Solar Eclipse June 2020

Solar Eclipse June 2020


As we know that on 21st June 2020 there would be a Solar Eclipse and we all are going to observe it. So it would be better to know all about solar eclipse before observing 21st June Solar Eclipse. Here is all about Solar Eclipse.

What is a solar eclipse?

Sometimes the Moon lines up directly in between Earth and the Sun during its revolution around the earth and casts its shadow on a part of earth surface. Particularly from those parts of earth surface the sun is not visible. This phenomenon is widely known as solar eclipse.

Solar eclipse happens during day time. As moon blocks maximum sun rays the day time becomes dark as night. It lasts for few minutes only. It happens in every 18 months.

According to the casting of shadow solar eclipse can be of 3 types:

  1. Total solar eclipse: When the Moon completely shades the Sun as seen from some particular part of the Earth. It may be perceived as partial eclipse from the area other than that.

  1. Partial solar eclipse: When the moon only partially covers the sun.

  1. Annular solar eclipse: When the moon appears smaller than the sun and passes centrally across the sun, at some point of time sun looks like a bright ring or annulus of sunlight. This bright light remains visible throughout the eclipse.

NOTE: Although there is a rare type of solar eclipse which changes its appearance as Moons shadow moves across the Earth. This is widely known as Hybrid Eclipse.

How to Watch Solar Eclipse?


According to NASA one can observe Solar Eclipse directly with naked eyes only during a total eclipse when the face of the sun is totally covered by Moon (which is very rare). Other than this in general watching a solar eclipse directly is totally unsafe. It may cause eye damage which can lead to blindness.


Here is Mindcard’s lineation of Do’s and Don’ts of observing Solar Eclipse safely:

  • Do not look at the Sun directly with barely eyes during the eclipse.
  • Do not use ordinary sunglasses, even very dark glasses X-ray films or photographic filters and home-made filters as it is unsafe for eyes because of high density radiation.
  • The safest way to view eclipse is to use Solar Filters or Solar Eclipse glasses.

  • You can use home-made pin hole projector to observe projections of Eclipse.
  • First of all, check the filter/glasses whether it is scratched, toned or damaged or not. If it is then it would be better to not use that.
  • Follow the instructions given with the filter before using it.
  • Do not look at the sun until wearing the glass. First of all, put the glass then look at the Sun.
  • Do dot observe solar eclipse with unfiltered Telescope, binoculars or other unfiltered optical devices.
  • Use Solar Filters with Camera, telescope, binoculars or other optical device to view Eclipse. And it would be better to take advice from experts before using it.
  • While using the solar eclipse glass do not look at the sun through Telescope, binoculars or camera because concentrate rays could damage the filter and may cause serious eye damage.
  • When observation is complete do not remove the glass while keeping the eye towards Sun. It may harm eyes.
  • Take care of children while watching the eclipse.



Science behind solar eclipse :

We all know that we all know that moon revolves around the earth in and fixed elliptical orbit and also Earth revolves around Sun in an elliptical orbit. Due course of revolution when Sun moon and earth aligne at the same line respectively or in other words when moon comes between sun and earth and solar eclipse occurs. During solar eclipse cast a shadow on to the earth.

—- the orbit of the earth around the sun is elliptical, the moon’s orbit around the earth is also elliptical but it is tilted by 15.5 degree as a result the moon wonders above or below the the elliptical path of earth as a result of its orbital inclination. In every New moon the moon appears to pass either above or below the sun and the shadow gradually passes over the Earth accordingly. If the moon revolves in the same orbital plane in which Earth revolves the sun an eclipse would happen every month but it does not occurs so because of tilting.

—– when the moon wonders above and below the elliptical path of earth sometime it crosses the path i.e when the moon reaches the point in its orbit where it crosses earth’s orbit called ‘Node’, an eclipse moon crosses the earth’s orbital plane only twice a year called ‘Eclipse season’.

An ‘ascending node’ is the point where moon crosses the elliptic from South to North. Similarly an ‘descending node’ is for vice versa.

——Eclipse season occurs few weeks earlier each year that is a previous year because the notes are not stationary at all, but they moves continuously westwards or regress along the ecliptic keeping the moon’s inclination unchanged. The complete regression of node takes place in 18.6 years called ‘complete nodal cycle’. If the nodal cycle does not occur or the node remain fixed eclipse season will remain same each year .


