The first solar eclipse of 2022 is coming April 30: here's what you should know
passes between Earth and the sun, and, in this case, thereby partly obscures the sun for viewers on Earth. During this month’s partial solar eclipse, a maximum of 54% of the sun will be obscured by the moon.This NASA map by solar eclipse scientist Fred Espenak shows the visibility region of the partial solar eclipse of April 30, 2022 over the southeast Pacific Icean and southern South America.
Solar eclipses are possible due to a chance alignment between the moon, Earth and sun. Since the moon varies in its distance from our planet, an eclipse occurs when it passes in front of the sun at a point when it's farther from Earth than average. A partial solar eclipse occurs when only the penumbra, or the partial shadow, passes over viewers. Therefore, a part of the sun always remains in view during the eclipse.
Viewers within the eclipse's path will see the moon cover a maximum 54 percent of the sun. However, those outside the path might still see a small scallop of the sun hidden by the moon. Therefore, the closer you are to the path of the eclipse, the greater the solar obscuration.The eclipse reaches its maximum phase at 4:41 p.m.
