Following predictions by the National Space Research and
Development Agency (NASRDA) that the eclipse of the sun would be experienced
across the country on September 1, we present seven things you should know
about the eclipse.
1.) It occurs when
the Moon passes between the Sun and Earth, and the Moon fully or partially
blocks the Sun.
2.) It can happen
only at new moon, when the Sun and the Moon are in conjunction as seen from
Earth in an alignment referred to as syzygy
3.) Looking
directly at the photosphere of the Sun (the bright disk of the Sun itself),
even for just a few seconds, can cause permanent damage to the retina of the
eye, because of the intense visible and invisible radiation that the
photosphere emits. The effects of retinal damage may not appear for hours, so
there is no warning that injury is occurring
4.) Viewing the eclipse with Sunglasses do not make viewing the
Sun safe; it is equally very dangerous.
5.) A total solar
eclipse provides a rare opportunity to observe the corona (the outer layer of
the Sun’s atmosphere)
6.) The solar
eclipse of March 20, 2015, was the first occurrence of an eclipse estimated to
potentially have a significant impact on the power system, with the electricity
sector taking measures to mitigate any impact.
7.) It is expected
to occur between 7:15am and 10:03am in Nigeria.
