The shadow of the earth cast by the sunlight will have one darker shadow or umbra and a lighter shadow or penumbra.
"The Moon will not be shadowed again until January 31, 2018 when a total eclipse is expected to occur", he said.
The eclipse will only cover a small part of the Moon's southern hemisphere and will last for about an hour until 1918 GMT (23:48:10 local time). However, as the three celestial bodies are not perfectly aligned, only part of the moon's surface is covered by the central part of the Earth's shadow.

On Aug. 21, a total solar eclipse will cross the continental United States from Salem, Oregon , to Charleston, South Carolina . Fisher says the total solar eclipse will go from OR all across the middle of the country to Tennessee and North Georgia to SC .
According to PMD, the lunar eclipse will take place between 8:50pm August 7 and 1:51am August 8 of Pakistan time.
This week's partial eclipse is a prelude to the total solar eclipse, which will be visible in North America two weeks later (August 21). Since the moon is above the horizon during this eclipse, so with good weather conditions the entire eclipse should be visible with naked eye.
The partial lunar eclipses will be visible throughout most of Asia (including Qatar), Africa, Europe, Australia, Indian Ocean and Atlantic Ocean, Dr Beshir Marzouk of QCH said.
