New Delhi: Skywatchers will find lunar radiance rather dim on the full moon day this Thursday when the penumbral lunar eclipse occurs.

The moon's small entry into the earth's penumbral shadow will produce an extremely subtle dimming of the moon's southern edge which will, however, be difficult to observe with the naked eye, Science Popularisation Association of Communicators and Educators (SPACE) Director CB Devgun said.

The eclipse will be completely visible over Africa and Europe and South America. It could be seen rising over eastern North America and setting over Asia, he said.

The August 6 event is the faintest penumbral eclipse of the year with a penumbral magnitude of 0.899. It will be not be easily visible to the naked eye as the penumbral shadow is very faint, he said.

The eclipse is only of academic interest as no shading can be detected visually.

The penumbral eclipse will begin at 4:34 am on Aug six and end at 7:44 am, he said, adding the greatest eclipse will be at 6:10 am.

The country has already witnessed two penumbral lunar eclipse on Febraury 9 and July 7. Another partial lunar eclipse will be visible on December 31.
