Video: The coronary eclipse recommended in Australia

Some regions of the world, including Australia have the opportunity to observe "fire rings", also called coronary solar eclipse.

In Australia, the eclipse began in Tennant Creek cities, Alice Springs and Northern Territory, in the north-west of Australia on May 10. At the time of the solar eclipse, 90% of the solar disk will be obscured by the moon, then the sun will have a ring image.

Vietnam does not observe coronary solar eclipses, only a few other countries can see the phenomenon is Australia, some island countries in the Pacific, and some countries in Southeast Asia.

The coronary solar eclipse occurs every year when the earth is at the closest position to the sun and the moon in the farthest position from the globe.
