three layers of atmosphere.

“Prominences are clouds of material lofted up from the sun, and they sometimes resemble flames on the sun’s edge,” Teets explained. “If they are present across the sun’s disc, they will appear as slightly darkened streaks.”

Chromosphere

Using the same specialised telescope, you could see what appears to be undulating ruby gems dancing around the sun’s outer disc. According to the University Corporation for Atmospheric Research, this is the chromosphere, the sun’s lower atmosphere that is about a million times less dense than Earth’s atmosphere. According to UCAR, the light from this atmospheric layer is drowned out by the much brighter photosphere beneath it on most days.

Corona

There is only one time when you can safely look directly at the sun: during totality when the sun’s disc is completely covered by the moon. The magnificent corona — the outer atmosphere just above the chromosphere — shines forth in all its glory like a halo around the darkened sun — a marvelous fringe of pearly white light — during those few precious seconds or minutes. Teets told Live Science, “It appears as a beautiful white wisp that totally encircles the sun.”

The size, tints, and patterns vary from eclipse to eclipse. It is always faint and delicate, with a sheen reminiscent of a pale aurora borealis. The corona appears as a soft continuous structure at times, and long rays of it shoot out in three or four directions at other times. The corona can also emerge from the disc in the form of filmy petals and streamers. When the sun comes back into view, the corona quickly fades, and you’ll need to protect your eyes once more. You can see corona Solar Eclipse with any Optical devices.
