where you can observe the “ring of fire”
An annular solar eclipse will take place in October

On October 2, residents of the Southern Hemisphere will be able to see an impressive astronomical phenomenon – an annular solar eclipse, also known as the “ring of fire”. It will not be visible in Ukraine and Europe.
About this writes Space.
The eclipse broadcast will be available for viewing at link.
How an annular solar eclipse occurs
During this eclipse, the Moon does not completely cover the Sun, so a bright rim appears around it. This phenomenon occurs because the Moon is at a greater distance from the Earth during an eclipse, so its size appears smaller than the Sun.
When to observe
The eclipse will begin at dawn, when the Sun will just rise above the horizon. The most interesting moment – the peak of the eclipse – will fall in the middle of the day. This phenomenon will end closer to sunset.
How the speed of the moon’s shadow affects observations
The speed of movement of the shadow of the Moon on the surface of the Earth will differ significantly depending on the place of observation. For example, at the beginning of the path, the shadow of the Moon will be moving at a speed of about 8.55 million km/h in the central Pacific Ocean, south of Hawaii.
However, in other regions the speed will be significantly reduced. At its slowest, the shadow will move at a speed of 2,057 km/h – about the speed of a jet fighter – at a point northwest of Easter Island. In this place, the “ring of fire” will be visible for the longest time – 7 minutes and 25 seconds.
This is due to the fact that at the moment when the eclipse will be most visible, the Sun will be almost at the zenith, and the distance between the Earth and the Moon will be the smallest. The shadow of the Moon will move almost perpendicular to the surface of the planet, which will reduce its apparent speed and increase the duration of observation of the “ring of fire”.
Earlier we told that in a few weeks the scientists launch a spaceship Proba-3, whose two satellites will simulate a total solar eclipse. So scientists are trying to understand solar failures in terrestrial technologies during this phenomenon.
