Solar Eclipse annular 2020: how to watch a celestial event rarely live this week


A rare type of solar eclipse is taking place this week across large parts of the world, while the Sun, Moon and Earth line up.

The solar eclipse annular and total occurs when the moon is too far away in its orbit of the earth to completely block the sun, causing the appearance of light around the edges of the moon.

The name of a ring is derived from the latin word for ring and the effect it creates has been designated by astronomers as a “ring of fire”.

It takes several minutes for the moon to pass in front of the sun but total solar eclipse lasts less than a second.

The path of the solar eclipse annular crosspiece on Sunday, June 21 in Africa, central Asia and South-East Asia.

Nasa has made a map of its trajectory, showing where the phase annular eclipse will be visible, if time allows.

Millions more will be able to attend a partial solar eclipse, but unfortunately for observers of the sky in the United Kingdom and the United States, it will not be visible.

“You can be hundreds of kilometres from the theoretical point of greatest duration [magenta line on the map] and always have a annularity lasts a fraction of a second to the maximum possible, ” said Nasa on its website.

“It is much more important to watch the weather forecast a day or two before the eclipse and choose a location with the best opportunity to have a sky without clouds during the eclipse.

“The weather is the key to the success of the visualization of eclipses – better to see an eclipse shorter of the clear sky an eclipse longer under the clouds. ”

A live stream of the eclipse will be broadcast by, enabling anyone to watch, regardless of where it is located in the world.

A second solar eclipse is expected to take place on December 14 of this year, through the South America, the Atlantic and Pacific oceans, Antarctica, and Africa.

This will be a total solar eclipse, which means that the moon completely block the sun and will cast a shadow on the Earth.
