Skywatchers will soon be treated to another cosmic event, a solar eclipse, weeks following the planet parade. This, however, will be an exceptional occurrence. On April 20, a hybrid solar eclipse will occur when the moon blocks sunlight from reaching Earth.
A hybrid solar eclipse contains all three zones of the Moon’s shadow – the umbra, penumbra, and antumbra – and all three types of solar eclipses. As Earth passes through the area where the Moon’s umbra (darkest part of the moon’s shadow) meets its antumbra, a half-shadow that begins where the umbra stops, a hybrid eclipse occurs.
What is a Solar Eclipse?
A solar eclipse is an astronomical occurrence that occurs when the Moon passes between the Sun and the Earth, obstructing all or a portion of the Sun’s light from reaching the Earth. The Moon’s shadow falls on the Earth’s surface, causing temporary darkness in areas of the planet that are in its path.
Solar eclipses are classified into three types: total, partial, and annular. A total solar eclipse occurs when the Moon totally obscures the Sun, leaving only the Sun’s outer atmosphere (known as the corona) visible as a thin strip. A partial solar eclipse occurs when the Moon just partially covers the Sun, allowing some of the Sun’s light to pass through. The Moon appears smaller than the Sun during an annular solar eclipse, and a ring of the Sun’s light is visible around the Moon.
What exactly is a Hybrid Solar Eclipse?
The solar eclipse on Thursday will be a hybrid solar eclipse, a unique event that appears as either an annular or total solar eclipse depending on where it is observed.
During the hybrid solar eclipse, the curvature of the Earth pulls some regions of the eclipse path into the Moon’s umbra, the darkest part of its shadow that causes total solar eclipses, while other areas remain outside the umbra’s reach, resulting in an annular eclipse.
Solar eclipses are extremely infrequent, occurring just approximately once every 18 months. They can only be seen from certain regions of the planet, and those locations will suffer varied degrees of darkness. A solar eclipse is also accompanied by a lunar eclipse that occurs a few weeks before or after the occurrence.
How to watch the 2023 Hybrid Solar Eclipse?
According to In-The-Sky.org, the hybrid total/annular eclipse will be visible from western Australia, East Timor, and eastern Indonesia. “A hybrid total/annular solar eclipse will be seen from western Australia, East Timor, and eastern Indonesia between 07:06 and 12:29 IST,” it stated. The eclipse will not be seen from India or the United States.
According to Space.com, some skywatchers in the aforementioned areas will witness a total solar eclipse, while others will witness a “ring of fire” annular eclipse. Others will see a partial solar eclipse, in which the moon consumes a section of the sun.
“This hybrid solar eclipse will appear as a total or annular solar eclipse when viewed from Western Australia from 10:29 p.m. to 10:35 p.m. EDT on April 19 (0229 to 0235 GMT on April 20), in East Timor from 11:19 p. (spinabifida.net) m. to 11:22 p.m. And EDT (0319 to 0322 GMT) and in Indonesia from 11:23 p.m. to 11:58 p.m. EDT (0323 to 0358 GMT),” Space.com stated.
