In about a few hours, observers in Nigeria will experience a partial eclipse of the Sun. The eclipse actually what is known as a hybrid Eclipse. A hybrid eclipse occurs when a Solar eclipse is seen as Total and Annular at the same time. A total eclipse occurs when the silhouette of the Moon completely obscures the Sun, allowing the much fainter solar corona to be visible. In an Annular eclipse the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring, or annulus, surrounding the dark disk of the Moon. Usually the path of totality where a full (total or Annular) eclipse occurs is at best a narrow path with totality lasting about 2 minutes. On a much larger area observers get to see a partial eclipse.
In todays eclipse, totality will be visible from the northern Atlantic Ocean (east of Florida) to Africa (Gabon ( where it makes landfall), R. Congo, DR Congo, Uganda, South Sudan,Kenya, Ethiopia). It will be partial throughout Nigeria. Viewing times and duration depends on the location with duration of eclipse shortening the further one is from the path of totality. Here are a list of viewing times from a number of locations in Nigeria.
A nice Google info Map is available from NASA showing the times of the eclipse for whatever location.
It is important to note that one should on no condition view the eclipse with the unaided eye. Looking directly at the sun can cause permanent eye damage even after a few seconds of exposure. Viewing requires protection using glasses with special filters (eg Welders goggles) or indirectly (water in a bowl, pin hole).
Solar Eclipse are rare occurrences which happen in a particular place once or twice in a decade. It won’t be a bad idea, weather permitting to go out to see this one.
