Partial Lunar Eclipse 2019


What is Partial Lunar Eclipse?

It is an astronomical phenomena that happen when the position of the Sun, the Earth and the Moon are not on a straight line so it is not the whole body of Moon covered by the earth shadow, it is only partially covered.

How does it happen?

When the Earth moves between the Sun and Moon and the three of them do not form a straight line,a small part of the Moon covered by the darkest,central  part of the Earth’ shadow called umbra.The other side of the Moon is covered by the penumbra,the outer side of Earth shadow.Eclipse started when the Moon pass through the Earth’ shadow in sequence.Initially, it will enter the penumbra which is not really noticeable and then it enter the umbra where we can see the dark shadow of the Earth cover  the Moon surface.At the final stage,the Moon will enter the penumbra back and move out of the Earth’s shadow.

For this to occur the Moon must be in Full Moon phase and the Sun ,earth and Moon must be not precisely aligned. However partial lunar eclipse do not occur every month,every Full Moon.This is because of the inclination of the Moon’s orbital plane to the Earth’s oribital plane inclined at 5°. 

How and where to see?

It do not require any special equipment to see it,just your eyes and a clear skies. What you need is the exact time and date when it can be seen from your place.It can be seen anywhere across the night side of the Earth.
