The last eclipse out of the four eclipses due for this year will occur today when the shadow of the earth falls on the moon.
Professor Chandana Jayaratne of Department of Physics, Colombo University said this is a penumbral lunar eclipse, occurring with the moonrise from the eastern horizon today.
The eclipse begins at 5.45pm today with the moon entering the penumbra of the earth's shadow and ends at 10.21pm when the moon leaves the penumbra.
In a penumbral eclipse, the moon will not enter into the dark shadow of the earth, but the lighter-shadow.
Penumbral eclipses are difficult to observe, especially during the early and late stages.