During solar eclipse there occurs three types of shadows which are :

  1. Umbra
  2. Penumbra
  3.  Antumbra


  1. Umbra :

The umbra is the innermost and the darkest part of the shadow where the light source or sun becomes completely blocked by the moon. An observer standing at the umbral point on earth will see total eclipse. The umbrella of a round body hindering round light source forms a right circular cone as a result to a  viewer at cone’s apex the two bodies will seem to be of equal size.

  1. Penumbra :

It is the shadow region in which only a part of sun is hindered by moon. An observer at penumbra region experiences partial eclipse.

  1. Antumbra :

It is a shadow region from which the moon appears entirely within the sun’s circumference. An observer in this antumbral region on earth will experience annular eclipse.


—–because the moon is just not enough to cover the sun total eclipse is not possible as a result a ring of light for high energy radiation of sun gets emitted at the peripheral portion of eclipsed sun for over the outer surface of the moon called ‘corona’.


—— the partial phase of eclipse begins when the edge of moon first shows up within sun as a slight  notch. For next few hours the notch gross gradually until the sun looks like a shiny crescent by this time at becomes noticeably darker. In the final moment the narrowing are suddenly breaks into two string of dots, this effect is called ‘ Baily’s Beads’ .

—— the magnitude of an eclipse is the ratio of the apparent size of the moon to the apparent size of the Sun during eclipse. An eclipse when moon is closer to earth, it will be a  total eclipse because the moon will appear to be large enough to cover the the appearing sun in the sky. A total eclipse has a magnitude greater than or equals to 1.0. conversely when an eclipse in which moon is away from Sun, it will be a annular eclipse because moon will appear to be slightly smaller than the sun. The magnitude of an annular eclipse is less than 1. A hybrid eclipse occurs when the magnitude of an eclipse becomes less or greater than 1.0.


Note – the solar eclipse of 21st june 2020 is an  annular eclipse. A small moon over the bright Sun-Disk will appear in the sky with radiating ring of light at the outer circumference.



Why high tide and low tide occurs during solar eclipse??

As during solar eclipse, we all know that Earth moon and sun get aligned in the same axis. Due to this particular alignment the moon comes just before the sun and a man standing on the earth perceives the sun as a ring.

  • Normally when the moon revolves around Earth due to gravitational force of the moon pulling of the water of the sea towards the moon due to which high tide occurs in the part of the earth which is closest to the moon. And low tide occurs in the part of earth which is farthest away from the moon. But this high tide and low tide is not much significant and occurs daily.

  • But during the solar eclipse the moon Earth and the sun get aligned in the same axis. Due to which the gravitational force becomes maximum along the direction of gravitational force of moon. This is because of combined force of moon and sun acting over the Earth. For this reason, there is pulling of the sea water result in high tide which is significant. High tide occurs in the portion of Earth which is nearest to the moon and vice versa for low tide.

Myths Vs Facts:

  1. A lunar eclipse is when the demon god — Rahu — holds the Sun and the Moon by the mouth. And since, he’s a ‘demon’ god, the celestial event emits a lot of negative energy.

-This is just a belief of religious Hindu people, as it was described as an ancient legend in Hindu mythology. But scientist already proved the real reason behind solar and lunar eclipse as it is based on the different alignment between the sun, the moon and the earth.


  1. One should take bath after lunar eclipse ends and must be with the clothes on.

-Scientist claims that emission of strong UV rays takes place during lunar eclipse and water attracts those emission that can cause problems to our skin and also some microbiologist claims that during eclipse as lacks of sunlight the bacteria in water can go hyperactive mode.

  1. you should not have sex.

-It is a myth and there is no proof to support this myth, and scientist also claims that having sex during eclipse won’t cause any harm not even it can affect your sleeping pattern.

  1. Avoid eating food during eclipse.

-Scientist in Kerala claims that it is safe to eat and drink during solar eclipse because during eclipse the brilliant corona emits electromagnetic radiations only. And, another group of scientists also claims that is isn’t healthy to eat during lunar eclipse because it emits UV rays which impact cooked food prepared with water as water attracts further emission and turns the food as poison.

  1. You should not sleep during solar eclipse.

– Sleeping during eclipse doesn’t cause any harm but as eclipse causes daytime darkness that can affect the sleep pattern of a human.

  1. you should not be sitting on an animal.

-There are no particular facts about this myth the only things animals act strange during an eclipse.
