Nigerians will experience a partial lunar eclipse around on Sunday, November 3rd across the 36 states of the federation.
The Director General of National Space Research and Development Agency, NASRDA , Dr. Saidu Mohammed, disclosed this yesterday during a press conference in Abuja.
Prof. Mohammed said the 2013 penumbral lunar eclipse will be visible throughout the country, Africa, Caribbean, Europe, Africa and Asia.
According to the NASRDA boss, some part of the world will be having total eclipse, while in Nigeria, there will be partial eclipse.
At the unumbral point, experts say, here will be total eclipse, while at the penumbra point, there will be partial eclipse, an observer on earth views it as a partial eclipse.
For observers in Nigeria, the eclipse will occur in he middle of the night when the moon is high overhead. The partial shading will be visible as the slight reddish dimming of the normally bright full moon.
The partial eclipse would be visible in most parts of Nigeria between 12 pm and 4.10pm of Sunday, November 3, 2013. During the partial eclipse, part of the moon will partially block the sun from the reaching the earth through only the outer edge of the earth’s shadow in what scientists call a penumbra lunar eclipse.
Speaking on the development, the Director, Centre for Astronomy, UNN, Prof. Felix Okpara said that partial eclipse usually occur when the moon passes between the sun and the earth, causing a blockage either partially or fully blocking the sun light from shining.
‘‘Considering our culture here, we felt that it is necessary to inform Nigerians so that they will be aware that the world is not coming to an end but that these things happening are natural phenomenon.
‘‘It does not affect the flight, therefore, it is up to the science desk doing studies on astronomy to let us know about this development so that people will understand it well,’’ he said.
According to him, nothing ordinary will happen during the period of the partial eclipse and it can’t hinder any geo-satellite signals.
Speaking on the development, the Director for Centre of Astronomy, University of Nigeria Nsukka, Prof. Felix Okpara said partial eclipse happens when the sun and the moon are in alignment or when the astronomical object temporarily obscured either by passage into the shadow of another body or by having another body pass between and the viewer can see from the end.
According to him, there are two types of eclipse: the solar eclipse and the lunar eclipse. The solar eclipse occurs, when the moon passes between the sun and the earth, the moon fully or partially blocks the sun.
This he said can happen, when the sun and the moon are in conjunction, as seen from the earth is in alignment.
Partial solar eclipse, which is expected in Nigeria on November 3rd this year occurs when the moon partially covers the sun from seeing the earth.
There is also annular eclipse, which he said occurs when moon does not covers the entire dick of the sun, so that a ring of the sun surrounds the shadow of the moon.
He explained that total eclipse is a situation where the sun is completely obscure by the moon.
‘‘This year, the moon obscures the sun and its shadow is cast on the earth. We have the penumbra region and the umbra region. Of this 2013, which comes up on November 3rd, Nigeria is within the penumbra region, where you have the partial eclipse.
‘‘In this case, the moon is not moving at the same speed when it is moving in this steroid pattern. The moon moves around the dialectical orbit round the earth and not moving round the sun. Because of it tilts of the moon around the earth, you may not have eclipse frequently, only at that point when a moon moves in alignment with the sun and the earth, that is the only time you have eclipse.
‘‘The moon is quite nearer to the earth than the sun. The sun is very far away from the earth. The movement of the moon around the earth, at a point when the moon blocks the sun from getting to the earth, that is when you have partial eclipse,’’ he said.
During the partial eclipse on November 3, Prof. Okpara said top part of the sun rays will be cast on earth, as there will not be total black out.
He also said that during this period, internet and facilities will be operating and that there is not going to be night in the day, adding that the Sun lines will also come across and will not affect air services.
Solar eclipse recorded in Nigeria history took place in 1898, 1947, 1959,2001 and 2006.
