NASA officials say that some parts of Indonesia will get to have a glimpse of this rare total solar eclipse, which will last for more than a minute. Other regions in Southeast Asia will be able to view a partial solar eclipse, including Thailand, Malaysia, Singapore, Philippines, Micronesia, Australia and Hawaii where most of India and Nepal will also be able to see a partially eclipsed sunrise.

Those who are interested to see this incredible sky event should use proper gear such as a solar filtered telescope, dark eclipse glasses or even a pinhole projector.

The moon will directly pass between the sun and Earth which is also a rare event that can only happen only once or twice in a year due to the fact that the sun and the moon do not share the same plane when it comes to their orbits. It is expected that the moon will block the sun's shining face that can reveal a faint layer of the solar atmosphere which is also known as the corona.

According to Sarah Jaeggli from NASA's Goddard Space Flight Center, when the moon blocks the light shining from the sun's surface at a very precise manner, what can be seen are the roots of the corona which is where the atmosphere and the surface of the sun meets. 

Those who can view this totality should be in the area spanning 8,800 miles however, it is estimated that the widest point is at 97 miles only, who can see the sun's corona as the sun is totally covered by the moon, as people outside this area can observe different degrees of a partial eclipse.

Astronomers also say that the duration of this totality can last from half a minute to over four minutes, depending on the location, but there will be a three hour pass beginning from the western region to the eastern region during the entire eclipse.

A solar eclipse is basically the moon's shadow that is cast upon Earth where the shadow consists of two cones known as umbra and the penumbra. The central penumbra shadow is where the sun is completely blocked by the moon, as anyone who is viewing the umbra can see a total eclipse. Those who can see a partial eclipse are only viewing within the outer cone, penumbra.
