Total Solar Eclipse is not visible in India but through online NASA TV we will be able to see or we can watch a live stream of the total solar eclipse on AccuWeather.com. Bloomberg report says that the solar eclipse will begin off the coast of New Zealand with Chile and Argentina directly in the path of totality.

According to accuWeather.com in South America  the expected time of the eclipse to occur are:

Surya Grahan or Total Solar Eclipse 2019: 9 Interesting Facts

What is Solar Eclipse?

Solar Eclipse occurs when the Moon comes in between the Sun and the Earth. As a result, the visible disc of the Sun is partially or fully covered by the Moon. The shadow of Moon travels over the surface of the Earth and blocks out the Sun's light as seen from the Earth. It is a celestial phenomenon that does not occur very often.

The Moon orbits the Earth at an angle approximately 5 degrees relative to the Earth-Sun plane then the Moon crosses the orbital plane of the Earth only twice a year. These times are known as eclipse seasons because at this time only eclipses occur. For the formation of an eclipse, it is necessary that Moon must be in the correct phase and that too during an eclipse season. Let us tell you that, for Solar Eclipse, it must be a New Moon. This condition makes solar eclipse relatively rare to occur.

However, viewing the Sun during partial and annular eclipses requires special type of eye protection or indirect viewing methods.

When did Total Solar Eclipse occur?
A Total Solar Eclipse occurs when two events at the same time happen.

The first event is a New Moon. At this phase: the Moon occurs when the Sun is almost directly behind the Moon and we see only a silver of the Sun's light reflected by the Moon. During this time the Moon and the Sun appear close together.

The Second event: It is necessary that the Moon must be in the right position, directly in the line of sight between the Earth and the Sun. These two events occur at the same time about once every year and a half.

The shadow of the Moon has two parts: a central region known as umbra and another region is known as penumbra. Depending upon which part of the shadow passes you, three types of solar eclipses visible to you namely:

- Total Solar Eclipse: In this, the entire central portion of the Sun is blocked out.
- Partial Solar Eclipse: Only a part of the Sun's surface is blocked out.
- Annular Solar Eclipse: Only a small, ring like silver of light is seen from the Sun's disc.

Let us explain the phenomena:

If the umbra region of the Moon passes you then the entire central position of the Sun will be blocked out and you will be able to see Total Solar Eclipse. As a result sky becomes darken as if night time appears. At the time of Total Solar Eclipse, the Sun's outer atmosphere corona is visible. In fact it is said that this is the only time when corona of the Sun is visible.
If the penumbra passes over you then only a part of the Sun's surface is blocked out and Partial Solar Eclipse occurs. At this time sky may dim slightly depending on how much of the Sun's disc is covered.

In some cases, the moon is far enough that is away from its orbit such that the umbra never reaches the Earth at all. And at this time, Annular Solar Eclipse occurs. A small, ring-like silver of light is seen from the Sun's disc.

So, now you may have understood the phenomena of Total Solar Eclipse, its types and how it occurs?
