UAE to witness only partial solar eclipse on April 8
Sky-gazers around the world are anticipating a spectacular celestial event on April 8, although UAE residents might only witness a partial solar eclipse due to its location.
A total solar eclipse will be visible in North America, passing over Mexico, the US and Canada. The rare astronomical phenomenon will begin over the South Pacific Ocean.
According to the Nasa website, “A total solar eclipse happens when the Moon passes between the Sun and Earth, completely blocking the face of the Sun. The sky will darken as if it were dawn or dusk.”
Experts in the UAE highlighted that solar eclipses, including hybrid ones, provide an opportunity for scientists to study the Sun's corona (the outermost part of the Sun's atmosphere).
Sarath Raj, project director – Amity Dubai Satellite Ground Station and Amisat, Amity University Dubai, said: “A total solar eclipse depends on how large the apparent size of the Moon appears in our sky. The diameter of the Moon is nearly 400 times smaller than that of the Sun, but so is its distance from Earth. This coincidence allows the Moon to totally hide the Sun during an eclipse”.
He explained in a total solar eclipse, the Moon's shadow can be divided into two sections — the umbra, which is the darkest part where the Sun is fully obscured, causing a period of total darkness called totality; and the penumbra, the outer region where the Sun is partly obscured, resulting in a partial eclipse in nearby regions.
“Unfortunately, the upcoming total solar eclipse on April 8, 2024, will not be visible in the UAE as it will be passing over North America. Due to the specific path of the eclipse's totality, the UAE won't have the opportunity to witness the complete blockage of the Sun this time around. The path of totality is the narrow strip on the Earth's surface where observers can experience a total solar eclipse. The duration of totality during a total solar eclipse varies based on the observer's location within the path, ranging from a few seconds to a maximum of about 7 minutes,” Raj added.
“However, on April 8, UAE residents will only experience a partial solar eclipse, with the percentage of the Sun covered varying depending on your location, expected to be around 10-20 per cent. The eclipse will begin at sunrise and the peak time, occurring around 7.45am UAE time will showcase the maximum dimming of the Sun during this celestial event.”
Except for the short phase of a total solar eclipse, when the Moon fully obscures the Sun's luminous surface, it is unsafe to gaze directly at the Sun without eye protection designed for solar observation.
