Definition of Partial Solar Eclipse          

It is a solar eclipse in which the Moon partially cover the Sun’s disk. When it happen  the Sun, the Moon and the Earth were not align in perfectly straight line. Since major part of Malaysia witness partial solar eclipse,hence the features that visible during annular solar eclipses such as the ring of fire are invisible for people living outside of the totality path.

Occurrence of Solar Eclipse

Solar eclipse happen 2-5 times a year, during new moon phase. However,solar eclipses do  not occurs in every new moon because of the inclination of Moon’s orbit  to the Earth’s orbit at  5°. Solar eclipse will occur when both orbit meet at a point called lunar nodes. For both total and annular solar eclipses can also be seen as partial solar eclipse for anyone who live within the moon’s penumbra shadow.
