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.
