Partial Solar Eclipse

Partial Solar Eclipse

  • On October 25, various portions of India witnessed a partial solar eclipse for the first time in more than ten years.
  • It also marks the last solar eclipse of the year.

A solar eclipse is what?

  • A solar eclipse occurs when the Moon moves in front of the Sun, blocking some of the Sun's light from reaching Earth.
  • An eclipse never occurs on its own. A solar eclipse often occurs two weeks either before or after a lunar eclipse.

Recent partial solar eclipse visibility:

  • From sections of Europe, Northern Africa, and a sizable portion of western and central Asia, the eclipse was visible.
  • With the exception of few regions in the Northeast, it was visible throughout most of India.

Solar eclipse types:

  • A total solar eclipse occurs when the Moon totally blocks out the Sun.
  • Eclipse with an annulus: In an annular solar eclipse, the Moon will partially obscure the Sun yet leave its edge visible.
  • Partial solar eclipse: When the sun, moon, and earth are not exactly lined up, a partial solar eclipse takes place. As a result, a portion of the sun's surface appears to have a black shadow.
  • A partial solar eclipse has three phases: its commencement, its apex, and its ending.
  • The moon moves over the disc of the sun in its initial phase, reaching its maximum when the largest portion of the disc is covered.
  • The third phase occurs when the moon begins to move away from the earth, allowing sunlight to pass through.
  • The fact that the partial solar eclipse may only occur during a new moon makes it special.

What makes the latest occurrence unusual?

  • About twice a year, a partial eclipse takes place somewhere on Earth. There might be a range in the annual total of partial eclipses.
  • They can happen on their own or in conjunction with a total solar eclipse, in which case the partial eclipse is visible before and after totality.

Concerns

  • Even for a little time, it is not advised to see an eclipse with the naked eye. Even though the Moon conceals the majority of the Sun, it can nevertheless permanently harm the eyes and cause blindness.
  • The retina can be harmed by ultraviolet photons even if the eclipse may be apparent to the unaided eye.
