When does partial solar eclipse occur?

Answer 1

A partial solar eclipse occurs when the moon and the sun are not perfectly aligned, but the moon still passes in front of the sun, partially obscuring it's disc. Anywhere from a small percentage of the sun, to 90%+ of it's disc may be covered by the moon's disc, but the sun will not be completely covered at any time, as it is in a total eclipse.

Answer 2

A solar eclipse occurs when the moon passes between an observer on the earth and the sun. However, the lines of sight from different parts of the earth are different and so there will be regions on the surface of the earth for which the moon covers more of the sun than elsewhere. There may be a central belt where the moon will align perfectly and the eclipse will be total but on either side of this belt the eclipse will be partial.

Also, the orbits of the earth around the sun and the moon around the earth are not exactly in the same plane. So sometimes when the moon passes between the earth and sun it is above the plane of the earth's orbit and sometimes lower. This means that the moon does not fully block the sun from anywhere on the earth.

Answer 3

A partial solar eclipse occurs when the Moon partially blocks the Sun's disc, casting a shadow on Earth. This can only happen during a new moon phase when the Moon passes between the Earth and the Sun but is not perfectly aligned.
